Fachsprache (Terminologie) Viele medizinische Fachbegriffe kommen aus dem Griechischen oder aus dem Lateinischen. Man muss aber nicht perfekt griechisch oder lateinisch sprechen, um die medizinischen Fachbegriffe „zu einem Wortgebäude zusammenbauen“ zu können. Meistens ist es viel einfacher, als man denkt! Wir unterscheiden in der Hauptsache drei Typen von Wortteilen: 1. Wortstamm („word roots“) 2. Nachsilben („suffixes“ 3. Vorsilben („prefixes“) Beispiel: Gelenk / schmerzen Wortstamm Nachsilbe Arthr / algie An diesem Beispiel sehen wir, dass die Wortendung „-algie“ immer die Bedeutung Schmerzen hat. Wenn wir nun andere Wortstämme mit der Endung „-algie“ kombinieren, bekommen wir entsprechende Wortkombinationen, die alle auf „ - schmerzen“ enden, wie z.B. Ceph / algie Kopfschmerzen Neur / algie Nervenschmerzen Lumb / algie Lendenschmerzen My / algie Muskelschmerzen 1 Wir sehen also, dass die einzelnen „Wortteile“ der Schlüssel zum Verständnis der medizinischen Fachausdrücke sind. Word Parts are the Key Word roots or combining forms usually, but not always, indicate the involved body part. Word roots or combining forms contain the basic meaning of the term. Compound words can be formed when two or more word roots are used to build the word. Suffixes come at the end of a word. Suffixes usually, but not always, indicate the disorder, the procedure or the disease. Prefixes always come at the beginning of a word. Prefixes usually, but not always, indicate location, number, status or time. Combining Vowels are necessary to make the medical term easier to pronounce. A combining vowel may be needed between the word root and the suffix. The letter “o” ist the most commonly used combining vowel. Üben und studieren Sie nun gründlich die folgenden Beispiele für „zusammengesetzte Fachbegriffe“! For example: hydrotherapy (hydr/o/therapy) HYDR word root = + O + THERAPY vowel word root HYDROTHERAPY compound word 2 microscope (micr/o/scope) MICR word root = + + O vowel SCOPE word root MICROSCOPE compound word RULES FOR USING THE COMBINING VOWEL Rule 1: Do not place a vowel between a prefix and the word root. Rule 2: Do not place a vowel between a suffix and the word root when the suffix beginns with a vowel. For example: An often used suffix is “-itis” (= inflammation). When the word root “neur/o” ( “neur” means nerve) is joined with the suffix “itis”, the combining vowel is not used because “-itis” begins with a vowel. neuritis (neur/itis) NEUR word root + ITIS = NEURITIS suffix word 3 Rule 3: A combining vowel is used when the suffix begins with a consonant. For example: When the word root “neur/o” ( “neur” means nerve) is joined with the suffix “-plasty” (surgical repair), the combining vowel “o” is used because “-plasty” begins with a consonant. neuroplasty (neur/o/plasty) NEUR + word root = O + PLASTY vowel suffix NEUROPLASTY word encephalotomy (encephal/o/tomy) ENCEPHAL word root + O + TOMY vowel suffix The ending that follows a word root is a suffix. You can change the meaning of a word by putting another part after it. 4 For example: gastroduodenoscopy (gastr/o/duoden/o/scopy) + GASTR word root O + vowel DUODEN + + O word root SCOPY vowel suffix electrocardiography (electr/o/cardi/o/graphy) ELECTR + word root O + O + CARDI vowel word root GRAPHY vowel suffix appendectomy (append/ectomy) APPEND word root + ECTOMY suffix 5 + COMBINING FORMS, SUFFIXES AND PREFIXES Here are some examples of combining forms, suffixes and prefixes that are commonly found in medical terms.

Wir essen, schlafen, bewegen uns, atmen, denken, sprechen, verdauen Speisen und vieles mehr. Dies ist alles nur möglich, weil jede „Produktionsstätte“, jede einzelne „Fachabteilung“ -wir können auch Organsystem dazu sagen- mit der anderen Fachabteilung eng zusammenarbeitet. Je nachdem aus welcher Blickrichtung wir unseren Körper betrachten, sehen und analysieren wir ihn. Der Biologe sieht vor allem die Milliarden von Körperzellen, die helfen, den Körper wachsen, gedeihen und mit den verschiedenen Organen zusammenarbeiten zu lassen. Der Chemiker sieht natürlich an erster Stelle die unzählbaren Atome und Moleküle (Atomverbindungen), die in jeder Sekunde unseres Lebens chemische Reaktionen eingehen. Der Physiologe untersucht die grundlegenden Lebensprozesse (z.B. Enzymreaktionen, hormonelle Regelkreise usw.). Für den Ernährungswissenschaftler ist der menschlichen Körper eine Ansammlung von Proteinen, Kohlenhydrate, Eiweiße, Mineralien, Spurenelemente usw..Für den Ingenieur ist der Körper wiederum eine unglaubliche Biomaschine, die sich selbst kontrolliert und gegebenenfalls auch selbst repariert. Übungsaufgabe: Beschreiben Sie auf deutsch die folgenden Abbildungen „vom Atom“ zum „Körper“: Atom Moleküle Zellorganelle Körperzelle Gewebe Organ Organsystem Körper 34 Levels of organization The human body is highly organized from the single cell to the total organism. 35 The anatomy of the human body is composed of different levels of organization.

Sagittalebene Außerdem gibt es noch folgende Begriffe: transversal: senkrecht zur Sagittalebene (rechts-links) longitudinal: entlang der Körperlängsachse oder senkrecht zur Transversalebene (oben-unten) sagittal (sagitta „Pfeil“): parallel zur sagittalen Achse oder senkrecht zur Frontalebene (vorne-hinten) median: in der Medianebene Transverse plane The transverse plane, also called horizontal plane, cuts the body into upper and lower parts. Frontal plane These are known as The frontal the cranial plane runs lengthwise from side to side, dividing the body into Median sagittal plane ventral and dorsal (front and back) The sagittal plane runs sections. lengthwise from front to back and divides the body into right and left sides. A median sagittal cut produces two equal halves, each containing 51 an arm and a leg. Die Körperhöhlen Körperhöhlen sind mit Epithel ausgekleidete Hohlräume des Körpers. Sie sowohl in sich geschlossen sein oder aber mit anderen Räumen, bzw. der Umwelt in Verbindung stehen. Die wichtigsten Körperhöhlen sind: 1. die Peritonealhöhle (Cavitas peritonealis) 2. die Pleurahöhle (Cavitas pleuralis) 3. die Herzbeutelhöhle (Cavitas pericardii) Außerdem gibt es noch och weitere Körperhöhlen, wie z.B.: 4. die Gelenkhöhle (Cavum articulare) 5. die Nasenhöhle (Cavum nasi) 6. die Schädelhöhle (Cavum cranii) 7. die Brusthöhle (Cavitas thoracis, auch Thorakalraum) Body Cavities A body cavity is a space within the body that contains and protects the internal organs. cranial cavity spinal cavity thoracic cavity diaphragm abdominal cavity pelvic cavity 52 There are two main cavities of the human body, the dorsal cavity and the ventral cavity. Each cavity is divided into subcavities. The dorsal cavity spinal cavity The ventral cavity Cranial pelvic cavity thoracic cavity abdominal cavity The dorsal cavity protects the structures of the nervous system. The dorsal cavity is divided into two parts: The cranial cavity, located within the skull, protects the brain. The spinal cavity, located within the spinal column, protects the spinal chord. The ventral cavity contains and protects many of the body organs. The ventral cavity is divided into three parts: The thoracic cavity, also known as the chest cavity, protects the heart and the lungs. The diaphragm is a muscle that separates the thoracic and abdominal cavities. The abdominal cavity contains primarily the major organs of digestion. The pelvic cavity is the space formed by the pelvic. The pelvic cavity contains primarily the organs of the reproductive and excretory systems. 53 Was gehört zusammen?

Der Oberbauch oder das Epigastrium ist der der von Rippen eingefasste Bauchbereich oberhalb des Bauchnabels: Er umfasst folgende Regionen: Regio epigastrica Regio hypochondriaca Mittelbauch Der Mittelbauch oder das Mesogastrium ist der freie Mittelbereich um den Bauchnabel herum, der annähernd die Form eines schmalen Korsetts hat. Er besteht aus: Regio umbilicalis Regio lateralis Der Unterbauch oder das Hypogastrium ist der vom Becken eingefasste Bauchbereich unterhalb des Bauchnabels. Er umfasst folgende anatomische Regionen: Regio pubica Regio inguinalis 55 Divisions of the abdomen Umbilicus = Belly Button RUQ LUQ RLQ LLQ To describe where an organ or a pain is located, the abdomen is divided in four quadrants. 1. 2. 3. 4.

Wer meint, dass die Haut „nur“ eine einfache „Hülle“ des Menschen sei, der irrt. Die Haut ist mit einer Oberfläche von ca. 2 m² das größte Organ des Menschen und außerdem ein lebenswichtiges Organ, das viele Aufgaben wahrnimmt. Was bietet uns die Haut? Schutz bei chemischen Schädigungen Schutz gegenüber Druck, Stößen und Reibung Schutz vor dem Eindringen von Mikroorganismen Schutz vor dem Verlust von Wasser und Wärme Schutz vor Kälte, Hitze und Strahlung Schutz vor Überhitzung (Wärmeregulation z.B. durch Schweißabsonderung Verdunstungskälte) 7.

Durch Verschmelzen einiger Knochen besitzt der Erwachsene noch ca. 206 Knochen. Diese Knochen, sowie die dazugehörenden Knorpel und Bänder gehören zum Skelett ( = passiver Bewegungsapparat). Nach ihrer Form können wir die verschiedenen Knochen in Röhrenknochen (z.B. Oberarmknochen, Schienbein, Wadenbein usw.), platte Knochen (z.B. Brustbein) und kurze, unregelmäßige Knochen (z.B. Hand- und Fußwurzelknochen, Wirbel usw.) einteilen. Das Knochengewebe besteht aus ca. 20% Wasser, 25% organischen Substanzen und 55% anorganischen Salzen (z.B. Kalziumphosphat, Kalziumkarbonat, usw.). Diese Knochensalze verleihen dem einzelnen Knochen seine Festigkeit, während die organischen Substanzen für seine Elastizität sorgen. Das Knorpelgewebe zeichnet sich durch eine hohe Druckfestigkeit und Elastizität aus. Am häufigsten findet man daher Knorpelgewebe an den Körperstellen, wo hohe mechanische Belastungen auftreten (z.B. Bandscheiben der Wirbelsäule). Das Bindegewebe sorgt für hohe Zug- und Biegefestigkeit. Bindegewebszellen und sogenannte kollagene Fasern finden wir daher vor allem in den Bändern und Sehnen. 64 Für den nachfolgenden Text benötigen Sie einige neue Vokabeln.

The average human adult skeleton has 206 bones. The skeleton has two main parts: the axial skeleton and the appendicular skeleton. The axial skeleton consists of the skull, the spine, the ribs and the sternum (breastbone) and includes 80 bones. The appendicular skeleton includes two limb girdles (the shoulders and pelvis) and their attached limb bones. This part of the skeletal system contains 126 bones, 64 in the shoulders and upper limbs and 62 in the pelvis and lower limbs. The skeleton is not just a movable frame, however; it is an efficient factory which produces for example red blood cells from the red bone marrow . The bones are also a storehouse for minerals - calcium, for example- which can be supplied to other parts of the body. The bones are made up of several different tissues and have different shapes. The tissues which form the bones are the following connective tissues: bone tissue fibrous tissue cartilage tissue adipose tissue The skeletal system provides at least five functions for the human body: 1. Protection 2. Support 3. Movement 4. Mineral Storage 5. Blood Cell Formation 67 There are five kinds of bones that develop in the body: 1. Long bones are found in the arms (i.e. humerus) 2. Short bones include the Carpals (wrist) and tarsals (ankle). 3. Flat bones such as the sternum. 4. Irregular bones such as mandible (jawbone) and vertebrae. 5. Sesamoid bones are seed-shape, found in joints (i.e. patella).

A hinge joint allows extension and retraction of an appendage. Hinge joints are found in the knees, elbows, fingers, and toes. 79 A condyloid joint is similar to ball and socket but with less movement. The wrist is a condyloid joint. A ball and socket joint allows for radial movement in almost any direction. Ball and socket joints are found in the shoulders and hips. A saddle joint allows movement back and fourth and up and down. The only saddle joint in a human body is the thumb. 80 5 The Muscular System Während das Skelett zum passiven Bewegungsapparat gezählt wird, bildet die Muskulatur den aktiven Teil des Bewegungsapparates. Der menschlichen Körper besteht aus hunderten von Einzelmuskeln von unterschiedlicher Größe und Form. Alle Muskeln besitzen die Eigenschaft , sich auf entsprechende Nervenreize hin in Längsrichtung zusammenziehen zu können (= Kontraktilität). Grundsätzlich unterscheiden wir zwischen folgenden drei Muskelgewebearten: 1. Glattes Muskelgewebe, wie z.B. die Eingeweidemuskulatur. Glattes Muskelgewebe ist nicht willkürlich beeinflussbar und spezialisiert auf langandauernde, aber schwächere Leistung. Glatte Muskulatur ist nicht ermüdbar. 2. Quergestreiftes Muskelgewebe, wie z.B. die Skelettmuskulatur. Quergestreiftes Muskelgewebe ist willkürlich beeinflussbar, spezialisiert auf kurzfristige, starke Leistung und relativ schnell ermüdbar. 3. Netzförmiges Muskelgewebe, wie z.B. die Herzmuskulatur. Das Herzmuskelgewebe ist nicht willkürlich beeinflussbar und spezialisiert auf relativ starke Dauerleistung. Das Herzmuskelgewebe ist nicht ermüdbar. Jeder Muskel kann durch seine Kontraktion (Zusammenziehung) sich aktiv nur verkürzen. Für die Gegenbewegung benötigt jeder Muskel einen Gegenspieler (Antagonisten). Für seine Arbeit hat jeder einzelne Muskel einen großen Energiebedarf. Daher durchziehen zahlreiche Blutgefäße (Kapillaren) die Muskulatur, um die notwendige Sauerstoff- und Nährstoffversorgung zur Verfügung zu stellen. Zu jedem Zeitpunkt befinden sich die Muskeln in kontrahiertem Zustand. Die Muskelkontraktionen versetzen den Muskel in einen gewissen Spannungszustand (= Tonus) und geben dem Körper Halt . 81 Für den nachfolgenden Text benötigen Sie einige neue Vokabeln.

The muscular system consists of a large number of muscles (over 600 skeletal muscles in the human body). The skeletal muscles carry out several important body functions (e. g. movement, heat production, posture etc.) A skeletal muscle consists of several tissue types. Skeletal muscles attach bones by tendons. At movable joints (diarthroses), a contracting muscle can pull on a bone to produce a movement. There are one of the following motions (actions): Flexion bending, decreasing the angle at a joint Extension straightening out, increasing the angle at a joint Abduction moving a limb away from the midline of the body Adduction moving a limb toward the midline of the body Rotation pivoting a structure – the atlas (C1) and skull can rotate on the axis (C2) Lateral view of the biceps Lateral view of the flexing the forearm triceps extending the a b c Anterior view of skull and neck muscles : a) head is held stationary; b) rotated to its left and c) to its right 84 Types of muscles There are three types of muscles: a) Skeletal muscle, which covers and move the skeleton b) Cardiac(heart) muscle, which pumps blood around the body c) Smooth muscle, which is found in the walls of the digestive tract, blood vessels and the genital and urinary tracts a) Cardiac muscle Short, branching, interlinked fibers form a network within the wall of the heart Cardiac muscles contract rhythmically and continually without tiring b) Skeletal muscle This type of muscle is formed of long, strong, parallel fibers. Skeletal muscles are able to contract quickly and powerfully, but can do so only for short periods of time. c) Smooth muscle The fibers of smooth muscles are short, spindle-shaped, and thinner than skeletal muscle fibers. Smooth muscle cells form sheets of muscle that can contract for prolonged periods. 85 Flexors & Extensors FLEXORS Muscle fibers consist of myofibrils, mitochondria, an extensive endoplasmic reticulum, and many nuclei. A flexor muscle is a skeletal muscle whose contraction bends a joint, decreasing the angle between components of a limb, such as straightening the wrist. This action is known as flexion. EXTENSORS The type of muscle that has the opposite effect is the extensor muscle, which opens a joint, increasing the angle between components of a limb, like extending the arm. Similar actions are called extension. The biceps and triceps are an example of an antagonistic pair of muscles. Antagonistic pairs are responsible for the movement of the entire skeleton.

Der kleine Körperkreislauf – er wird auch Lungenkreislauf genannt- besteht zwischen Herz und Lungen. Das mit Kohlendioxid (CO2) beladenen Blut gelangt in die Lunge und nimmt dort Sauerstoff (O2) auf. Der große Blutkreislauf –auch Körperkreislauf genannt- verteilt dann dieses sauerstoffreiche Blut vom Herzen aus in die verschiedenen Körperorgane und Körpergewebe. Überflüssige und schädliche Abfallstoffe werden vom Blutkreislauf an den Ort ihrer Ausscheidung (z.B. Nieren) transportiert. Zum Körperkreislauf gehört neben den Blutgefäßen (Aorta, Arterien, Venen, Kapillaren usw.) auch das Herz, das durch seine Pumpfunktion den Blutfluss in Gang hält. Auch das Lymphsystem mit der Lymphe gehört zum Kreislaufsystem. Für den nachfolgenden Text benötigen Sie einige neue Vokabeln.

Arteries and veins Arteries carry blood away from the heart and veins carry blood toward the heart. Most arteries contain brigth red, high-oxygen blood. But the pulmonary arteries, which run from the heart to the lungs, contain dark reddish-blue blood, which is low in oxygen. Most veins contain blood that is low in oxygen, except for the pulmonary veins, from the lungs to the heart, which contain oxygen-rich blood. At any instant, three-quarters of our blood is in veins, one-fifth in arteries, and one-twentieth in capillaries.

The aorta is the _ _ _ 1 9 _ _ _ _ _ _ 2 0 _ _ _ _ in the body. lt has two branches: the ascending aorta, supplying the arms and _ _ 2 1 _ _ ; and the descending aorta, supplying the lower part of the body. The descending aorta passes from the thorax through the diaphragm to the abdomen, where it is called the _ _ _ _ 2 2 _ _ _ _ _ _ _ 2 3 _ _ _ . The coeliac axis, which branches off the abdominal aorta, supplies the stomach, _ _ 2 4 _ _ _ and spleen. Below this the renal arteries branch off to the _ _ _ _ 2 5 _ _ _ and the mesenteric arteries to the intestines. Finally the abdominal aorta branches into two iliac arteries which run into the _ _ 2 6 _ _ _ _ . The internal iliac artery supplies the reproductive organs while the external iliac artery becomes the femoral artery which is the main artery of the lower _ 2 7 _ _ _ . The femoral artery supplies the thigh muscles and becomes the popliteal artery at the knee. This divides into the anterior and posterior tibial arteries. The anterior tibial artery supplies the front of the leg and is continued to the foot as the dorsalis pedis artery. The posterior tibial artery supplies the back of the leg and reaches the sole of the foot as the _ _ _ 2 8 _ _ _ _ _ _ 2 9 _ _ _ which forms the plantar arches. Two coronary arteries branch off the ascending aorta, which then passes upwards as the innominate artery. This divides into the subclavian and _ _ 3 0 _ _ _ _ _ arteries. The _ _ 3 1 _ _ _ _ _ _ _ _ artery passes behind the clavicle and enters the armpit where lt becomes the axillary artery. The brachial artery continues for the length of the upper arm until the _ _ 3 2 _ _ _ where it divides into the radial and ulnar arteries, culminating in the palmar arches in the hand. 94 The carotid artery passes upwards to the neck and has _ _ 3 3 _ _ main branches, the facial, temporal, occipital and ‚naxillary arteries.

Work with a partner Translate the sentences Dictate the sentences to each other. Artery structure Arteries are elastic vessels that transport blood away from the heart. The largest artery of the body is the aorta. The aorta originates from the heart and branches out into smaller arteries. The smallest arteries are called arterioles. These vessels connect with the venous system through capillaries. Arteries are thick-walled, hollow tubes. The artery wall consists of three layers: 1. Tunica Adventitia – a fibrous outer covering 2. Tunica Media – a middle layer of muscle and elastic tissue 3. Tunica Intima – an endothelial layer made of squamous epithelial tissue 3 2 1 Arterioles are smaller than those of arteries. They have a similar structure. Capillaries are the smallest blood vessels. Their walls are one cell thick and porous, thus allowing the passage of gases like oxygen and carbon dioxide and nutrients. The interstitial fluid carries food, vitamins, mineral salts and hormones out to the tissues and collects waste products, especially carbon dioxide and urea, from them. 96 TRUE / FALSE If the statement is true, write T on the line. If the statement is false, write F on the line. _____ a) The aorta is the main artery of those that carry oxygenated blood from the heart to the tissues of the body. _____ b) The middle layer of the artery wall is called tunica intima. _____ c) Arterioles are smaller than capillaries. _____ d) A large amount of water filters out through the capillary walls. This liquid is called interstitial fluid. Vein structure Schematic drawing of a vein 1 4 2 Veins have three-layer ed walls. The walls of the veins are much thinner and less muscular than those of arteries. Veins have thin, flexible walls that can expand to hold large volumes of blood. 3 Deoxygenated blood returning to the heart through the veins is circulating at low pressure. The diameter of a vein is greater than a corresponding artery. Many veins have valves which keep blood from flowing backwards.

The figure below shows the internal parts of the heart: Übersetzen Sie bitte die folgenden Begriffe: aorta left atrium left ventricle mitral valve pulmonary artery pulmonary valve right atrium right ventricle septum superior vena cava tricuspid valve 100 The heart is a hollow, muscular, cone-shaped organ. It's located a little to the left of the middle of the chest. It lies between the lungs in an area called mediastinum, behind the body of the sternum with two-thirds of its bulk on the left side. The circular base of the cone isd directed upwards and to the right and the apex points downwards, forwards and to the left. The heart measures about 12 cm from base to apex and about 9 cm in width. The heart is about 6 cm thick. The heart is approximately the size of its owner´s fist. The heart muscle is special because of what it does. The heart sends blood around the body. The blood provides the body with the oxygen and nutrients it needs. It also carries away waste. The heart is sort of like two pumps in one. The right side of the heart receives blood from the body and pumps it to the lungs. The left side of the heart does the exact opposite: It receives blood from the lungs and pumps it out to the body.

Er erzeugt elektrische Impulse, die an den AV-Knoten (=2) weitergeleitet werden. Von dort geht die elektrische Erregung zum Hiss´schen Bündel (=3), dann weiter in die Tawara- Schenkel (=4) und die Purkinje-Faser (=5), 103 die in den Herzwandungen liegen. Sobald ein elektrischer Impuls die einzelnen Herzmuskelzellen erreicht, kommt es zur Muskelkontraktion. Übersetzen Sie bitte den folgenden Text: The sinoatrial node (SAN), located within the wall of the right atrium (RA), normally generates electrical impulses that are carried by special conducting tissue to the atrioventricular node (AVN). Upon reaching the AVN, located between the atria and ventricles, the electrical impulse is relayed down conducting tissue (Bundle of HIS) that branches into pathways that supply the right and left ventricles. Electrical impulses generated in the SAN cause the right and left atria to contract first. Depolarization (heart muscle contraction caused by electrical stimulation) occurs nearly simultaneously in the right and left ventricles 1-2 tenths of a second after atrial depolarization. The entire sequence of depolarization, from beginning to end (for one heart beat), takes 2-3 tenths of a second. All heart cells, muscle and conducting tissue, are capable of generating electrical impulses that can trigger the heart to beat. Under normal circumstances all parts of the heart conducting system can conduct over 140200 signals (and corresponding heart beats) per minute. The SAN is known as the "heart's pacemaker" because electrical impulses are normally generated here. At rest the SAN usually produces 60-70 electrical impulses a minute. It is the SAN that increases its' rate due to stimuli such as exercise, stimulant drugs, or fever. Should the SAN fail to produce impulses the AVN can take over. The resting rate of the AVN is slower, generating 40-60 beats a minute. The AVN and remaining parts of the conducting system are less capable of increasing heart rate due to stimuli previously mentioned than the SAN. The Bundle of HIS can generate 30-40 signals a minute. Ventricular muscle cells may generate 20-30 signals a minute. Heart rates below 35-40 beats a minute for a prolonged period usually cause problems due to not enough blood flow to vital organs. Problems with signal conduction, due to disease or abnormalities of the conducting system, can occur anyplace along the heart's conduction pathway. 104 Abnormally conducted signals , resulting in alterations of the heart's normal beating, are called arrhythmias or dysrrythmia. Systole is….. the rhythmic contraction of the heart, especially of the ventricles, by which blood is driven through the aorta and pulmonary artery after each dilation or diastole. ventricular systole is…. the contraction of the cardiac ventricles by which blood is forced into the aorta and pulmonary artery. Atrial systole is…. the contraction of the atria by which blood is propelled from them into the ventricles. Diastole is …. the phase of the cardiac cycle in which the heart relaxes between contractions; specifically, the period when the two ventricles are dilated by the blood flowing into them. 105 7 The Digestive System Um funktionieren zu können, muss die „Biomaschine Mensch“ Energie in Form von Nahrung aufnehmen. Durch komplizierte physikalische , chemische und biologische Prozesse müssen die Kohlenhydrate, Fette und Eiweiße der Nahrung vor ihrer „Verwertung“ in geeigneter Weise umgearbeitet werden, damit sie vom menschlichen Organismus aufgenommen werden kann. Diesen Prozess nennen wir Verdauung. Er lässt sich in 2 Phasen unterteilen: In der ersten Phase wir die Nahrung mechanisch zerkleinert (z.B. im Mund mittels der Zähne ). In der zweiten Phase stehen die biochemischen Prozesse im Vordergrund. Verschiedene Drüsen im Verdauungsapparat mit ihren Sekreten sorgen dafür, dass die Nahrung in Stoffe umgewandelt werden, die vom Organismus aufgenommen werden können. Die Verdauung ist also ein Prozess der ständigen chemischen Vereinfachung von aufgenommenen Nahrungsmitteln. Der Verdauungsapparat, der sich vom Mund bis zum After erstreckt ist ca. 12 m lang und kann mit einem langen Rohr verglichen werden, dessen einzelne Abschnitte sich in Form, Länge und Volumen unterscheiden. Der erste Teil ist der Mund. Er beginnt an den Lippen und endet an der Schlundenge. Der Schlund liegt an der Kreuzung zwischen Verdauungs- und Atmungsapparat. Der nächste Abschnitt ist die Speiseröhre, die den Schlund mit dem Magen, dem weitesten Teil des Verdauungsapparates, verbindet. Durch den Pförtner, der von zirkulären Muskelfasern gebildet wird, steht der Magen mit dem Darm in Verbindung. Der Darm gliedert sich in den ca. 6,8 m langen Dünndarm und den ca. 1,8 m langen Dickdarm. Der Dünndarm wird wieder unterteilt in Zwölffingerdarm, Leerdarm und Krummdarm. In den Zwölffingerdarm geben zwei wichtige Organe ihr Sekret ab: die Bauchspeicheldrüse und die Leber, aber auch zahlreiche andere Drüsen. Der letzte Anteil des Dünndarmes, der Krummdarm, steht über die sogenannte Bauhinsche Klappe (Ileocoecalklappe) mit dem Dickdarm in Verbindung, der mit dem Blinddarm beginnt. Der Dickdarm zieht an der rechten Bauchseite als Colon ascendens (aufsteigender Dickdarm) nach oben, als Colon transversum (Querteil des Dickdarms) zieht er von der Leberunterseite nach links, an der linken Bauchseite als Colon descendens (absteigender Dickdarm) nach unten. Auf ihn folgt nach einem s-förmigen Dickdarmteil (Sigma) der Mastdarm. dieser öffnet sich mit dem Afterschließmuskel nach außen. Die Innenseite des gesamten Darms wird von einer für den Darm ganz spezifischen Schleimhaut gebildet, die zur Nahrungsaufnahme fähig ist. Die wichtigsten Funktionen des Dickdarms sind die Synthese von Vitaminen (z.B. Vitamin K) und Abbau von Nahrungsbestandteilen. Der Stuhl, der über den After ausgeschieden wird, enthält nicht nur Nahrungsmittelrückstände, sondern vor allem abgeschilferte, überalterte Darmschleimhaut sowie auch Darmbakterien. 106 Digestion Most molecules in the human diet are too large to be used in metabolism. The digestive system prepares food molecules for use in the body. It accomplishes this through physical digestion and chemical digestion. Physical digestion begins in the oral cavity with mastication. Chemical digestion occurs when the chemical makeup of dietary molecules is changed. Throughout the digestive tract, organic catalysts, called enzymes, accelerate these chemical changes. 107 Salivary Glands create mucus to aid in digestion Tongue Uses for speaking and chewing Esophagus Path to Stomach Stomach stores and breaks down ingested food Liver produces bile Gall Bladder stores bile, which aids in digesting Pancreas produces digestive enzymes and bicarbonate solution Small Intestine (duodenum, jejunum, and ilium) digests carbohydrates, fats, and proteins and absorbs nutrients Large Intestine absorbs the water and ions 108 Ordnen Sie bitte die folgenden Texte den entsprechenden Nummern der folgenden Zeichnung zu! Nr. The digestive tract opens out of the body at the anus. The throat is connected to the stomach by this muscular tube, wihich is closed at the top except during swallowing. This organ is a J-shaped bag that secretes 3 liters of gastric juice each day. It leads to the small intestine. This organ is the largest internal organ. Each day it produces up to 1 liter of the digestive juice bile. This passage, commonly called the throat, connects the mouth to the esophagus and trachea. This tube is 1,5 m long: It is connected to the small intestine and consists of the cecum, colon, and rectum. In the colon, undigested food is formed into feces. This tube is 5 m long. It connects the stomach to the large intestine and consists of the duodenum, and ileum. Three pairs of salivary glands secrete 1,5 liters of saliva into the mouth each day. 6 7 5 4 8 3 2 1 109 The liver Die Leber ist die größte Drüse des menschlichen Körpers.

Beide Nieren sind von bohnenförmiger Gestalt, dunkelbraunrot gefärbt und haben eine glatte Oberfläche. Sie bestehen aus einer Rindenschicht (Cortex), die von Millionen von Nierenkörperchen (Nephrone) gebildet wird, und aus einer Markschicht (Medulla), in der sich zahlreiche Harnkanälchen (Tubuli) befinden. Jeweils in der Nierenmitte treten sowohl die Nierenarterie in die Niere als auch die Nierenvene aus der Niere. Auch jeweils im Nierenbecken (Pelvis) entspringt ein Harnleiter (Ureter), der den Harn bis zur Harnblase (Vesica urinaria) leitet. In ihr wird der Harn vorübergehend gespeichert und durch die Harnröhre (Urethra) abgegeben. Die kleinste funktionelle Arbeitseinheit der Nieren sind die Nierenkörperchen. Sie liegen in der Nierenrinde. Jeder Mensch besitzt etwa 2 bis 3 Millionen Nierenkörperchen (= Nephrone). Jedes einzelne Nephron besteht aus einem Blutkapillarknäuel (= Glomerulum), das von einer Kapsel (=Bowman´sche Kapsel) umschlossen wird. An diese schließt sich ein feines Harnkanälchen in Form eines vielfach gewundenen Röhrchens an (= proximaler Tubulusapparat Henle´sche Schleife distaler Tubulusapparat)). Die Harnbildung beginnt in den Nierenkörperchen bzw. in den Nierenkanälchen. Wenn das Blut (ca. 1500 l Blut pro Tag) durch das Blutkapillarknäuel fließt, werden im Nierenkörperchen Wasser und darin gelöste Stoffe, wie Traubenzucker, Harnstoff, Salze, aus dem Blut ausgeschieden. Diese Flüssigkeit nennt man Ultrafiltrat oder Primärharn und fließt von der Kapsel in Richtung Tubulusapparat weiter. Da die Kapillarwände äußerst feine Poren besitzen, können Stoffe, die größer als die Poren sind (z.B. Eiweiße, rote Blutzellen), nicht ausgefiltert werden. Es werden ca. 150 l Primärharn pro Tag gebildet. Er enthält außer Eiweiß nahezu alle im Blut gelösten Stoffe. Durch die sogenannte Rückresorption werden ca. 148,5 l Primärharn in den mehrfach gewundenen Harnkanälchen (= Tubulusapparat) der größte Teil des Wassers und der Stoffe wieder dem Blut zugeführt. Aus den Harnkanälchen gelangt der Sekundärharn oder Endharn (Urin) in kleine Sammelröhrchen, die wiederum in das Nierenbecken münden. Von dort aus tröpfelt der Harn Tag und Nacht in den Harnleiter, einen etwa 30 cm langen Schlauch, dessen Muskeln den Harn abwärts zur Harnblase befördern. Diese füllt sich allmählich und speichert zeitweise den Harn. Die Muskeln der Blasenwand pressen den Harn dann durch die Harnröhre aus dem Körper. Die männliche Harnröhre führt gemeinsam mit dem Samenleiter als Harnsamenröhre durch den Penis und ist etwa 20 cm lang. Die weibliche Harnröhre ist dagegen nur 4 cm lang. 112 Adrenal Glands Renal Cortex Kidney Renal Pelvis Medulla Calyces Ureter Bladder Uretha the urinary system 113 Übersetzen Sie bitte die folgenden Fachbegriffe: adrenal glands bladder calyces kidney medulla renal cortex renal pelvis ureter urethra Übungsaufgabe Bitte an der richtigen Stelle einsetzen: Ureters | nephrons | infection | permeable | destroy | lithotripsy | red | glucose | excretory | women | dehydration | blood | pus | men | balance | pressure | albumin | stones | painful | metabolic | male | Urinarybladder | disorders | Kidneys | enter | Urethra | small | loop | Urination | ADH | The urinary System eliminates _ _ _ _ _ _ _ _ _ waste from the body maintains appropriate levels of water regulates the acid-base _ _ _ _ _ _ _ (pH), blood _ _ _ _ _ _ _ _ , and _ _ _ blood cell production.

The urinary System consists of only four organs: 1. _______ 2. _______ 3. _______ _______ 4. _______. 114 The organs are the same in both _ _ _ _ and female. Urine is formed by millions of _ _ _ _ _ _ _ _ located in the kidneys. The nephron has a portion shaped like a "C" (called the Bowman's capsule) where the water and waste is filtered from the _ _ _ _ _ . Molecules _ _ _ _ _ enough to pass through the glomerulus and the cells of the Bowman's capsule leave the blood and _ _ _ _ _ the renal tubule.

The kidneys process up to 150 liters of filtrate each day to create about 1,5 liters of urine. The ureters drain the urine from the kidney to the holding area—the bladder. The urethra carries the urine to the urinary meatus for excretion. _ _ _ _ _ _ _ _ _ (micturition, voiding) is controlled by an involuntary internal sphincter muscle and a voluntary external urethral sphincter. Urinary tract infections or UTIs affect _ _ _ _ _ 10 times more often than _ _ _ .

So ergeht es auch dem menschlichen Organismus: Ohne Sauerstoffzufuhr kein „Verbrennungsvorgang“ in der „Biomaschine“ Mensch. Der Atemapparat besteht aus all jenen Organen, die diesen Verbrennungsvorgang ermöglichen. Der Atemapparat führt dem Körper durch das Einatmen von Luft Sauerstoff (O2) zu und durch die Ausatmung Kohlendioxid (CO2) ab. Beim Atmungsvorgang unterscheiden wir zwischen der Inneren und der äußeren Atmung. Die Atmungsorgane der äußeren Atmung umfassen: die oberen Luftwege (Nase mit Nasennebenhöhlen, die mittleren Luftwege (Rachen) und die unteren Luftwegen (Kehlkopf, Luftröhre, Bronchien und Lunge) Die »äußere Atmung« wird gekennzeichnet durch die Tätigkeit der Lunge. Der Sauerstoff gelangt über die Atemwege in die Lunge. Hier diffundiert er aus der Atemluft ins Blut, gleichzeitig wird Kohlendioxid aus dem Blut an die Atemluft abgegeben. Der Gastransport zwischen Lunge und Körperzellen geschieht auf dem Blutweg. Im Gegensatz zur oben beschriebenen »äußeren Atmung« versteht man unter der »inneren Atmung« die Atmung der Körperzellen (Gewebeatmung), die mit Hilfe des Sauerstoffs in den Zellen abläuft. Im Rahmen der Stoffwechselvorgänge wird Energie „umgesetzt“. Zur Aufrechterhaltung der Lebensvorgänge benötigen alle Körperzellen ständig Sauerstoff bzw. Energie. Als Abfallprodukte entstehen Wasser und Kohlendioxid. Das Kohlendioxid wird dann im Rahmen der »äußeren Atmung« auf dem Blutweg zur Lunge transportiert und dort abgeatmet. Neben der Einteilung in obere, mittlere und untere Luftwege unterscheidet man auch die luftleitenden Atmungsorgane (z.B. Nase mit Nasennebenhöhlen, Rachen, Kehlkopf, Luftröhre und Bronchien ) von der dem Gasaustausch dienenden Lunge mit ihren Lungenbläschen (Alveolen). 117 Übersetzen Sie bitte den folgenden Text zum Themenbereich „Atmungssystem“ The Respiratory System The respiratory system maintains the exchange of oxygen and carbon dioxide in the lungs and tissues. It helps regulate the body's acid-base balance. The upper respiratory tract consists primarily of the nose, mouth,pharynx, and larynx. The upper respiratory system warms and humidifies inspired air, is responsible for taste, smell, and the chewing and swallowing of food. The air enters the body through the nostrils (nares). In theses nares, small hairs (vibrissae) filter out dust and large foreign particles. The air then passes into the two nasal passages, which are separated by the septum cartilage forms the anterior walls of the nasal passages . Conchae warm and humidify air before it passes into the nasopharynx. Four paranasal sinuses are located in the frontal, sphenoid, and maxillary bones. Sinuses provide speech resonance. The larynx contains the vocal cords and connects the pharynx with the trachea. Lower respiratory tract consists of the trachea, bronchi, and lungs The conducting airways contain the trachea and bronchi and hHelp facilitate gas exchange. The trachea extends from the cricoid cartilage at the top to the carina (also called the tracheal bifurcation). The trachea is protected by C-shaped cartilage rings that reinforces it and prevents it from collapsing. The primary bronchi begin at the carina. The right mainstem bronchus is shorter, wider, and more vertical than the left; supplies air to the right lung. The left mainstem bronchus delivers air to the left lung. As bronchi become smaller, they fast lose cartilage, then smooth muscle until, finally, the smallest bronchioles consist of just a single layer of epithelial cells Each bronchiole includes terminal bronchioles and the acinus.It is the chief respiratory unit for gas exchange. The respiratory bronchioles terminate in clusters of capillary-swathed alveoli called alveolar sacs. The alveoli are the site of gas exchange. 118 The tiny area between the visceral and parietal pleural layers is called pleural cavity. It contains a thin film of serous fluid. This fluid has two functions: 1. Lubricates the pleural surfaces so that they slide smoothly against each other as the lungs expand and contract 2. Creates a bond between the layers that causes the lungs to move with the chest wall during breathing. The area surrounded by the diaphragm (below), the scalene muscles and fasciae of the neck (above), and the ribs, intercostal muscles, vertebrae, sternum, and ligaments (around the circumference) is called thoracic cavity The Space between the lungs, the mediastinum, contains: - Heart and pericardium - Thoracic aorta - Pulmonary artery and veins - Venae cavae and azygos veins - Thymus, lymph nodes, and vessels - Trachea, esophagus, and thoracic duct - Vagus, cardiac, and phrenic nerves 119 Respiration The respiration is composed of two processes: 1. Inspiration—an active process 2. Expiration—a relatively passive process Both actions rely on respiratory muscle function and the effects of pressure differences in the lungs During normal respiration, the external intercostal muscles (located between and along the lower borders of the ribs) aid the diaphragm (major muscle of respiration). The diaphragm descends to lengthen the chest cavity, while the external intercostal muscles contract to expand the anteroposterior diameter This coordinated action causes inspiration. Rising of the diaphragm and relaxation of the intercostal muscles causes expiration Inspiration Exspiration 120 10 The Reproductive System In jeder Sekunde unseres Lebens entstehen Millionen neuer Zellen. Sie wachsen, vermehren sich und sterben wieder ab. Durch die sogenannte Fortpflanzung wird schließlich ein Organismus bzw. ein menschlicher Körper durch einen anderen ersetzt. Beim menschlichen Organismus geschieht die Fortpflanzung auf sexuellem Wege. Das neue Leben entsteht aus einer einzigen Eizelle (Ovum), die durch ein Spermium befruchtet wird und dadurch zur befruchteten Eizelle (= Zygote) wird. Die Produktion dieser Keimzellen und die Befruchtung übernehmen die männlichen und weiblichen Fortpflanzungsbzw. Geschlechtsorgane. Die Fortpflanzungsorgane gehören zum sogenannten Genitalsystem. Das Genitalsystem hat drei wesentliche Aufgaben: 1. Fortpflanzung 2. Bildung der Geschlechtshormone 3. beim Mann auch Harnweg Beim Genitalsystem unterscheiden wir zwischen den a) Primären Geschlechtsmerkmale (= innere + äußere Geschlechtsorgane) und b) Sekundären Geschlechtsmerkmale ( = Brüste, Achsel Schambehaarung Bartwuchs, Stimmbruch, Geschlechtsspezifisches Verhalten, Beckenentwicklung, Skelettbau usw.) Die inneren Geschlechtsorgane dienen der Produktion von Keimzellen und Sexualhormonen. Bei der Frau dienen die inneren Geschlechtsorgane zusätzlich der Versorgung und Geburt des Keimlings. Die äußeren Geschlechtsorgane dienen der geschlechtlichen Vereinigung (Koitus). Die weiblichen Geschlechtsorgane Zu den inneren Geschlechtsorganen der Frau gehören: die Eierstöcke (= Ovarien), die Eileiter (= Tubae uterinae), die Gebärmutter (= Uterus) und die Scheide Zu den äußeren Geschlechtsorganen, die in ihrer Gesamtheit als Vulva bezeichnet werden, gehören die großen Schamlippen und die kleinen Schamlippen, der Kitzler (= Clitoris) und die Vorhofdrüsen (Bartholin'sche Drüsen) 121 Die Ovarien sind paarige, etwa pflaumengroße Organe, in denen die weiblichen Keimzellen, die Eizellen, und die weiblichen Sexualhormone gebildet werden. Ähn-lich einem Trichter liegen ihnen die ebenfalls paarigen Eileiter an. Die Eileiter sind bleistiftdünne Muskelschläuche, die mit einem Flimmerepithel ausgekleidet sind und die die Eizellen zur Gebärmutter transportieren. Im Eileiter erfolgt gegebenenfalls die Befruchtung der Eizelle. Die Eileiter münden in die Gebärmutter. Sie ist ein birnenförmiges, muskulöses Hohlorgan und nimmt gegebenenfalls die befruchtete Eizelle auf. Außerdem beteiligt sich die Gebärmutter am Aufbau des Mutterkuchens und dient am Ende der Schwangerschaft durch Kontraktionen der Muskulatur (= Geburtswehen) der Austreibung des Kindes. An der Gebärmutter unterscheiden wir: den Gebärmutterkörper (= Corpus uteri) und den Gebärmutterhals (= Cervix uteri). Den Eingang zum Gebärmutterhals bezeichnet man als Muttermund (= Portio vaginalis). Die Wand der Gebärmutter besteht aus drei Schichten: Außen ist sie vom Bauchfell überzogen; diese Schicht heißt Perimetrium. Es folgt nach innen die glatte Muskulatur = Myometrium. Innen ist die Gebärmutter mit Schleimhaut = Endometrium ausgekleidet. Die Scheide (= Vagina) ist ein ca. 10 cm langer, mit Schleimhaut ausgekleideter Muskelschlauch, der in dem unteren Abschnitt durch eine ringförmige Hautfalte, das Jungfernhäutchen (= Hymen), teilweise verschlossen ist. Beim ersten Geschlechtsverkehr reißt dieses Häutchen ein (Defloration). Die Scheide ist das Kopulationsorgan der Frau. Sie nimmt die Samenzellen des Mannes auf, die dann selbständig durch die Gebärmutter in die Eileiter wandern müssen. Ein säurehaltiges Sekret, an dessen Bildung hier ansässige Bakterien - die sog. Scheidenflora - beteiligt sind, schützt die inneren Geschlechtsorgane vor aufsteigenden Krankheitskeimen. Die großen Schamlippen entsprechen dem Hodensack des Mannes; sie schützen den Scheidenvorhof. Die Clitoris und - in viel schwächerem Maße - die kleinen Schamlippen - sind sexuelle Reizorgane. Die Bartholin'schen Drüsen schließlich halten den Scheidenvorhof feucht. Die männlichen Geschlechtsorgane Die äußeren Geschlechtsorgane des Mannes sind der Penis mit Schwellkörpern, Vorhaut, Eichel und Harnsamenröhre . Zu den inneren männliche Geschlechtsorganen gehören die Geschlechtsdrüsen des Mannes (Hoden), die ableitenden Geschlechtswege (paarig: Nebenhoden, Samenleiter, Spritzgänge; unpaarig: Harn, Samenröhre) und die sogenannten akzessorische Geschlechtsdrüsen ( Bläschendrüsen, Bulbourethraldrüsen, Prostata). Die Hoden liegen im Hodensack. Sie sind die Keimdrüsen des Mannes. Sie sind etwa pflaumengroß, haben eine ovale Form und liegen in einer Hauttasche, dem Hodensack (Skrotum). Unmittelbar auf den Hoden sitzen die Nebenhoden (Epididymis). Die Nebenhoden (Epididymis) sind kleine Organe, die auf den Hoden sitzen und als Samenspeicher dienen. 122 Um die Nebenhoden vollständig zu leeren, bedarf es mehrerer aufeinanderfolgender Samenergüsse (Ejakulationen) im Zeitraum von 24 Stunden. Der Penis hängt vor dem Hodensack. Er ist ungefähr sechs bis zwölf Zentimeter lang und von Mann zu Mann unterschiedlich dick. Am Ende des Penis sitzt die Eichel (Glans penis). Die Eichel ist normalerweise von der Vorhaut (Praeputium) verdeckt. Viele Nervenendigungen in der Eichel machen sie zu einem sehr empfindlichen und auch sehr erregbaren Organ. Besonders am äußeren Rand ist die Eichel sehr sensibel. Unter der Vorhaut liegen kleine Drüsen, die ein weißliches Sekret produzieren. Dieses Sekret, Smegma genannt, sollte regelmäßig bei der Hygiene entfernt werden. Ist dies nicht möglich, weil sich die Vorhaut nicht zurückschieben lässt, liegt eine Vorhautverengung (Phimose) vor, die unter Umständen operiert werden muss. In manchen Ländern und in bestimmten Religionen wird die Vorhaut durch eine Beschneidung entfernt. Dies hat keine negativen Auswirkungen auf die sexuelle Funktion des Penis. Der Penis besitzt 3 Schwellkörper, in deren Mitte die Harnröhre verläuft. Durch diese tritt der Urin und beim Geschlechtsverkehr / Ejakulation das Ejakulat (Sperma) aus. Bei sexueller Erregung füllen sich die Schwellkörper mit Blut, wodurch sich der Penis aufrichtet, hart und groß wird. In erigiertem Zustand ist der mit Blut gefüllte Penis dann zwölf bis zwanzig Zentimeter groß. Er nimmt meistens sowohl im Durchmesser als auch in der Länge zu. Sperma ist die weißlich/gräuliche, kastanienartig riechende Samenflüssigkeit, die beim Samenerguss (Ejakulation) aus der Harnröhre (Urethra) austritt. Sperma besteht aus Spermien (Samenfäden oder Spermatozoen) sowie zum überwiegenden Anteil aus Flüssigkeiten verschiedener männlicher Drüsen. Normalerweise enthält das Sperma einige Millionen Spermien pro Milliliter. Prostata und Samenbläschen produzieren etwa 95 Prozent der Samenflüssigkeit, lediglich fünf Prozent kommen aus den Hoden. 123 Work with a partner Translate the sentences Dictate the sentences to each other. Determination of sex Whether a human being is female or male is already determined at the time of conception. All human cells have 23 pairs of chromosomes, one of these pairs being the sex chromosome. In women the sex chromosomes are an identical pair (XX), but in men one of the two is smaller (XY). When reduction division occurs in the germ cells of the ovaries and testes, the pairs are split. Thus all ova will have 22+X chromosomes, as will half the spermatozoa, but the other half will have 22 +Y, and when one of these unites with a 22 +X ovum a male embryo results. x x x x x y x y 124 The female reproductive system Organs Clitoris Labia majora Labia minora Description Function Rounded projection at the upper part of the pudendal cleft, sheathed by a prepuce Provides feeling of pleasure during sexual stimulation Two longitudinal folds of skin that extend from the mons pubis to the perineum; separated longitudinally by the pudendal cleft Form margins of pudendal cleft; enclose and protect other external reproductive organs Two longitudinal folds of skin medial to the labia majora; separated longitudinally by the vaginal vestibule Mammary glands Composed of lobes within the breasts Ovaries Primary sex organ; upper pelvic cavity an both lateral sides of uterus Form margins of vestibule; protect openings of vagina and urethra Produce and secrete milk for nourishment of an infant Produce of ova and female sex hormones Open-ended tubes that extend from the ovaries to the uterus Convey ova toward uterus; site of fertilization; convey developing blastocyst to uterus Uterus Hollow organ shaped like an inverted pear; maintained in position within the pelvic cavity by muscles and ligaments Site of implantation; sustains life of embryo and fetus during pregnancy; plays active role in parturition Vagina Hollow organ positioned between the urinary bladder and urethra anteriorly and the rectum posteriorly Conveys uterine secretion to outside of body; receives erect penis and semen during coitus; passageway for fetus during parturition Subcutaneous within the wall of the vaginal opening Secrete lubricating fluid into the vestibule and vaginal opening during coitus Uterine tubes (fallopian tubes) Vestibular glands 125 Identify the structures of the female reproductive system in the illustration below 9 8 1 7 6 2 5 4 3 126 Nr.

The male reproductive system The purpose of the organs of the male reproductive system is to perform the following functions: 1. to produce, maintain and transport sperm (the male reproductive cells) and protective fluid (semen) 2. to discharge sperm within the female reproductive tract during sex 3. to produce and secrete male sex hormones responsible for maintaining the male reproductive system Unlike the female reproductive system, most of the male reproductive system is located outside of the body. These external structures include a) the penis, b) the scrotum, and c) the testis. Penis Testis Scrotum 129 The Penis The penis is the male organ used in sexual intercourse. It has 3 parts: 1. the root, which attaches to the wall of the abdomen; 2. the body, or shaft; and the glans, which is the cone-shaped part at the end of the penis. 3. The glans, also called the head of the penis, is covered with a loose layer of skin called foreskin. The opening of the urethra, the tube that transports semen and urine, is at the tip of the penis. The penis also contains a number of sensitive nerve endings. The body of the penis consists of 3 circular shaped chambers. These chambers are made up of special, sponge-like tissue. This tissue fill with blood when the man is sexually aroused. As the penis fills with blood, it becomes rigid and erect, which allows for penetration during sexual intercourse. Semen, which contains sperm (reproductive cells), is expelled (ejaculated) through the end of the penis when the man reaches sexual climax (orgasm). The Scrotum The scrotum is the loose pouch-like sac of skin that hangs behind the penis. It contains the testicles (also called testes), as well as many nerves and blood vessels. The scrotum acts as a "climate control system" for the testes. For normal sperm development, the testes must be at a temperature slightly cooler than body temperature. Special muscles in the wall of the scrotum allow it to contract and relax, moving the testicles closer to the body for warmth or farther away from the body to cool the temperature. The testes The testes (testicles) are oval organs about the size of large olives that lie in the scrotum, secured at either end by a structure called the spermatic cord. Most men have two testes. The testes produce and store millions of tiny sperm cells. The testicles are also part of the endocrine system because they produce hormones, including testosterone. Testosterone is a major part of puberty in men, and as a man makes his way through puberty, his testicles produce more and more of it. Testosterone is the hormone that causes guys to develop deeper voices, bigger muscles, and body and facial hair, and it also stimulates the production of sperm. 130 Lückentext: Bitte an der richtigen Stelle einsetzen: sperm | fluid | epididymis | penis | blood | penis | body | sperm | pubic | scrotum | external | behind | walnut | urethra | responsible | prostate gland | ejaculatory ducts | tubes | vas deferens | manufacture | The Male Reproductive System The _ _ _ _ _ _ _ _ genitalia are those parts of the reproductive tract that are visible in the _ _ _ _ _ region, which in a male comprise the _ _ _ _ _ _ _ and the _ _ _ _ _ . The scrotum is a loose bag of skin and connective tissue that holds the paired testes suspended within it. The penis consists mainly of erectile tissue, which becomes engorged with _____ during sexual arousal. The _ _ _ _ _ _ _ , through which urine and _ _ _ _ _ pass, runs through the center of the Penis. About the size of a large _ _ _ _ _ _ and surrounded by a tough fibrous capsule, the _ _ _ _ _ _ _ _ _ _ _ _ _ lies just under the bladder, encircling the upper part of the urethra. The gland is closely attached to the base of the bladder, with its rounded anterior (front) surface lying just _ _ _ _ _ _ the pubic bone. The prostate gland forms a vital part of the male reproductive system because it provides an enzyme-rich _ _ _ _ _ that helps to activate _ _ _ _ _ and forms up to one-third of the total volume of seminal fluid. This fluid is secreted by cells in the prostate gland and passed through _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ , which open into the urethra. The structures that make up the male reproductive tract are _ _ _ _ _ _ _ _ _ _ _ for the production of sperm and seminal fluid and their passage out of the body. The paired testes lie suspended in the scrotum outside the _ _ _ _ , and they are responsible for the _ _ _ _ _ _ _ _ _ _ _ of sperm, which then travel through a complex network of _ _ _ _ _ and ducts. The coiled _ _ _ _ _ _ _ _ _ _ receives the sperm from the testis, from where it passes to the _ _ _ _ _ _ _ _ _ _ _ , a long muscular tube that passes through two glands, the seminal vesicle and the prostate gland, both of which add fluid to the sperm.

Alles was wir riechen, hören, sehen, fühlen, schmecken usw. wird als „Informationspaket“ in elektrische Impulse umgewandelt und über die Nervenbahnen zur Verarbeitung zum Gehirn weitergeleitet. Umgekehrt werden die Befehle und Anweisungen vom Gehirn als elektrische Signale (= Nervenimpulse) an den Körper weitergeleitet. Zum Nervensystem gehören u.a. Gehirn und Rückenmark sowie das periphere Nervensystem, das alle Nerven umfasst, die vom Zentralnervensystem - kurz ZNS - ausgehen. Zum Schutz des Nervensystems vor Beschädigungen sind der Schädel und die Wirbelsäule da! Gehirn und Rückenmark bilden zusammen das Zentralnervensystem - die zentrale Schaltstelle des gesamten Nervensystems. Das wichtigste Organ des Zentralnervensystems ist das Gehirn, eine Kontrollinstanz aus über zehn Milliarden Nervenzellen, von denen jede einzelne wiederum mit bis zu 10.000 anderen Nervenzellen verbunden ist. Die verschiedenen Regionen des Gehirns übernehmen jeweils bestimmte Funktionen. Das Gehirn ist für sämtliche unserer Aktivitäten verantwortlich, sowohl bewusste als auch unbewusste. Es kann als "Sitz der Persönlichkeit" eines Menschen bezeichnet werden - mit all seinen Gefühlen, Gedanken und Fähigkeiten. Drei Häute umgeben das Gehirn schützend: 1. die harte Hirnhaut, 2. die Spinnwebhaut und 3. die innere Hirnhaut. Entzündete Hirnhäute sind die Ursache der Krankheit Meningitis. Man unterscheidet bei den Gehirnregionen Kleinhirn, Hirnstamm, Großhirn, Großhirnrinde, Zwischenhirn, Thalamus und Hypothalamus. 138 Zentralnervensystem (ZNS) u. Peripheres Nervensystem (PNS) Anatomisch (=strukturell) sind Zentralnervensystem (ZNS) und peripheres Nervensystem (PNS) zu trennen. Zum ZNS werden Gehirn und Rückenmark gerechnet, die verbleibenden, dem Gehirn und Rückenmark entspringenden Nerven(-wurzeln) mit ihrer Fortsetzung in Form einzelner Nerven bilden das PNS. Nach funktionellen Gesichtspunkten können wir das Nervensystem in das sogenannte sensomotorische System, welches im weitesten Sinne für den "Bezug zur Umwelt", und das vegetative Nervensystem, welches für die Aufrechterhaltng von Körperfunktionen zuständig ist, einteilen. Das Sensomotorisches System Das sensomotorische System besteht aus einem sensibel-sensorischen Teil, welcher Sinneseindrücke von der Umwelt empfängt und sie zur zentralen Verarbeitung weiterleitet und aus einem motorischen Teil, welcher für die Bewegungsäußerungen des Körpers zuständig ist. Zum sensorischen Bereich des Nervensystems zählen verschiedene Rezeptoren , welche jeweils für unterschiedliche Sinneseindrücke zuständig sind wie z.B. für Temperatur, Schmerz, Berührung, aber auch Geruch, Geschmack, Bewegung und Lage des Körpers und seiner Gliedmaßen, Hören und Sehen. Als Rezeptoren dienen spezifsche Strukturen am Ende von Nervenzellfortsätzen. Sie sind in der Lage, wie zum Teil auch freie Nervenendigungen, bestimmte Reize in Nervenaktionspotentiale ( = elektrische Signale, elektrische Impulse) umzuwandeln. Die wichtigste Aufgabe des motorischen Systems ist es,Muskelbewegungen durchzuführen. Das vegetative Nervensystem Während das sensibel-sensorische Nervensystem Zustände der Umwelt übermittelt und das motorische Nervensystem dem Verhalten in der Umwelt dient, werden ebenfalls beständig Informationen über Funktionszustände des Körpers, des sogenannten Inneren Milieus registriert, verarbeitet und in Reaktionen umgesetzt. Einen großen Teil dieser Aufgaben übernimmt das vegetative Nervensystem (VNS). Auch das vegetative Nervensystem lässt sich in einen peripheren und einen zentralen Anteil gliedern. Das vegetative Nervensystem innerviert die glatte Muskulatur aller Organe, das Herz und die Drüsen. Nach funktionellen Kriterien lassen sich zwei komplementäre Anteile des vegetativen Nervensystems ausmachen, den Sympathicus und den Parasympathicus. Im Bereich des Rückenmarkes auf Höhe vom BWS und LWS –Bereich finden wir die Nervenzellen des vegetativen Nervensystems in den sogenannten Seitenhörnern der grauen Substanz. Ihre Fortsätze verlassen das Rückenmark über die vorderen Wurzeln 139 um zum Teil gleich darauf in beidseits des Rückenmarks gelegene Zellansammlungen einzumünden. Diese Zellansammlungen (Ganglien) finden sich auf der Höhe des jeweiligen Rückenmarkssegmentes und sind untereinander nach oben und unten verbunden, so dass rechts und links vom Rückenmark jeweils ein perlschnurartiges Gebilde entsteht, der Grenzstrang. Viele innere Organe werden sowohl vom Sympathikus als auch vom Parasympathikus innerviert. Beide wirken auf das jeweilige Organ antagonistisch. Eine Reizung des Sympathicus führt z.B. zur Zunahme von Herzfrequenz und Herzschlagvolumen, zur Abnahme der Darmtätigkeit und zur Erschlaffung der Gallenblase, während der Parasympathicus Herfrequenz und Schlagvolumen verringert, die Darmmotilität anregt und eine Kontraktion der Gallenblase auslöst.

The nervous system 1 The nervous system is divided into the peripheral and central nervous System. The brain and spinal cord make up the central nervous System. 1: _____________________________ 2 2: _____________________________ 3: _____________________________ 3 The central nervous System is divided into the voluntary System and the autonomic or involuntary System. The autonomic nervous System provides a rapid response to a threat where we may need to be able to run or defend ourselves. The brain is the command center of the body. It receives information from the world, processes it, and sends out a response. It is composed of two hemispheres of convoluted tissue. The right hemisphere controls the left side of the body and the left hemisphere controls the right side of the body. The two hemispheres are joined by tissue called the corpus callosum. There are four main parts to the brain: the cerebrum, 141 cerebellum, brain stem, and diencephalon. The cerebrum is primarily for thinking and emotion. Both the right and left side can be broken down into frontal lobe, temporal lobe, occipital lobe, and parietal lobe. Each lobe manages special functions as listed in the table below: Lobes Special Functions Frontal Emotions and personality Parietal Math and logic Temporal Processing spoken word Occipital Processing visual information 142 The autonomic System is made up of the sympathetic and parasympathetic Systems. The sympathetic nervous System is responsible for a release of glucose from the liver, increased heart rate, increased blood pressure, increased respiration, and decreased genitourinary action. These physiological changes help humans to "fight or flight" in a dangerous Situation. 143 The parasympathetic nervous System creates the reverse responses to help slow the body down. 144 A Comparison of Sympathetic and Parasympathetic Activity Organ or gland Heart Skin Skeletal muscles Sympathetic stimulation Parasympathetic stimulation Increased rate rate and Decreased rate and strength of contraction strength of contraction Vasoconstriction (adrenergic), vasodilation, blushing (cholinergic) Vasoconstriction (adrenergic), vasodilation (cholinergic) None None Dilation in a few Blood vessels Mostly constriction Viscera Vasoconstriction (adrenergic) Vasodilatation Reproductive organs Vasodilation (cholinergic) Vasodilation organs(e.g., penis) Contraction and erection of Hair None hair Bronchioles Dilation GI tract Decreased activity and tone Gallbladder and ducts Inhibition Stimulation Anal sphincter Closing stimulated Closing inhibited Urinary bladder Muscle tone aided Contraction Ciliary muscle of eye Relaxation (for far vision) Contraction (for near vision) Iris of eye Dilation of pupil Constriction of pupil Sweat glands Stimulation of secretion (cholinergic) None Nasal, lacrimal, salivary, gastric, Vasoconstriction and inhibited secretion Pancreatic islets Decreased secretion of insulin Liver Stimulation of glycogen hydrolysis with release of glucose into blood 145 Constriction Increased activity (peristalsis) and tone Vasodilation and stimulated secretion Increased secretion None 12 The Sensory Organs Alle Organe( z. B. Auge, Ohr usw.) mit deren Hilfe wir Informationen aus unserer Umwelt aufnehmen, sind Sinnesorgane und gehören zum sensorischen System des Körpers. Unser sensorische System ist ein Teil des Nervensystems, das für die Verarbeitung der sensorischen Informationen verantwortlich ist. Bestandteile eines sensorischen Systems sind z.B. die sensorischen Empfänger (= Rezeptoren), sensorische Nervenbahnen und die entsprechenden Gehirnregionen, die die ankommenden elektrischen Signale und Informatioen entsprechend weiter verarbeiten. Die Reize, die bei den Rezeptoren die elektrischen Impulse auslösen, können von unterschiedlicher Art sein. Die folgende Tabelle zeigt die Reizart und das dazugehörende Sinnesorgan: Reizart Sinnesorgan Auge mit seinen lichtempflindlichen Lichtreize Zellen (Stäbchen und Zapfen) Haarzellen in der Hörschnecke Schallreize im Innenohr Kälte- und Wärmerezeptoren Temperaturreize in der Haut und Schleimhaut Druck- und Tastrezeptoren Druck- und Tastreize in der Haut und Schleimhaut Riechsinneszellen im Riechfeld Chemische Reize der Nase usw. und empfindliche Zellen auf der Zunge Schmerzreize Schmerzrezeptoren Reize, die von der Schwerkraft Lage- und Drehsinnrezeptoren ausgeübt werden im Innenohr 146 Das Auge Der Augapfel liegt geschützt in einem Fettpolster in der knöchernen Augenhöhle. Seine Wand wird durch verschiedene Häute gebildet. Außen liegt die weiße undurchsichtige Lederhaut. Diese geht vorn in die durchsichtige Hornhaut über. Die mittlere Haut ist die Aderhaut. Sie ist reich an Blutgefäßen. Im vorderen Bereich geht die Aderhaut über in a) den Strahlenkörper und b) die Regenbogenhaut. Strahlenkörper Im Strahlenkörper befindet sich glatte Muskulatur. Am Strahlenkörper ist der Aufhängeapparat der Linse befestigt. Durch Veränderung der Muskelkontraktion im Strahlenkörper wird die Linse über den Aufhängeapparat stärker oder schwächer gewölbt. Regenbogenhaut (Iris) Die Iris enthält ebenfalls ringförmig angeordnete glatte Muskulatur. Dadurch kann die Pupille je nach Lichteinfall enger oder weiter gestellt werden. Netzhaut Die Netzhaut bildet die innerste Haut des Augapfels. In der Netzhaut liegen die Sinneszellen, die aus den "Stäbchen" und den "Zäpfchen" bestehen. Die Stäbchen dienen dem "Schwarzweißehen" und die Zäpfchen dem "Farbsehen". Weitere Teile des Augapfels sind: Linse Die Linse befindet sich zwischen der Iris und dem Glaskörper. Sie ist durch den Aufhängeapparat am Strahlenkörper befestigt. Sie kann für das Nahsehen stärker gewölbt und für das Fernsehen stärker abgeflacht werden (unterschiedliche Brechkraft der Lichtstrahlen bzw. unterschiedliche Brennweite der Linse). Die Verstellung erfolgt über die "Strahlenbänder" durch die unterschiedlich starke Kontraktion der Muskulatur im Strahlenkörper. Der Glaskörper besteht aus einer gallertartigen durchsichtigen Masse und füllt den Raum hinter der Linse aus. Der blinde Fleck befindet sich am Augenhintergrund an der Stelle, an der der Sehnerv aus dem Augapfel heraustritt. in diesem Bereich befinden sich keine Sinneszellen. Der gelbe Fleck ist die Stelle des schärfsten Sehens. In diesem Bereich befinden sich besonders zahlreiche Zäpfchen (Sinneszellen für das Farbsehen). 147 Augenwasser befindet sich in der vorderen Augenkammer (zwischen Hornhaut und Iris) und in der hinteren Augenkammer (zwischen Iris und Linse). Es wird von bestimmten Zellen des Strahlenkörpers ständig neu gebildet und wird über den sogenannten Schlemm' schen Kanal abgeleitet. Bei einer Störung der Ableitung entsteht ein zu hoher Augeninnendruck. Der Sehsinn Die durch das Sehloch (die Pupille) einfallenden Lichtstrahlen werden im normalen Auge durch die Linse so gebrochen, dass sie sich auf der Netzhaut im Augenhintergrund zu einem scharfen Bild vereinigen. Von den lichtempfindlichen Sinneszellen der Netzhaut werden die Impulse über die Sehbahn dem Gehirn übermittelt und treten als Sehwahrnehmung ins Bewusstsein. Beim normalsichtigen Auge treten die Lichtstrahlen durch das Sehloch ein und werden durch die Linse so gebrochen, dass sie ihren Brennpunkt genau auf der Netzhaut im Augenhintergrund haben. Die Pupille regelt durch Enger- oder Weiterstellung die Menge des einfallenden Lichtes (Schutz vor grellem Licht usw.). Die Bewegung jedes Augapfels erfolgt über sechs Augenmuskeln (4 gerade Augenmuskeln, 2 schräge Augenmuskeln). (Schielen kann durch falsche Längen der Augenmuskeln verursacht werden). Tränendrüsen Die Tränendrüsen liegen im oberen äußeren Winkel der Augenhöhlen (zum oberen äußeren Lidrand hin). Die Tränenflüssigkeit, die durch den Lidschlag verteilt wird, dient zur Befeuchtung der Hornhaut, die nicht austrocknen darf. Überschüssige Tränenflüssigkeit wird aber den Tränennasengang zur Nase hin abgeleitet Die Augenlider dienen zur Befeuchtung und zum Schutz der Hornhaut. bei Berührung der Hornhaut durch einen Fremdkörper schließen sich die Lider durch Reflex sofort. Die Innenseiten der Lider sind mit der zarten Bindehaut ausgekleidet, die auf den Augapfel übergeht. Die Wimpern und die Augenbrauen sollen das Auge vor Staub, Fremdkörpern und herabrinnendem Schweiß schützen. 148 Work with a partner Translate the sentences Dictate the sentences to each other. The eye 149 Retina Photorezeptor neurons (rod and cone cells) light waves Bipolar neurons Ganglion neurons The eyes are specialized organs of sight designed to detect patterns of light. Like the camera, the eye collects and focuses light on to a sensitive surface. Its lens are transparent, yellowish and gelatinous. Relaxation of these ligaments is produced by contraction of the ciliary muscle at the back of the iris — this allows the lens to bulge and makes nearby objects come into focus. The pupil is the aperture of the iris, which is an automatic diaphragm opening and closing in response to changes of lighting. Behind the lens the eyeball is filled with a sticky, jelly-like substance, at the back of which is the retina. The retina is made up of three layers of nerve cells. In order in which they conduct impulses, they are the rod and the cone cells, bipolar neurons and ganglion neurons. The rods and cones are the extensions of small neurons, and they convert light into nerve impulses which are passed to the brain along the fibres of the optic nerve. Where the optic nerve leaves the eye there are no receptors : this "blind spot" is slightly off the axis of vision. Fovea centralis Retina Lens Light waves Cornea Optic nerve Sclera Vitreous cavity "Blind spot" The centre of the retina possesses only cones connected to nerve fibres in a 1 :1 ratio. The proportion of rods increases away from the centre and receptors converge onto fewer fibres. Since rods work at low light intensity (they contain an easily bleached pigment — rhodopsin — derived from vitamin A) the periphery of the retina is adapted for sensitivity in dim light, the centre for detailed, daylight vision. Blind spot Fovea centralis Retina 150 Übersetzen Sie bitte die folgenden Termini bzw. den englischen Fachtext!

Das äußere Ohr Das äußere Ohr besteht aus der Ohrmuschel und dem leicht gebogenen äußeren Gehörgang. Letzterer wird auch als «Ohrkanal» bezeichnet. Er weist eine durchschnittliche Länge von 23 Millimetern und einen Durchmesser von 6 bis 8 Millimetern auf. In seinem äußeren Drittel befinden sich die Ceruminaldrüsen. Diese produzieren das Ohrenschmalz, dessen Aufgabe es ist, das Ohr vor eindringenden Schmutzpartikeln zu schützen. Das Mittelohr Zwischen dem Gehörgang und dem Mittelohr befindet sich das Trommelfell, welches einen Durchmesser von ca. 10 Millimetern aufweist und als Empfänger der Schallwellen dient. Mit dem Trommelfell fest verbunden ist der Hammer, ein Knöchelchen, das zusammen mit dem Amboss und dem Steigbügel für eine Übertragung der Schallwellen zum Innenohr sorgt. Die Gehörknöchelchen sind winzig klein; der Steigbügel als deren kleinstes weist knapp die Größe eines halben Reiskorns auf. Zwischen dem Mittelohr und dem Rachenraum besteht eine direkte Verbindung – die Eustachischen Röhre – die für einen permanenten Druckausgleich im Mittelohr sorgt Das Innenohr Die Fußplatte des Steigbügels wiederum ist mit der Ohrschnecke (= Cochlea) – verbunden. Dabei handelt es sich um eine spiralenförmig gewundene Röhre von ca. 32 mm Länge und zweieinhalb Windungen Steigung. Die Röhre wird durch zwei Membrane in drei «Schläuche» unterteilt, die mit zwei unterschiedlichen Flüssigkeiten (= Endolymphe und Perilymphe) gefüllt sind. 153 Das Cortische Organ Auf der in der Mitte der Röhre verlaufenden Basilarmembran befindet sich das Cortische Organ mit seinen rund 20 000 Haarzellen, die in einer inneren und drei äußeren Reihen angeordnet und in 24 Gruppen unterteilt sind. Jede dieser Haarzellen-Gruppen spricht auf die Töne einer bestimmten Frequenz – bzw. eines bestimmten Frequenzband-Abschnitts – an. Töne hoher Frequenzen werden dabei im vorderen, solche tieferer Frequenz im hinteren Teil der Cochlea wahrgenommen. Die Haarzellen Die Haarzellen – deren Aufgabe es ist, mechanische Reize in bioelektrische Impulse umzuwandeln – sind äußerst sensible und verletzliche Organe, die durch Überstrapazierung schwer geschädigt werden können. Die meisten Fälle von Schwerhörigkeit sind auf eine Schädigung der Haarzellen durch zu laute und zu lange Lärm-Einwirkung auf das Ohr zurückzuführen. Der Hörnerv Die von den Haarzellen produzierten und weiter gegebenen bioelektrischen Impulse werden vom Hörnerv aufgenommen – einer komplexen, aus rund 30 000 Fasern bestehenden Nervenbahn, die das Innenohr mit dem Hörzentrum im Gehirn verbindet. Der Gleichgewichtsapparat Zum Innenohr gehört auch der Gleichgewichtsapparat, der aus zwei kleinen Bläschen – dem Sacculus und dem Utriculus – sowie drei Bogengängen besteht. Sacculus und Utriculus enthalten winzige Kalksteinchen, deren Position sich – bedingt durch die Schwerkraft der Erde – analog zur Lage des Kopfes verändert. Die Bogengänge wiederum reagieren auf FlüssigkeitsBewegungen, die durch die Drehbewegungen des Kopfes ausgelöst werden. 154 Work with a partner Translate the sentences Dictate the sentences to each other. The ears and hearing Sounds are a series of invisible compression waves that moves through air or other materials. Although it is commonly associated in air, sound will readily travel through many materials such as water and steel. All sound waves are created by the vibration of some object. Because sound is the vibration of matter, it does not travel through a vacuum or in outer space. All sound waves are detected when they cause a detector to vibrate. Our eardrum vibrates from sound waves to allow us to sense them. Sound has the standard characteristics of any waveform. But sound waves different than light waves. The visible light waves, the invisible ultraviolet (UV) light and the x-rays are electromagnetic radiation. They are completely different than sound, which is vibration of matter. Electromagnetic waves are related to electrical and magnetic fields and readily travel through space. The back-and-forth vibration of an object creates the compression waves of sound. This is different than the up and down or transverse motion of a electromagnetic wave. The ear The ear is the organ of hearing and equilibrium. It consists of three principal regions: 1. The outer ear 2. The middle ear 3. The inner ear The ears provide us with two different senses: a) hearing and b) balance Sound waves detected by the ears provide essential information about our external surroundings and allows us to communicate, such as speech and music. 155 In addition, our ears contribute to our sense of balance, the largely unconscious understanding of the body´s orientation in space that allows us to maintain an upright posture and move without falling over. 1 2 3 4 5 6 7 11 10 9 8 Identify the structures of the ear auditory ossicles Gehörknöchelchen auditory tube Eustachische Röhre, Ohrtrompete auricle Ohrmuschel cochlea Hörschnecke cochlear window ovales Fenster external auditory canal äußerer Gehörgang middle ear Mittelohr semicircular canals Bogengänge tympanic cavity Paukenhöhle tympanic membrane Trommelfell vestibulocochlear nerve Hör-Gleichgewichtsnerv 156 Work with a partner Complete the sentences using the nouns in the box.

The external ear consists of the visible part (the pinna), which is made up of skin and _ _ _ _ _ _ _ _ _ , and the external auditory meatus, which channels _ _ _ _ _ waves toward the middle ear. Inside the external meatus are tiny _ _ _ _ _ and ceruminous glands that secrete _ _ _ _ _ _ _ (wax). This combination of wax and hairs helps prevent dust and foreign bodies from _ _ _ _ _ _ _ _ the ear. At the inner end of the meatus is the tympanic membrane, or _ _ _ _ _ _ _ , which vibrates in response to sound waves and marks the _ _ _ _ _ _ between the external and middle ear. Beyond the tympanic membrane (eardrum) is the middle ear, an air-filled cavity that helps transmit sound to the inner ear and is connected to the _ _ _ _ _ _ _ (throat) via the auditory (eustachian) tube. Within the middle ear are three tiny bones called _ _ _ _ _ _ _ _ that are linked together in such a way that movements of the eardrum are transmitted across them to the oval window at the entrance to the inner ear. The first bone, the _ _ _ _ _ _ _ , is attached to the inner surface of the eardrum at one end, and to the second bone, the _ _ _ _ _ , at the other. The stapes is the third ossicle and is connected both to the incus and to the oval window. All three ossicles are held in place by tiny ligaments. The inner ear contains the organs of balance and hearing.
