Integumentary System Overview
2
(cont’
(cont’d.)
The integumentary system includes the skin
and its accessory structures:
Hair
Nails
Various glands
Various muscles
Various nerves
The skin is divided
into two distinct
regions:
Epidermis
Dermis
From Jarvis C: Physical exam and health assessment, ed 4,
Philadelphia, 2004, Saunders.

(cont’
(cont’d.)
(cont’
(cont’d.)
The epidermis is the most superficial skin
layer and contains:
Keratinocytes (skin cells)
Melanocytes (contribute to skin color)
Nails
Pores (allow passage for hair and glands)
The dermis is beneath the epidermis and
contains:
Blood vessels
Sensory nerve receptors
Collagen
Elastin

Subcutaneous layer:
Skin functions:
Protection
Absorption
Sensory reception
Temperature regulation
Vitamin D production
Beneath the dermis
Also known as superficial fascia or hypodermis
Not part of the skin but anchors skin to underlying
tissues and organs
7
(cont’
(cont’d.)
(cont’
(cont’d.)
Hairs:
grow from follicles
protect scalp, eyes, nostrils, ears
have touch receptors (activated by hair movement)
arrector pili muscle (erect hairs)
Nails:
are plates of tightly packed epidermis cells
help when grasping and manipulating objects
protect ends of fingers and toes
enable scratching to remove irritants

Front view and cross section of a nail:
Skin lesions
Defined as any deviation from the norm
Two categories
• Primary: variation in skin color or texture (ex. freckle,
blister)
• Secondary: develops from a primary lesion, disease
progression, or external forces (ex. ulcer, scar)
Differentiations not always clear
