What are the four main functions of 1. protection
skin? 2. absorption
3. secretion
4. perception
What are the three layers of the skin? 1. epidermis
2. dermis
3. subcutaneous
What are the types of epidermal 1. hair
appendages? 2. sebaceous and sweat glands
3. nails
,What are the layers of epidermis? inner basal cell layer - forms new skin cells
outer horny cell layer - dead keratinized cells that
determine skin color
What are the types of tissue present in collagen (connective tissue)
the dermis? elastic tissue
What is the purpose of the dermis? inner supportive layer
What are the two layers of the dermis? papillary
reticular
What is contained in the dermis? (6 1. blood vessels
items) 2. nerves
3. sebaceous glands
4. lymphatic vessels
5. hair follicles
6. sweat glands
What makes up the subcutaneous fat, loose connective tissue
layer?
What are the 5 functions of the 1. provides insulation
subcutaneous layer ? 2. caloric reserve storage
3. stores fat for energy
4. cushioning
5. contributes to skin mobility
What is the function of hair? 1. protects specific body areas
2. provides insulation
3. enables sensory communication to nervous system
4. contributes to gender identification
What is vellus hair? fine, short, hypopigmented
located throughout most of body
,What is terminal hair? darker, coarser
located on scalp, brows, eyelids
postpubertal-axillae, perineum, legs, chest and
abdomen (men)
What are the 9 functions of the skin? 1. protection
2. prevents penetration
3. perception
4. thermoregulation
5. identification
6. communication
7. wound repair
8. absorption and excretion
9. production of vitamin D
What are three developmental -increased permeability --> increased susceptibility to
considerations of newborn skin? fluid loss
-decreased thermoregulation (skin cannot protect
against cold-unable to contract and shiver, subQ layer
is inefficient)
-eccrine glands not active until first few months of life
What are the developmental increased apocrine gland secretion (heat and
considerations of pubescent skin? emotional stimuli) --> BODY ODOR!!!
increased sebaceous glands --> acne development
, What are the developmental -increased metabolism
considerations of skin during -increased sebaceous gland secretion
pregnancy? -striae gravidarum (stretch marks)
-chloasma (irregular brown patch of
hyperpigmentation on face, "mask of pregnancy")
-linea nigra (increased pigmentation midline
abdomen)
-vascular spiders
What are the developmental -decreased elasticity with aging
considerations of geriatric skin? -decreased sebum = DRYNESS
-decreased perspiration
-decreased melanin=grey hair
-increased sunlight sensitivity
-thicker/more brittle nails
What is erythema toxicum? -common rash, "flea bite" rash
-occurs in first 3-4 days of life
-on cheeks, trunk, chest, back and buttocks
-unknown cause
-no treatment needed
What is Curtis Marmorata? -transient mottling in trunk and extremities in response
to cooler room temperatures
