Integumentary System Review

Layer of translucent cells, absent in thin skin

stratum lucidum

Strata containing all or mostly dead cells

stratum corneum

Dermal layer responsible for fingerprints

papillary layer

vascular region

Dermis as a whole

Actively mitotic epidermal region, the deepest epidermal layer

stratum basale

cells are flat, dead "bags" of keratin

stratum corneum

site of elastic and collagen fibers

Dermis as a whole

general site of melanin formation

Stratum Basale

major skin area where derivatives (nail and hair) reside

dermis as a whole

Largely adipose tissue; anchors the skin to underlying tissues

hypodermis

the stratum germinativum

stratum basale

Epidermal layer where most melanocytes are found

stratum basale

Cells of this layer contain keratohyalin and lamellated granules

stratum granulosum

epidermal layer where most melanocytes are found

stratum basale

cells of this layer contain keratohyalin and lamellated granules

stratum granulosm

accounts for the bulk of epidermal thickness

stratum spinosm

when tanned, becomes leather; provides mechanical strength to skin

epidermis, specifically stratum corneum

epidermal layer containing the "oldest cells"

stratum corneum

name four factors that can cause hair loss and hair thinning other than nutritional or circulatory factors

1. hormonal imbalances

2. physical or emotional stress

3. genetics

4. autoimmune conditions

their mixture are an oily mixture of lipids, cholesterol, and cell fragments

sebaceous glands

functionally, these are merocrine glands

sweat glands (eccrine)

the less numerous variety of perspiration gland, their secretion (often milky in appearance) contains proteins and other substances that favor bacterial growth

sweat glands (apocrine)

their ducts open to the external environment via a pore

sweat glands (eccrine)

these glands are found everywhere on the body except the palms of the hands and soles of the feet

sebaceous glands

their secretions contain bacterial substances

sebaceous glands

they became more active at puberty under the influence of androgens

sweat glands (apocrine)

their secretions, when oxidized, are seen on the skin surface as a blackhead

sebaceous glands

the ceruminous glands that produce earwax are a modification of this gland variety

sweat glands (apocrine)

these glands are involved in thermoregulation

sweat glands (eccrine)

full thickness burn, epidermal and dermal layer destroyed, skin is blanched

third degree

blisters form

second degree

epidermal damage, redness, and some usually brief pain

first degree

epidermal and some dermal damage, pain, regeneration is possible

second degree

regeneration impossible, requires grafting

third degree

pain is absent because nerve endings in the area are destroyed

third degree

what is the importance of the rules of nines in the treatment of burn patients

It provides a quick method to estimate the total body surface area affected by the burns
