Thin layers that divide the epidermis
strata
Has a framework of connective tissue and contains many bliid vessels, nerve endings, and glands; true skin
dermis
Two layers of the skin
Dermis
Epidermis
Deepest layer of epidermis where new epidermal cells are produced (2 names)
Stratum Basale
Stratum Germinativum
Protein that thickens and protects the skin
Keratin
Protective epidermal layer that is deeper in thick skin than in thin skin
Stratum Corneum
A dark pigment that colors the skin an dprotects it from the harmful rays of sunlight
Melanin
The cells that produce pigment
Melanocytes
Extentions of the dermis that project up into the epidermis
Dermal papillae
Layer that conects the skin to the surface muscles; consists of loose connective tissue and large amounts of adipose tissue
Subcutaneous layer
Saclike structure that secrete sebum to lubricate the skin and hair; open into the hair follicle
Sebaceous gland
Oily secretion produced by the sebaceous gland
Sebum
"Cheesy varnish"; babies are born covered in this sebaceous secretion
Vernix caseosa
Modified sebaceous glands that are associated with the eyelashes and produce a secretion that lubricates the eyes
Meibomian glands
A sac of accumulated sebum that forms whena sebaceous gland becomes blocked
Sebaceous cyst
Coiled, tubelike structure located in the dermis and the subcutaneous tissue; sweat glands
Sudoriferous glands
Sweat glands that regulate body temperature and vent directly to the surface of the skin through a pore
Eccrine sweat gland
Sweat glands that release some cellular material along with its secretions; located mainly in armpits and groin
Apocrine sweat gland
Thin band of involuntary muscle attacthed to the hair follicle
Arrector pili
Functions of the skin

A rough, jagged wound made by tearing the skin
Laceration
A sore associated with disintegration and death of tissue
Ulcer
a crack in the skin
Fissure
A wound or injury
Trama
Type of burn that involves the epodermis and perhaps a portion of the dermis; tissue is reddened and may blister
Superficial partial-thickness
Type of burn that involves the epidermis and portions of the dermis; tissue is blistered and broken with a weeping surface
Deep partial-thickness
Type of burn that involves the full skin and sometimes subcutaneous tissue and underlying tissue; tissue is broken, dry and pale, or charred
Full-thickness
Determining the amount of the body surface involved in a burn by assigning percentages in multiples of nine
Rule of nines
More accurate determination of the amount of the body surface involved in a burn; divides the body into small areas and estimates the proportion of BSA each contributes
Lund and Browder method
Wound healing is affected by:
Nutrition
Infection
Blood supply
Age
Fibrous connective tissue that replaces normal tissue destroyed by injury or disease
Scar (cicatrix)
General term referring to any skin disease
Dermatosis
Inflammation of the skin
Dermatitis
Skin disease characterized by intense inthcing and skin inflammation; areas show redness, blisters, scaling
Apoptic dermatitis
Chronic overgrowth of the wpodermis leading to large, sharply outlined, red, flat areas covered with silvery scales
Psoriasis
Malignant tumor of melanocytes; originates in a nevus
Melanoma
Mole or birthmark
Nevus
Disease of the sebaceous glands connected with hair follicles
Acne
An acute contagious disease of staphylococcal or strepococcal origin; forms blisterlike lesions that fill with pus
Impetigo
