Key terms
Collagen- An insoluble fibrous protein of vertebrates that is the chief constituent of the fibrils of
connective tissue (as in skin and tendons) and of the organic substance of bones.
Connective Tissue- Animal tissue that functions mainly to bind and support other tissues, having a
sparse population of cells scattered through an extracellular matrix.
Dermis- The sensitive vascular inner mesodermic layer of the skin.
Elastin- A protein that is similar to collagen and is the chief constituent of elastic fibers.
Endorphin- A hormone produced in the brain and anterior pituitary that inhibits pain perception .
Epidermis- The outer nonsensitive and nonvascular layer of the skin of a vertebrate that overlies the
dermis. Contains 4 different protective cells found in 5 layers. (keratinocytes, melanocytes, Langerhans
cells, and stratum corneum.
Epithelium- A membranous cellular tissue that covers a free surface or lines a tube or cavity of an animal
body and serves especially to enclose and protect the other parts of the body, to produce secretions and
excretions, and to function in assimilation.
Exocrine gland- A gland (as a sweat gland, a salivary gland, or a kidney) that releases a secretion external
to or at the surface of an organ by means of a canal or duct.
First-degree burn- A mild burn characterized by heat, pain, and reddening of the burned surface but not
exhibiting blistering or charring of tissues.
Keratin- Any of various sulfur-containing fibrous proteins that form the chemical basis of epidermal
tissues (as hair and nails) and are typically not digested by enzymes of the gastrointestinal tract.
Melanin- Any of various black, dark brown, reddish brown, or yellow pigments of animal or plant
structures (as in skin and hair).
Pain- Basic bodily sensation that is induced by a noxious stimulus, is received by naked nerve endings, is
characterized by physical discomfort (as pricking, throbbing, or aching), and typically leads to evasive
action.
Sebaceous gland- Any of the small sacculated glands lodged in the substance of the derma, usually
opening into the hair follicles, and secreting an oily or greasy material composed in great part of fat
which softens and lubricates the hair and skin.
Second-degree burn- A burn marked by pain, blistering, and superficial destruction of dermis with
edema and hyperemia of the tissues beneath the burn.
Third-degree burn- Severe burn characterized by destruction of the skin through the depth of the dermis
and possibly into underlying tissues, loss of fluid, and sometimes shock.
