| Question | |
|---|---|
| ABCDEs of melanoma | asymmetry, border, color, diameter, evolving |
| acne | an inflammatory disease involving the sebaceous glands of the skin |
| adipocyte | fat cell |
| albinism | an inherited inability to produce melanin |
| apocrine glands | sweat glands in the pubic and underarm areas that secrete thicker sweat, produce odor when come in contact with bacteria on the skin |
| arch | a fingerprint pattern in which the ridge pattern originates from one side of the print and leaves the other side |
| arrector pili | a smooth muscle attached to hair follicles that causes "goose bumps" to appear on the skin when contracted |
| carotene | orange-yellow skin pigment |
| cutaneous membrane | the skin, composed of stratified squamous epithelium and dense connective tissue |
| defensins | antibacterial enzymes found on the skin |
| dendritic cells | specialized white blood cells that patrol the skin for infections |
| dermis | second layer of skin, holding blood vessels, nerve endings, sweat glands, and hair follicles |
| epidermis | most superficial layer of the skin |
| hypodermis | also known as the subcutaneous layer, deep to the dermis |
| keratin | hard, waterproof protein found in the epidermis, hair, and nails |
| keratinocytes | most abundant epidermal cells, they function mainly to produce keratin |
| loop | a fingerprint pattern in which the ridge pattern flows inward and returns in the direction of the origin |
| melanin | dark brown to black skin pigment |
| melanocytes | cells that produce melanin |
| melanoma | most serious form of skin cancer, metastasizes quickly |
| merocrine (eccrine) glands | produce watery sweat, used for cooling the body |
| metastasis | the spread of cancer cells beyond their original site |
| papillary layer | outer layer of the dermis, directly beneath the epidermis |
| pigment | chemical compound that absorbs light, producing color |
| reticular layer | deeper layer of the dermis |
| sebaceous glands | oil glands of the skin connected to hair follicles |
| sebum | oily substance secreted by the sebaceous glands |
| SPF | sun protection factor, multiply this number times the minutes it would take to burn without sunblock to calculate total protection |
| stem cells | unspecialized cells that divide to create new skin cells |
| stratum basale (germinativum) | base layer of skin, one cell layer, mitotic layer |
| stratum corneum | the most superficial layer of the epidermis consisting of dead cells |
| stratum granulosum | a layer of the epidermis that marks the transition between the deeper, metabolically active strata and the dead cells of the more superficial strata |
| stratum spinosum | spiny layer just above the stratum basale |
| subcutaneous layer | layer below the dermis containing adipose tissue |
| tactile cells | sensory touch receptors |
| thick skin | skin of the palms and soles which consists of five layers |
| thin skin | skin found everywhere except the palms and soles |
| UV radiation | energy from the sun |
| vasconstriction | a decrease in the diameter of the superficial blood vessels |
| vasodilation | an increase in the diameter of superficial blood vessels |
| vitamin D | produced in the skin by exposure to sunlight |
| whorl | a fingerprint pattern that resembles a bull's-eye |
