| Question | Answer |
|---|---|
| the study of the skin and skin disorders | dermatolody |
| contains the stratum germinativum and the stratum corneum | epidermis |
| contains adipose tissue | subcutaneous layer |
| layer of skin that contains the blood vessels, nerves, and sensory recepters | dermis |
| epidermal layer that forms the bathtub ring | stratum corneum |
| layer underneath the epidermis | dermis |
| layer of epidermis that continuously produces millions of cells every day | stratum germinativum |
| a protein in the skin that flattens, hardens, and makes the skin water-resistant | keratin |
| surface layer of the epidermis that makes up most of the epidermal thickness | stratum corneum |
| layer that insulates the body from extreme temperature changes and anchors the skin to the underlying structures | subcutaneous layer |
| hypodermis | subcutaneous layer |
| another name for the skin | integument |
| desquamation and exfoliation refer to this epidermal layer | stratum germinativum |
| another name for the cutaneous membrane | integument |
| this epidermal layer forms corns and calluses | stratum corneum |
| oil glands | sebaceous |
| a blackhead is formed when this gland becomes blocked by accumulated oil and debris | sebaceous |
| a pimple is formed when the sebum of this blocked gland becomes infected | sebaceous |
| sweat glands that cause body odor and are responsible for sex attractants in animals | apocrine |
| babies born with a "cream cheese-like" covering called vernix caseosa that is secreted by these glands | sebaceous |
| these glands and the apocrine glands are classified as sudoriferous glands | eccrine |
| sweat glands that are usually associated with hair follicles and are found in the axillary and genital areas | apocrine |
| sweat glands that respond to emotional stress and also become activated when a person is sexually aroused | apocrine |
| sweat glands that play the most important role in temperature regulation | eccrine |
| milk-secreting glands that are classified as modified sweat glands | mammary |
| modified sweat glands that secrete earwax | ceruminous |
| pigment that darkens the skin; the pigment-secreting cells are stimulated by ultraviolet radiation | melanin |
| condition in which no melanin is secreted | albinism |
| loss of pigment in the skin that creates patches of white skin | vitiligo |
| melanin is concentrated in local areas; benign | freckles |
| highly malignant form of skin cancer that arises from melanocytes | melanoma |
| substance that gives persons of Asian descent a slight yellowish skin coloring | carotene |
| caused by vasodilation of the dermal blood vessels | flushing |
| caused by vasoconstriction of the dermal blood vessels | pallor |
| condition in which the skin has a bluish tint caused by a diminished amount of oxygen in the blood | cyanosis |
| color change caused by hypoxemia | cyanosis |
| hair loss | alopecia |
| yellowing of the skin caused by an accumulation of bilirubin in the skin | jaundice |
| described as ashen | pallor |
| temperature within the cranial, thoracic, and abdominal cavities | core temperature |
| mechanisms whereby the body balances heat production and heat loss | thermoregulation |
| about 500 mL/day of water is lost through the skin | insensible perspiration |
| eccrine glandes are responsible fro this type of perspiration | sensible perspiration |
| heat production due to continuous contractions of skeletal muscles when cold | shivering thermogenesis |
| evaporation, conduction, convection, and radiation | modes of heat loss |
| heat production caused by the metabolism of brown fat in the neonate | nonshivering thermogenesis |
| temperature of the surface areas such as the skin, mouth, and axilla | shell temperature |
| thermostat of the body | hypothalamus |
