1. The skin repairs surface wounds by:
a. exaggerating cell replacement.
b. excreting lactic acid.
c. producing vitamins.
d. providing a mechanical barrier.
ANS: A
The skin’s tissue cells have a rapid rate of turnover and constant renewal, thereby enabling the skin to repair damaged surfaces.

2. The adipose tissue in the hypodermis serves to:
a. provide sensory input.
b. generate heat and insulate.
c. create tensile strength.
d. secrete collagen.
ANS: B
The hypodermis layer consists of adipose tissue that serves to generate heat and provide insulation, shock absorption, and a reserve of calories.

3. Sweat glands, hair, and nails are all formed from:
a. basement membranes under cellular strata.
b. closely packed squamous cells.
c. invaginations of epidermis into dermis.
d. papillae that penetrate the epidermis.

4. The secretory activity of the sebaceous glands is stimulated by:
a. body heat.
b. ambient temperature.
c. sex hormones.
d. dietary protein.
a. body heat.
b. ambient temperature.
c. sex hormones.
d. dietary protein.
ANS: C
The sebaceous glands, when stimulated by the sex hormones, produce a lipid-rich substance that keeps the skin moist.
