Explanation:

Question 64

The arrector pili muscle is responsible for causing goose bumps (pilorection) in response to cold or fear. The other options (angled, secretory, absorption muscles) are not related to this function.

The dermis is the inner layer of the skin, also called derma corium, cutis, or true skin. The papillary is a layer within the dermis, dermal is an adjective, and the epidermis is the outer layer.

Alopecia universalis is the complete loss of all body hair. Alopecia areata is patchy hair loss, alopecia totalis is total scalp hair loss, and androgenic alopecia is hair loss related to hormones (male - pattern or female - pattern baldness).

Answer:

b. arrector pili muscle
