question 24 (1 point)
what is the outermost layer of hair?
o a hair medulla
b hair follicle
o c hair cortex

Explanation:

• Question 22: The anagen phase is the active growth phase of hair follicles where new hair is produced. Telogen is the resting phase, catagen is the transitional phase, and "genesis" is not a standard hair - growth - phase term in this context.
• Question 23: Lanugo hair (fine hair on fetuses), vellus hair (fine, short body hair), and terminal hair (coarse, long hair like scalp hair) are main types. Anagen is a hair - growth phase, not a type of body hair.
• Question 24: The hair cuticle is the outermost layer of the hair shaft. The hair medulla is the innermost layer, the hair follicle is the structure that houses the hair root, and the hair cortex is the middle layer.

Answer:

• Question 22: d. anagen
• Question 23: c. anagen hair
• Question 24: d. hair cuticle
