Question

multiple choice question
which term refers to the swelling at the lower end of the hair root?

follicle

bulb

matrix

shaft

Explanation:

• A follicle is the structure that encloses the hair root, not the swelling at its end.
• The hair bulb is the rounded, swollen structure at the lower end of the hair root, which contains the actively dividing cells that produce hair.
• The matrix is the inner layer of the hair bulb, not the swelling itself.
• The shaft is the visible, above-surface part of the hair, unrelated to the root's lower end.

Answer:

bulb
