What term refers to the part of the hair that is beneath the scalp?

• A. Follicle
• B. Root
• C. Shaft
• D. Bulb

Answer: (B)

The term that refers to the part of the hair that is beneath the scalp is "root." The root of the hair is the portion that anchors the hair strand into the scalp and includes the lower part of the hair follicle. It is involved in the growth process, where cells in the bulb divide and push older cells outward, which then form the visible hair shaft. In contrast, the follicle encompasses the entire structure that contains the root, including the skin surrounding it, while the hair shaft refers to the visible part of the hair that extends above the scalp. The bulb is the rounded part at the base of the hair that contains the actively dividing cells essential for hair growth, but it does not encompass the entire hair section that is anchored beneath the scalp. Thus, defining the part of the hair that lies beneath the scalp specifically points to the root.
