Which part of the hair is the portion that extends beyond the skin surface?

Follicle
Shaft
Bulb
Root

The correct answer is: Shaft

The shaft of the hair is the portion that extends beyond the skin surface. This part is visible and is what people typically refer to when talking about hair. It plays a significant role in the aesthetics and styling of hair, as it is the part that can be cut, colored, or styled in various ways. In contrast, the follicle is a structure within the skin that anchors the hair and is not visible above the surface. The bulb is the rounded part of the hair located at the base of the follicle and is responsible for starting the hair growth process, while the root refers to the part of the hair that is below the surface of the skin, where it is embedded in the follicle. Thus, the shaft is unique in its position as the only part of the hair that protrudes outwards, giving it its external appearance.
