What is the term used for the fine, downy hair on the skin?

Terminal hair
Lanugo
Vellus
Club hair

The correct answer is: Vellus

The term that refers to the fine, downy hair on the skin is indeed vellus. Vellus hair is characterized by being soft, thin, and typically unpigmented, making it less noticeable than other types of hair. This type of hair is found over much of the body, particularly in areas like the face and arms, and is especially common in children before they go through puberty. Terminal hair, in contrast, is thicker, darker, and longer, commonly found on the scalp, armpits, and pubic areas after puberty. Lanugo refers to the fine hair that covers the body of fetus and newborns, which is typically shed shortly after birth. Club hair is a term used to describe hair that is in the transitional phase leading to shedding and is not related to the fine hair on the skin. Therefore, vellus is the correct term for the fine, downy hair found on the body.
