What term describes the hairs associated with eyelashes?

The term that describes the hairs associated with eyelashes is "Cilia." Cilia refers specifically to the short, fine hairs that are found on the edges of the eyelids, which help protect the eyes from debris and serve an important role in sensory perception. These hairs contribute to the eyelashes' primary function of shielding the eyes, as well as enhancing the aesthetic appearance of the eyes.

Vellus hair, on the other hand, refers to the fine, light-colored hair that is usually found all over the body. Lanugo is the fine, soft hair that covers a fetus in the womb and is typically shed before or shortly after birth. Terminal hair is coarser, thicker hair that is often found on the scalp, face, and body areas such as the armpits and groin, and is usually associated with puberty and hormonal changes.

Understanding these definitions helps clarify why "Cilia" is the appropriate term for the hairs associated with eyelashes, as it specifically denotes that particular type of hair.
