Small hairs that make up eyebrows and eyelashes are called what?

• A. Cilia
• B. Canthus
• C. Adnexa oculi
• D. Tarsus

Answer: (A)

Fine hairs on the face, including eyebrows and eyelashes, are called cilia. Cilia are small hair-like projections, and eyelashes are a classic example of them. Eyebrows are made of hair as well, so they share this same term. The other terms refer to different parts of eye anatomy: the canthus is the corner where the eyelids meet; adnexa oculi denotes the surrounding eye structures like the eyelids and lacrimal apparatus in general; and the tarsus is the thick connective tissue plate inside the eyelids that helps give them form.
