What type of hair is known as eyebrow hair?

1. Cilia

2. Barb

3. Supercilia

4. Villus

The correct answer is: Supercilia

The hair known as eyebrow hair is called supercilia. This term specifically refers to the fine, short hairs that make up the eyebrows, playing a crucial role in both aesthetics and function. Eyebrow hair helps to accentuate the eyes and can influence facial expressions. Additionally, supercilia can help to divert moisture away from the eyes, which is a practical biological function. While the other terms refer to different types of hair or structures, they do not specifically designate eyebrow hair. For instance, cilia are microscopic hair-like structures involved in movement or sensory functions in various organisms, while barb refers to projections found on feathers and other anatomical structures. Villus hair, on the other hand, is the fine, soft hair that covers much of the human body but is not specific to the eyebrow region. Thus, the term supercilia is the accurate designation for eyebrow hair in this context.
