Question: 1 / 400

What are the three layers of the internal epidermal root sheath called?

Henley’s layer, Huxley’s layer, and the cuticle

The correct answer identifies the three layers of the internal epidermal root sheath as Henley’s layer, Huxley’s layer, and the cuticle. Each of these layers plays a specific role in the structure and function of hair follicles.

Henley’s layer, the outermost of the three, provides a barrier and support for the inner structures. Huxley’s layer functions primarily in aiding the formation of the hair and anchors the hair shaft while contributing to the overall structure of the hair follicle. Finally, the cuticle, which is the innermost layer, has a protective function that shields the hair shaft from damage and helps in the overall health of the hair.

These layers are essential in understanding hair anatomy and how each component contributes to the hair growth process, which is crucial for professionals in fields like dermatology and cosmetology.
