Which of the following is NOT one of the three main structures of the hair root?

Explanation:
Understanding hair anatomy helps: the hair root is the part of the hair located below the skin inside the hair follicle. Within the root, you have the hair bulb at the base, where cells divide to form new hair, the follicle itself that surrounds the root, and the dermal papilla at the very bottom that provides nourishment. The hair shaft is the portion that extends above the skin surface and is what you see outside the skin. Since the shaft is the visible part, not the portion still embedded in the follicle, it’s not considered part of the hair root.
