What is the name of the tube-like depression in the skin that contains the hair root?

Explanation:
The tube-like depression in the skin that contains the hair root is the hair follicle. It functions as a tunnel that extends from the skin surface into the dermis, housing the hair root and its growth region at the base. The deepest part, the hair bulb, sits inside the follicle and receives nutrients from the dermal papilla to fuel growth. The sebaceous gland links to the follicle to secrete oil, helping lubricate the hair, but it is not the tube that contains the root. So the hair follicle is the structure described.
