What is the term for a small, cone-shaped elevation at the base of the hair follicle filled with blood vessels?

The correct term for a small, cone-shaped elevation at the base of the hair follicle that is filled with blood vessels is the dermal papillae. This structure plays a critical role in hair growth and development. The dermal papillae is comprised of a small, mound-like formation that provides the necessary nutrients and blood supply to the hair follicle, promoting healthy hair production. This structure also contains nerve endings that can detect changes around the hair, contributing to sensations such as touch.

In the context of hair anatomy, the dermal papillae is essential for the hair's growth cycle, supporting the growth of the hair bulb, where the new hair cells are generated. The health of the dermal papillae is crucial for maintaining the overall health and viability of hair follicles. Understanding its function can help emphasize the importance of proper blood circulation and nutrient delivery in hair health.
