Pilosebaceous unit components?

Pilosebaceous unit components?

• A. Hair Follicle and Sebaceous Gland
• B. Eccrine gland
• C. Sweat gland
• D. Blood vessels

Answer: (A)

The pilosebaceous unit centers on the hair follicle and its associated sebaceous gland, often with the arrector pili muscle forming part of the same complex. The hair follicle is the structure that generates and houses the hair shaft, while the sebaceous gland sits adjacent to it and secretes sebum into the follicle to lubricate hair and skin. The eccrine (sweat) glands and other sweat glands are separate glands that open to the skin surface and are not part of this unit, and blood vessels, while nourishing the follicle and gland, are not glandular components of the pilosebaceous unit. So the combination that represents the pilosebaceous unit is the hair follicle and sebaceous gland.
