Which gland type is associated with hair follicles and sebum production?

• A. Eccrine glands
• B. Sebaceous glands
• C. Ceruminous glands
• D. Apocrine glands

Answer: (B)

Sebaceous glands sit in the dermis and are connected to hair follicles, producing sebum, an oily substance that coats both hair and skin. Their ducts open into the hair follicle, so sebum goes right where hair grows, keeping hair moisturized and the skin flexible. This linkage to hair follicles and the production of sebum is what distinguishes them from other gland types. Eccrine glands, by contrast, release watery sweat directly onto the skin surface and aren’t tied to hair follicles. Ceruminous glands are specialized for earwax in the ear canal, and apocrine glands, while associated with hair in certain areas, secrete a different kind of sweat with odor-producing potential rather than sebum production.
