Which glands are sac-like and attached to hair follicles?

• A. Sebaceous
• B. Eccrine
• C. Aporcrine
• D. Endocrine

Answer: (A)

Sebaceous glands are indeed sac-like structures that are attached to hair follicles. These glands are responsible for producing sebum, an oily substance that helps to lubricate and protect the skin and hair. The sebum produced by the sebaceous glands is released into the hair follicle and subsequently onto the skin’s surface, which aids in maintaining moisture and preventing dryness. In contrast, eccrine glands are sweat glands that are distributed throughout the body and are not associated with hair follicles. They play a significant role in thermoregulation and are primarily responsible for producing a watery sweat that helps cool the body. Apocrine glands, on the other hand, are also sweat glands but are located primarily in areas such as the underarms and groin, and they secrete a thicker sweat that becomes odoriferous once it comes into contact with bacteria on the skin. Endocrine glands, unlike the other options, are ductless glands that release hormones directly into the bloodstream and have no direct association with hair follicles. Understanding the function and structure of sebaceous glands helps clarify their role in skin health, particularly their connection to hair follicles and the maintenance of skin moisture.
