Which fact best describes apocrine glands?

• A. They are located in the pubic and underarm areas and secrete thicker sweat with odor
• B. They produce the primary watery sweat for thermoregulation
• C. They are destroyed in acne
• D. They are found in the brain

Answer: (A)

Apocrine glands are a type of sweat gland that work with hair follicles in specific body areas. They’re primarily found in the underarm and pubic regions. The secretions they produce are thicker and contain more lipids and proteins than the watery sweat produced by other glands. When bacteria on the skin break down this thicker sweat, it can produce body odor. These glands respond to hormonal signals and typically become active at puberty, which also helps explain their characteristic presence in these regions. In contrast, the watery sweat that helps cool the body comes from eccrine glands, not apocrine glands, and acne involves sebaceous glands rather than apocrine glands. The brain isn’t a site for apocrine sweat production either. So the description of location and the thicker, odor-causing secretion aligns with what apocrine glands are.
