Which gland is considered primarily active during puberty due to hormonal changes?

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

Answer: (C)

The apocrine glands are primarily activated during puberty as a result of hormonal changes in the body. These glands, located mainly in the armpits and groin area, become more active due to the influence of sex hormones such as testosterone and estrogen. The hormonal surge during puberty is responsible for stimulating apocrine glands to secrete their viscous and odorous sweat, which is often associated with body odor.

In contrast, eccrine glands, which are responsible for regulating body temperature through sweat, are active from birth and their secretion does not change significantly during puberty. Sebaceous glands, which produce oil to lubricate the skin and hair, are also influenced by hormones, but their activation occurs earlier in adolescence rather than being exclusively tied to puberty. Saying "all glands" suggests that all types of glands undergo significant changes during puberty, which is not accurate since each type serves distinct functions at different stages of development. Hence, apocrine glands stand out as the primary glands sensitive to the hormonal shifts occurring at puberty.
