MICROANATOMY

Detailed explanation-1: -Apocrine sweat glands start to function at puberty under the stimulation of sex hormones. They are associated with hair follicles in the groin and axillary region. The viscous, protein-rich product is initially odorless but may develop an odor after exposure to bacteria.

Detailed explanation-2: -Eccrine sweat glands occur over most of the body and open directly onto the skin’s surface. Apocrine glands open into the hair follicle, leading to the surface of the skin. Apocrine glands develop in areas with many hair follicles, such as on the scalp, armpits and groin.

Detailed explanation-3: -Sebaceous glands are holocrine glands, and sweat glands (both eccrine and apocrine ones) are merocrine glands.

Detailed explanation-4: -Eccrine glands are found all over the body and secrete a thin, watery sweat that cools the skin. Apocrine glands are found in the armpits and perineal areas, and are attached to hair follicles. The latter secrete a thicker sweat, which is acted on by bacteria to produce the all-too-familiar “sweat smell."
