GENERAL HISTOLOGY

Detailed explanation-1: -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-2: -Sweat glands are coiled tubular structures vital for regulating human body temperature. Humans have three different types of sweat glands: eccrine, apocrine, and apoeccrine. Eccrine sweat glands are abundantly distributed all over the skin and mainly secrete water and electrolytes through the surface of the skin.

Detailed explanation-3: -Apocrine glands produce viscous, lipid-rich sweat, which is also comprised of proteins, sugars, and ammonia [21, 23]. The function of apocrine glands in many species is generally regarded as scent glands involved in production of pheromones (body odor), although this social/sexual function is rudimentary in humans.
