GENERAL HISTOLOGY

Detailed explanation-1: -Apocrine sweat glands are most active in times of stress and sexual excitement. In mammals (including humans), apocrine sweat contains pheromone-like compounds to attract other organisms within their species. Study of human sweat has revealed differences between men and women in apocrine secretions and bacteria.

Detailed explanation-2: -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.

Detailed explanation-3: -Answer and Explanation: Option C is correct. Apocrine sweat glands have limited distribution and are predominant in axillary and genital areas.

Detailed explanation-4: -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. Eccrine sweat glands are involved in hyperhidrosis, though apocrine glands may play a role as well.

Detailed explanation-5: -The apocrine glands secrete a viscous, oily substance, that is yellow in color, and has an acrid odor. This secretion is produced in response to the presence of bacterial decomposition.
