Apocrine glands, which begin to function at puberty under hormonal influence, seem not to be useful in thermoregulation. Where would we find these glands in the human body?

Explanation:

They are located at the armpits, anogenital regions,ear canal,eye lids, areola and nipples of the breast.

The Apocrine gland  has a  direct link to the hair follicle.it is made up of clusters of secretory tubules, which emptied to the hair follicles through the excretory duct. This gland secretions is not continuous, but in periodic fashion. The components of the secretion are protein,lipids, steroids. The secretion is usually odorless and Oily in nature. However  this changed when mixed with bacterial or germs on exposure to the skin surface.

At the base of the hair follicles are the sebacious glands which produced sebum. Therefore as the apocrine secretion leaves the secretory ducts, they are mixed with sebum to reach the epidermal surface of the skin.
