GENERAL HISTOLOGY

Detailed explanation-1: -Apocrine sweat glands are located primarily in the axilla, breasts, face, scalp, and the perineum [21, 22]. As shown in Figure 1, these glands differ from eccrine glands in that they are larger and open into hair follicles instead of onto the skin surface [12].

Detailed explanation-2: -Apocrine glands are found predominantly in the anogenital and axillary regions, but are also located in the external auditory meatus (ceruminous glands), the eyelid (Moll gland), and within the areola. They are derived from the epidermis, and develop as an outgrowth of the follicular epithelium.

Detailed explanation-3: -Regarding the location where their ducts release their product, the ducts of sebaceous glands, in most cases, and apocrine sweat glands excrete their products into the hair follicle canal, and the eccrine sweat glands excrete directly onto the skin surface.
