Terms. An apocrine sweat gland (/ˈæpəkrən, -ˌkraɪn, -ˌkriːn/; from Greek apo– "away" and krinein "to separate")[5][6] is composed of a coiled secretory portion located at the junction of the dermis and subcutaneous fat, from which a straight portion inserts and secretes into the infundibular portion of the hair follicle. The part of the hair that you see outside the body is the follicle. As your temperature rises during activity, your body signals blood. 1. secretory cells 2. The rule of nines is used to determine the ________. Therefore, the eccrine glands are of interest in most psychophysiology and biofeedback applications. These secretions acquire a distinctive odor by the action of bacteria on the skin surface. Sweat produced in the apocrine sweat glands is a fatty substance (earwax, breast milk, for example). Myoepithelial cells 3. duct cells. Secretory cells. The secretions of apocrine sweat glands contain more fat and protein than do the secretions of eccrine sweat glands. Hidradenitis suppurativa (hi-drad-uh-NIE-tis sup-yoo-ruh-TIE-vuh) is a skin condition that causes small, painful lumps to form under the skin. apocrine gland: [ gland ] an aggregation of cells specialized to secrete or excrete materials not related to their ordinary metabolic needs. Privacy [9] In humans, the apocrine glands in this region are the most developed (with the most complex glomeruli). The other, apocrine glands, develop around hair follicles [source: Britannica]. Correct! THE TYPES OF APOCRINE SWEAT GLAND CARCINOMAS. Sweat glands, classified as simple, coiled tubular glands, exist as two types in the human, eccrine and apocrine. The apocrine sweat glands primarily respond to thermal regulation and the eccrine sweat glands tend to respond to emotionality or arousal level. [16][8] The secretory tubules of apocrine glands are single layered, but unlike the eccrine secretory tubules, contain only a single type of ductal epithelial cell,[17] varying in diameter according to their location, and sometimes branching off into multiple ducts. The key difference between merocrine and apocrine sweat glands is that merocrine sweat glands excrete sweat directly onto the surface of the skin opening out through the sweat pore while apocrine sweat glands secrete sweat into the pilary canal of the hair follicle without opening directly onto the surface of the skin. The condition mostly affects areas where the skin rubs together, such as the armpits, groin, buttocks and breasts.Hidradenitis suppurativa tends to start after puberty. stratum lucidum. Any of the sweat glands in the axillae and pubic region that open into hair follicles rather than directly onto the surface of the skin as do eccrine sweat glands. The products of the bacterial degradation of this type of sweat are responsible for the body odor. [23] More bacteria (especially corynebacteria) leads to stronger odor. In humans, there are two main types of sweat glands: eccrine and apocrine. Eccrine glands occur over most of your body and open directly onto the surface of your skin. In its morphology, the apocrine gland is large and spongy. Your skin has two types of sweat glands: eccrine and apocrine. apocrine The sweat glands that are located in the Correct! Some lesions are multilobulated and … Apocrine glands, located in the armpits and genital area, secrete a thick fluid that releases an odor when it mixes with bacteria on the skin’s surface. [18] Men have more apocrine sweat glands than women in all axillary regions. Emotional stress stimulates contraction of the gland, expelling its contents.

The apocrine glands are mainly found in areolar of the breast, armpits, the area between anus and genitals, the eyelids and the ear. [14] The gland is large and spongy, located in the subcutaneous fat deep in the dermis,[9][15] and has a larger overall structure and lumen diameter than the eccrine sweat gland. [23] Unlike eccrine sweat glands, which secrete continuously, the apocrine glands secrete in periodic spurts. Hormonal changes in puberty hair follicle than that produced by the merocrine mode the.
