But these hormonal changes also serve as irritants for the sebaceous glands or the skin's oil glands and irritate them, leading to acne. (bizrahmed.com)
Apocrine17
In humans, apocrine sweat glands are found only in certain locations of the body: the axillae (armpits), areola and nipples of the breast, ear canal, eyelids, wings of the nostril, perineal region, and some parts of the external genitalia. (wikipedia.org)
Most non-primate mammals, however, have apocrine sweat glands over the greater part of their body. (wikipedia.org)
Domestic animals such as dogs and cats have apocrine glands at each hair follicle and even in their urinary system, but eccrine glands only in foot pads and snout. (wikipedia.org)
Their apocrine glands, like those in humans, produce an odorless, oily, opaque secretion that gains its characteristic odor upon bacterial decomposition. (wikipedia.org)
The secretory tubules of apocrine glands are single layered, but unlike the eccrine secretory tubules, contain only a single type of ductal epithelial cell, varying in diameter according to their location, and sometimes branching off into multiple ducts. (wikipedia.org)
For most mammals, however, apocrine sweat glands secrete an oily (and eventually smelly) compound that acts as a pheromone, territorial marker, and warning signal. (wikipedia.org)
Being sensitive to adrenaline, apocrine sweat glands are involved in emotional sweating in humans (induced by anxiety, stress, fear, sexual stimulation, and pain). (wikipedia.org)
The apocrine gland secretes an oily fluid with proteins and lipids that is odorless before microbial activity. (wikipedia.org)
Apocrine sweat glands were originally thought to use only apocrine secretion: vesicles pinch off from the secretory cells, then degrade in the secretory lumen, releasing their product. (wikipedia.org)
The apocrine sweat is cloudy, viscous, initially odorless, and at a pH of 6-7.5. (wikipedia.org)
The "axillary organs", limited regions with equal numbers of apocrine and eccrine sweat glands, only exist in humans, gorillas, and chimpanzees. (wikipedia.org)
In humans, the apocrine glands in this region are the most developed (with the most complex glomeruli). (wikipedia.org)
Hidradenitis suppurativa is a disorder of the terminal follicular epithelium in the apocrine gland-bearing skin. (medscape.com)
Hormonal changes1
Oil glands are more minor in children, but growth factors and hormonal changes tend to enlarge their size. (bizrahmed.com)
Acne1
This might help clean the skin pores as well as the openings of the sweat and sebum glands while keeping away acne and other skin diseases. (organicfacts.net)
