Eccrine sweat glands are found in virtually all skin, with the highest density in the palms of the hands, and soles of the feet, and on the head, but much less on the torso and the extremities. In other mammals, they are relatively sparse, being found mainly on hairless areas such as foot pads.
The eccrine sweat glands are distributed over much of the body and are responsible for secreting the watery, brackish sweat most often triggered by excessive body temperature. Apocrine sweat glands are restricted to the armpits and a few other areas of the body and produce an odorless, oily, opaque secretion which then gains its characteristic ...
Peyer's patches (or glands) ileum, lymphatic glands Pineal gland: brain: melatonin: 32 Prostate: surrounds the urethra just below the urinary bladder: tubulo-alveolar 33 Pyloric glands: antrum of the pylorus, stomach: mucous, gastrin: simple branched tubular 34 Sebaceous gland: skin: sebum acinar - branched 35 Skene's gland, lesser vestibular ...
Sudomotor function refers to the autonomic nervous system control of sweat gland activity in response to various environmental and individual factors. Sweat production is a vital thermoregulatory mechanism used by the body to prevent heat-related illness as the evaporation of sweat is the body’s most effective method of heat reduction and the only cooling method available when the air ...
Eccrine sweat glands are everywhere except the lips, ear canal, foreskin, glans penis, labia minora, clitoral hood, and clitoris. They are ten times smaller than apocrine sweat glands, do not extend as deeply into the dermis, and excrete directly onto the surface of the skin. [8] [5] [26] [4] The proportion of eccrine glands decreases with age ...
Sweating is controlled by the sympathetic nervous system, [4] and skin conductance is an indication of psychological or physiological arousal. If the sympathetic branch of the autonomic nervous system is highly aroused, then sweat gland activity also increases, which in turn increases skin conductance.
Merocrine is the most common manner of secretion. The gland releases its product and no part of the gland is lost or damaged (compare holocrine and apocrine). The term eccrine is specifically used to designate merocrine secretions from sweat glands (eccrine sweat glands), [1] although the term merocrine is often used interchangeably. [2] [3]
Neuroendocrinology arose from the recognition that the brain, especially the hypothalamus, controls secretion of pituitary gland hormones, and has subsequently expanded to investigate numerous interconnections of the endocrine and nervous systems. The endocrine system consists of numerous glands throughout the body that produce and secrete ...
