Apocrine glands: Apocrine glands are usually located in areas that have hairs-underarms, external genital parts and around the anus. Another type of gland (eccrine gland or simple sweat gland) produces most sweat. The part of the gland that opens onto the skin or hair follicle is known as the acrosyringium.Whilst sweat glands share a basic structure, apocrine and eccrine sweat glands have many differences which are outlined during the rest of this article.

Earlier literature may also refer to the eccrine sweat gland as the small sweat gland and to the apocrine sweat gland as the big or scent gland. adj., adj glan´dular. Human apocrine and sebaceous glands function to secrete lipids, predominantly triglycerides, fatty acids, cholesterol and its esters, and, in the sebaceous gland, squalene. Within the basal region, they contain myoepithelial cells with contractile properties that assist in the movement of secretory products upward and outward. D. produces sweat on the palm of the hand. Morphological evidence for the innervation of apocrine sweat glands in the general hairy skin of the goat. A small amount is found in the axillae. The activity of apocrine sweat glands A. produces cerumen. 73. activity of the enzyme known to catalyze this phospho-rylation, the AMP-activated protein kinase, was also measured. the differentiation by their opening either into the hair follicle or freely onto the epi-dermal surface [38, 39]. Most apocrine glands in the skin are in the armpits, the groin, and the area around the nipples of the breast. Apocrine sweat glands receive adrenergic sympathetic innervation. Compactin was shown to inhibit HMG-CoA T he major, if not sole function of human apocrine sweat glands and sebaceous glands is lipid secretion. 1. ... First, the neoplastic clear cell proliferation was found in the dermis with normal apocrine glands. The other type, eccrine glands , is designed to secrete odorless perspiration laced with salt and electrolytes. B. leads to body odor. In fact, apocrine glands are one of two types of sweat glands found on mammals. The skin in this forehead area contains large numbers of secretory glands called apocrine sweat glands. asked Sep 26, 2016 in Anatomy & Physiology by Fernandez. The exact function of apocrine glands is unclear, although they are thought to represent scent glands. Their primary sympathetic stimulation is adrenergic. There are two types of sweat glands present in the skin layer; one kind are the apocrine sweat glands which secrete fluid into the sac of hair follicle through which it eventually comes out on the skin. Activity Description. Apocrine hidrocystoma is a rare benign cystic tumor of the apocrine sweat glands. Unlike eccrine sweat glands, which secrete continuously, the apocrine glands secrete in periodic spurts. B. serve as "anchors" for the arrector pili muscles. A histomorphological and histochemical study was made on the nerve supply to the apocrine sweat glands in the general hairy skin of the goat. Sweat glands with three morphologic types of epithelium were observed. Glands are divided into two main groups, endocrine and exocrine. Apocrine gland definition is - a gland and especially a sweat gland that secretes a viscous fluid into a hair follicle (as in the armpit or groin), is lined with a single layer of usually columnar cells, and typically does not become active until puberty. apocrine gland: [ gland ] an aggregation of cells specialized to secrete or excrete materials not related to their ordinary metabolic needs. anatomy-and-physiology 74. The activity of apocrine sweat glands. These fibers anastomose with sudomotor sympathetic fibers of the skin, thereby gaining control of sweat gland activity. Aoki T, Narita T. Cell Tissue Res, 221(1):221-226, 01 Jan 1981 Cited by: 0 articles | PMID: 7317944 Sweat gland (cross-sectional view) Sweat glands open into the skin’s surface, or in the case of apocrine sweat glands, into hair follicles. Eccrine sweat glands are found all over the body, but they occur in the highest density in the palms, soles. Define apocrine gland. Because apocrine sweat glands respond to norepinephrine, they are involved in emotional sweating due to stress, fear, pain, and sexual stimulation. Of the anti‐adrenergic substances examined (dibenamine, phenoxybenzamine, bretylium, guanethidine and phentolamine) only high doses of guanethidine and phentolamine produced any consistent and significant measure of blockade, and small doses of … Sweat glands that produce body odor. Apocrine sweat consists mainly of sialomucin. It most commonly presents as a solitary, asymptomatic, papule or nodule and is most often located on the head and neck. The other kind is the eccrine sweat gland which secretes sweat directly onto the surface of the skin. The morphology of apocrine sweat glands in two breeds of cattle, the White Fulani and Friesian was studied histologically using biopsy midside skin samples obtained from the animal at 6.00 a.m. (period 1), 2.30 p. m. (period 2) and 4.00 p. m. (period 3), respectively. Apocrine sweat glands are larger than eccrine glands, with a 10-fold greater diameter 8). D. produces sweat on the palm of the hand. LIST: 10 holiday #BeautyGoals HS is a chronic, inflammatory skin disorder that causes abscesses and scarring on the skin, affecting areas rich in apocrine glands such as the armpits, breasts and groin. The effects of blocking agents on the responsiveness of the cast' pad and human forearm sweat glands have been studied. Three major types of skin glands are recognized according to their product, the excretory function, and the location, where the excretory ducts release their products (diseases of these glands are listed in Table 6-1).Regarding their product, skin glands are classified into glands secreting sebum (sebaceous glands) and sweat (sweat glands). Apocrine sweat is more viscous and produced in much smaller amounts than eccrine sweat (which actually is the wet portion of axillary sweat). ... Any form of vigorous physical activity … However, apocrine sweat glands release a fat-infused liquid that, when pushed to … Define apocrine glands. Sweat glands that produce body odor. of sweat glands into epitrichial and atrichial was suggested, i.e. D. produces cerumen. E. produces an oily secretion. The activity of apocrine sweat glands A. produces cerumen. Apocrine glands in the skin and eyelid are sweat glands. Apocrine sweat gland tumors are rather common in dogs and tend to occur on the head, neck, and limb. The measurement of 5 alpha-reductase activity of various components of the skin obtained from 7 men and 5 women revealed that the sweat gland (probably apocrine) in the axillary skin possessed the highest activity of 5 alpha-reductase: the value was nearly 400 pmoles/mg dry weight/hr in … They occur in the armpits and genital area and become active at puberty. High levels of 5alpha-reductase activity have been detected in human apocrine glands, and the concentration of dihydrotestosterone has been found to be higher than that of testosterone in the nuclear fraction of the skin of patients who suffer from excessive or abnormal odour derived from apocrine sweat … Hair follicles and glands with ducts can also be found in this skin layer, along with sweat glands, apocrine glands, and sebaceous glands.

Apocrine lipid is associated with the generation of axillary odour E. produces an oily secretion. Under normal, resting body temperature, sweat glands produce about 500 ml/day of unnoticeable sweat sensible perspiration If body temperature rises, dilation of dermal vessels can increase sweat gland activity to produce 12 L (3 gallons) of noticeable sweat C. produce a secretion that oils the hair and skin. C. produce a secretion that oils the hair and skin. The apocrine gland secretes an oily fluid with proteins, lipids, and steroids that is odorless before microbial activity. 74. A. gives the skin a healthy glow. Occasionally, it may present in other areas. B. serve as "anchors" for the arrector pili muscles. The Activity of HMG-CoA Reductase and Acetyl-CoA Carboxylase in Human Apocrine Sweat Glands, Sebaceous Glands, and Hair Follicles Is Regulated by Phosphorylation and by Exogenous Cholesterol By Cheryl D.W. Smythe, Michael Greenall and Terence Kealey Apocrine glands are responsible for sweat production in the groin and under the armpits, whereas eccrine glands produce sweat elsewhere on the body. Apocrine sweat glands are tubular, coiled secretory glands lined by simple cuboidal epithelium that surround a larger lumen than eccrine sweat glands. Eccrine sweat glands A. aid in cooling the body.
