Innervation of the apocrine sweat glands. 1981

V E Sokolov, and S A Shabadash, and T I Zelikina

The apocrine glands of the oral angle of the squirrel, and of the hairy skin of the body and the anal sacs of the cat possess cholinergic and adrenergic innervation. Their secretory tubules are enlaced by cholinergic nerves containing chiefly non-specific cholinesterase; the acetylcholinesterase concentration in them is very low in the squirrel and i the glands of the skin of the cat's body, and higher in the glands of the anal sac of the cat. The adrenergic nerve fibers of the apocrine glands possess a very low monoamine oxidase concentration; however, their nonmyelinated terminals, lying on the secretory cells and reaching the lumen of the secretory division, are rich in monoamine oxidase. The innervation of the apocrine and eccrine sweat glands is very similar; in the nerves of the apocrine glands, the acetylcholinesterase and monoamine oxidase concentrations are lower in comparison with the nerves of the eccrine glands; the monoamine oxidase concentration is also lower in cells of the apocrine glands. The question of the essential similarity of the innervation of both types of skin glands - skin and sebaceous - is discussed.

UI	MeSH Term	Description	Entries
D008995	Monoamine Oxidase	An enzyme that catalyzes the oxidative deamination of naturally occurring monoamines. It is a flavin-containing enzyme that is localized in mitochondrial membranes, whether in nerve terminals, the liver, or other organs. Monoamine oxidase is important in regulating the metabolic degradation of catecholamines and serotonin in neural or target tissues. Hepatic monoamine oxidase has a crucial defensive role in inactivating circulating monoamines or those, such as tyramine, that originate in the gut and are absorbed into the portal circulation.

D002395	Catecholamines	A general class of ortho-dihydroxyphenylalkylamines derived from TYROSINE.	Catecholamine,Sympathin,Sympathins
D002415	Cats	The domestic cat, Felis catus, of the carnivore family FELIDAE, comprising over 30 different breeds. The domestic cat is descended primarily from the wild cat of Africa and extreme southwestern Asia. Though probably present in towns in Palestine as long ago as 7000 years, actual domestication occurred in Egypt about 4000 years ago.

D006651	Histocytochemistry	Study of intracellular distribution of chemicals, reaction sites, enzymes, etc., by means of staining reactions, radioactive isotope uptake, selective metal distribution in electron microscopy, or other methods.	Cytochemistry
D000110	Acetylcholinesterase	An enzyme that catalyzes the hydrolysis of ACETYLCHOLINE to CHOLINE and acetate. In the CNS, this enzyme plays a role in the function of peripheral neuromuscular junctions. EC 3.1.1.7.	Acetylcholine Hydrolase,Acetylthiocholinesterase,Hydrolase, Acetylcholine
D000695	Anal Sacs	A pair of anal glands or sacs, located on either side of the ANUS, that produce and store a dark, foul-smelling fluid in carnivorous animals such as MEPHITIDAE and DOGS. The expelled fluid is used as a defensive repellent (in skunks) or a material to mark territory (in dogs).	Anal Glands, Animal,Anal Gland, Animal,Anal Sac
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D001050	Apocrine Glands	Large, branched, specialized sweat glands that empty into the upper portion of a HAIR FOLLICLE instead of directly onto the SKIN.	Apocrine Gland,Gland, Apocrine,Glands, Apocrine
D012589	Sciuridae	A family of the order Rodentia which contains 49 genera. Some of the more common genera are MARMOTA, which includes the marmot and woodchuck; Sciurus, the gray squirrel, S. carolinensis, and the fox squirrel, S. niger; Tamias, the eastern and western chipmunk; and Tamiasciurus, the red squirrel. The flying squirrels, except the scaly-tailed Anomaluridae, also belong to this family.
