These fibers anastomose with sudomotor sympathetic fibers of the skin, thereby gaining control of sweat gland activity. Apocrine sweat glands are larger than eccrine glands, with a 10-fold greater diameter 8). Apocrine sweat is more viscous and produced in much smaller amounts than eccrine sweat (which actually is the wet portion of axillary sweat). 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. A histomorphological and histochemical study was made on the nerve supply to the apocrine sweat glands in the general hairy skin of the goat. 1.

The apocrine gland secretes an oily fluid with proteins, lipids, and steroids that is odorless before microbial activity. activity of the enzyme known to catalyze this phospho-rylation, the AMP-activated protein kinase, was also measured. 74. The exact function of apocrine glands is unclear, although they are thought to represent scent glands.

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. 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 … Define apocrine glands.
