How are apocrine and eccrine sweat glands different?
Eccrine sweat glands are smaller sweat glands. They are coiled tubular glands that discharge their secretions directly onto the surface of the skin. Apocrine sweat glands are coiled tubular glands that discharge in the canals of hair follicles.
How do eccrine and apocrine sweat glands differ in structure and function?
Apocrine sweat glands are associated with hair follicles; eccrine sweat glands are not. Both types of glands secrete onto the body surface. Eccrine glands cool the body; apocrine glands function as scent glands.
What are the functions of the eccrine and apocrine sweat glands?
Eccrine glands are found all over the body and secrete a watery product that cools the skin. Apocrine sweat glands are mainly found in the armpits and perianal area, and secrete a more viscous, odorous product.
Where are eccrine sweat glands located?
Eccrine sweat glands (/ˈɛkrən, -ˌkraɪn, -ˌkriːn/; from Greek ekkrinein ‘secrete’; sometimes called merocrine glands) are the major sweat glands of the human body, found in virtually all skin, with the highest density in palm and soles, then on the head, but much less on the torso and the extremities.
What organ system controls the activity of the eccrine sweat glands?
The eccrine sweat gland, which is controlled by the sympathetic nervous system, regulates body temperature. When internal temperature rises, the eccrine glands secrete water to the skin surface, where heat is removed by evaporation.
Where are eccrine sweat glands?
Eccrine sweat glands are simple, coiled, tubular glands present throughout the body, most numerously on the soles of the feet. Thin skin covers most of the body and contains sweat glands, in addition to hair follicles, hair arrector muscles, and sebaceous glands.
Where do you find apocrine glands?
Most apocrine glands in the skin are in the armpits, the groin, and the area around the nipples of the breast. Apocrine glands in the skin are scent glands, and their secretions usually have an odor. Another type of gland (eccrine gland or simple sweat gland) produces most sweat.
What are 3 types of sweat glands?
There are three major types of sweat glands: eccrine, apocrine, and apoeccrine. Eccrine sweat glands are the most numerous of all glands and can be found throughout the body surface except for the lips and the glans penis. Eccrine sweat glands consist of a ductal portion and a secretory portion.
What are sweat glands?
Anatomical terminology. Sweat glands, also known as sudoriferous or sudoriparous glands, from Latin sudor, meaning ‘sweat’, are small tubular structures of the skin that produce sweat. Sweat glands are a type of exocrine gland, which are glands that produce and secrete substances onto an epithelial surface by way of a duct.
What is sweat gland carcinoma?
Sweat gland carcinoma represent a rare group of tumors with potential for destructive local tissue infiltration and regional as well as distant metastasis. The management of these neoplasms is both complex and cumbersome, mainly due to limited availability of literature.
