Sweat glands, also known as sudoriferous 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. There are two main types of sweat glands that differ in their structure, function, secretory product, mechanism of excretion, anatomic distribution, and distribution across species: eccrine and apocrine sweat glands
The luminal cells of the duct contains desmosomes for secretion The secretory cells/coil can be divided into: -a coiled segment -a long and straight segment that extends up to the epidermis -an intraepidermal segment, which joins up with a cork-screw shaped cleft between epithelial cells, opening via a circular aperture Myoepithelial cells (sometimes referred to as myoepithelium) are cells usually found in glandular epithelium as a thin layer above the basement membrane but generally beneath the luminal cells. These may be positive for alpha smooth muscle actin and can contract and expel the secretions of exocrine glands In simple tubular glands, the secretory portion is a tubular structure. Secretions are led from the secretory tubules to the point of discharge by an unbranched duct. The secretory tubules may be straight (crypts of Lieberkühn), coiled (sweat glands) or branched like those of the gastric glands, the glands of the endometrium and Brunner’s glands of the duodenum.
