Skin and Its Appendages
Sweat Glands

Sweat glands (glandulae sudorifera) are divided into apocrine glands, located in the axillary regions and around the anus, and merocrine glands, situated in other PARTS OF THE body.

In terms of their Structure, these are simple, unbranched tubular glands measuring 30-90 mm in length. The secretory segment contains light exocrinocytes and dark exocrinocytes. Dark exocrinocytes contain A large number of secretory granules in their Cytoplasm and produce a protein-polysaccharide secretion. Light exocrinocytes do not contain secretory granules; their cytoplasm has few Ribosomes and abundant Glycogen, with deep folds of the Plasmalemma on the basal surface. Light Cells secrete Water and salt. The excretory duct in the dermis is lined with a two-layered epithelium, while in the epidermis it forms a corkscrew-like cleft between keratinocytes.
