MYOEPITHELIAL CELLS: STRUCTURE, FUNCTION & IDENTIFICATION
Author: Sanketh DS, MDS
The secretory cells present in salivary glands are of two types, called serous and mucous cells. These secretory cells, also called acinar cells are housed in secretory end pieces. The secretory end pieces are continuous with the main excretory duct of the salivary gland through intermediary ducts. The lumen of the end pieces open into the intercalated duct, which is continuous with the striated duct, which in turn opens into the excretory duct of the salivary gland. Also note that the ducts are lined by ductal cells. Now, the secretory end pieces and intercalated ducts are associated with stellate shaped contractile cells called the myoepithelial cells.
