Striated duct

From Wikipedia, the free encyclopedia

A striated duct is a gland duct which connects an intercalated duct to an interlobular duct. It is characterized by the basal infoldings of its plasma membrane, characteristic of ion-pumping activity by the numerous mitochondria.[1][2] Along with the intercalated ducts, they function to modify salivary fluid by secreting HCO3− and K+ and reabsorbing Na+ and Cl− using the Na-K pump and the Cl-HCO3 pump.

Their epithelium can be simple cuboidal or simple columnar.[3]

Striated ducts are part of the intralobular ducts.

They are found in the submandibular gland[4][5] and the parotid gland.[6]

They are not present in pancreas.
