词条 | Striated duct |
释义 |
A striated duct (Pflüger's ducts ) 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, making the saliva hypotonic. 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] sublingual duct, and the parotid gland, but are more developed in the parotid gland.[6] They are not present in pancreas.
