Striated duct

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. 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.

Striated ducts are part of the intralobular ducts.

They are found in the submandibular gland, sublingual duct, and the parotid gland, but are more developed in the parotid gland.

They are not present in pancreas.
