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] sublingual duct, and the parotid gland, but are more developed in the parotid gland.^[6]

They are not present in pancreas.

OBJECTIVE: Signalling via β-adrenergic receptors activates heterotrimeric G-proteins, which dissociate into α and βγ subunits. In salivary glands, the α subunit of Gs stimulates adenylate cyclase, increasing cyclic AMP levels and promoting exocytosis. The goals of this study were to determine G
