- Definition
- Any of the intralobular secretory duct of the parotid gland which connects an intercalated duct to an interlobular excretory duct; striated ducts are lined by cuboidal to columnar acidophilic cells and are so-named because of characteristic striations in the basal portions of the cells which are due to the alignment of mitochondria between deep infoldings of the basal cell membrane; the nucleus is in the central part of the cell above the striations; as they approach the excretory ducts, their diameter may exceed that of the acini; striated ducts reabsorb sodium and secrete potassium.
