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.〔 - "Mammal, salivary glands (EM, Low)"〕〔 - "Mammal, salivary glands (LM, Medium)"〕 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.〔(SIU SOM Histology GI )〕 Striated ducts are part of the intralobular ducts. They are found in the submandibular gland,〔(Histology at umdnj.edu )〕 sublingual duct, and the parotid gland, but are more developed in the parotid gland.〔(Oral histology at usc.edu )〕 They are not present in pancreas. ==References== 〔 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Striated duct」の詳細全文を読む スポンサード リンク
