Ultrastructure of the intrahepatic bile duct system of the one-humped camel (Camelus dromedarius)

The ultrastructure of the intrahepatic bile duct system of the camel was studied. Bile canaliculi are present as cavities containing numerous microvilli between adjacent hepatic cells. They are lined with cuboidal cells surrounded by a basal lamina. The lateral plasma membranes of adjacent cells form extensive evaginations below tight junctions at the lumenal surface. The basal surface is open. Collagen bundles are arranged mainly in parallel to the duct.
