Secretory duct from the submandibular gland with adjacent capillaries 1 and secretory acini 2 . The Pseudostratified epithelial cells of the secretory duct show a clearly expressed striation pattern rectangular to the basis 3 .It is cause d by plasmalemma involutions and rows of mitochondria (basal striation,“ basal labyrinth”). These plasmalemma involutions relegate the nuclei of the Pseudostratified epithelial cells to the upper third of the cells. Note the basal basophilia of the gland cells .
