Chief cells can be identified by their large secretion granules near their apical surface. The chief cell at the bottom is seen in cross-section, while parts of four more chief cells are seem across the top of the section.
Parietal cells can be identified by (1) canalculi or the tubulovesicular system (e.g., tubules and cisternae) and (2) the large number of mitochondria. The presence of canalculi or the tubulovesicular system indicates whether the cell is actively secreting hydrochloric acid (HCl) or are "resting" cells, respectively.
Cross-sections through the edges of parietal cells is seen on the left and right sides. These are "resting" cells not actively secreting HCl.
