constricted necks of the gastric glands (5) open into the bottom of the gastric pits
(4).
The parietal cells (6, 11) are large cells with a pyramidal shape, round
nuclei, and acidophilic cytoplasm interspersed among the mucous neck cells
(10). They are the most conspicuous cells in the gastric mucosa and are found
predominantly in the upper third to upper half of the gastric glands (5). The free
surfaces of parietal cells (6, 11) open into the lumen of the gastric glands (5).
Some parietal cells (6, 11) may be binucleate (two nuclei).
Deeper in the lower half of the gastric glands (5) are the basophilic chief
(zymogenic) cells (12), which also border on the lumen of the gland. Some
parietal cells (6, 11) are also seen here.
