Layers of the Stomach. Stomach has gastric pits, which has gastric glands that secrete acids. The mucosa forms folds called rugae that look like wrinkles and flatten as your stomach gets full. Here's more about the layers of the stomach. 1. Mucosa. This is the innermost layer of the stomach.
Beneath the gastric pits, the mucosa of the stomach is filled with closely packed tubular glands, which differ by region (i.e., cardiac, fundic, pyloric). Histologically, most of the stomach wall contains gastric glands (or fundic glands).These consist primarily of parietal cells and chief cells.mages. The surface is indented into numerous short gastric pits which open freely to the lumen. The entire surface consists uniformly of surface mucous cells, which protect the stomach from self-digestion. Failure of the surface mucous cells to protect the stomach wall can lead to an ulcer.
