Gastric folds

The gastric fold, or fold of the stomach (lat. plicae gastricae) is the general name for small ring-shaped outgrowths in the wall of the stomach that do not penetrate under its mucous membrane. In other words, this is a thickening of part of the stomach wall, but without breaking through the epithelial layer. Gastric folds are present in all animals and humans. They are the physiological norm of the anatomy of the stomach. But they can act as a pathological deviation.
