block10-1_17.jpg - Fig 7. 93W4508 Stomach, composite (sec.) H&E.Three regions of the stomach are shown in this slide: upper,pylorus; middle, fundus; lower, cardia (as shown in Fig 7a).As with other parts of the gastrointestinal tract, the wall of thestomach consists of four layers: a mucosa, a submucosa, amuscularis externa, and a serosa. The inner surface of theempty stomach is thrown into long folds referred to as rugae (*).Several such cross-sectioned folds are shown in Fig 7a. Theyconsist of mucosa and submucosa. The rugae are notpermanent folds; they disappear when the stomach wall isstretched, as in the distended stomach.
