Document Summary
Gross anatomy of the stomach i: functions: storage, mechanical and chemical digestion, little absorption. The greater curvature forms the lateral surface, and it is the attachment point of the greater omentum ( large apron-like fold of visceral peritoneum that hangs down from the stomach. It extends from the greater curvature of the stomach, passing in front of the small intestines and doubles back to ascend to the transverse colon before reaching to the posterior abdominal wall). Stomach has four regions: cardia, fundus, body and pyloric region. Has lower esophagea l sphincter, pyloric sphincter rugae and three layers of smooth muscle in muscularis externa (slide 18) Histology of stomach: four layers-mucosa: simple columnar epithelia, attached to lamina propia. Submucosa-no notes on this but has connective tissue, arteries and veins, and lymph nodules from picture. Muscularis externa: has oblique, circular and longitudinal muscle. Histology of stomach ii: all of these cells are in the mucosal later.
