Translations:Magen (Gaster)/65/en

The stomach lies within the peritoneum (intraperitoneal) and is located in the immediate vicinity of various organs. The curved organ contours on both sides of the stomach are called large (curvaturagastrica major) and small (curvaturagastrica minor) stomach curvatures. Ventrally, the left lobe of the liver towers above the stomach up to the left upper abdomen. The stomach is dorsally adjacent to the spleen. The stomach has two mesogastria as developmental rudiments, which develop further as omentum majus and minus as well as connecting lines between stomach and adjacent organs and include the net bag (bursa omentalis). The bursa omentalis is the slit-shaped displacement space of the peritoneal cavity, which lies dorsally from the stomach. The back wall of the bursa omentalis is formed by the pancreas. For gastric peristalsis, the peritoneal coating plays an important role, as it establishes mobility in relation to the neighbouring organs.
