353. The Stomach and the Duodenum, 



after removal of the anterior wall. 



Between the cardiac and pyloric orifices the outline of the 

 stomach is curved along its upper and lower borders; the upper con- 

 cave border forms the lesser curvature, Curvatura minor, and the 

 lower convex, the greater curvature, Curvatura major. The two sur- 

 faces of the organ, the anterior, and the posterior, are limited by these 

 two curvatures. If the stomach is filled, the anterior surface becomes 

 an upper, and the posterior surface a lower. The peritoneal covering of 

 the stomach is continued from it to the neighbouring organs by means of 

 duplic'atures ; where the membrane passes from the cardia to the diaphragm, 

 it forms the gastro-phrenic ligament, Ligamentum-phrenico-gastricum ; 

 where it passes from the fundus of the stomach to the spleen, it forms 

 the gastro-splenic ligament, Ligamentum gastro-licnale ; from the 

 lesser curvature of the stomach to the transverse fissure of the liver it 

 forms the lesser omentum, Ligamentum hepato-gastricum, s. Omentum minus. 

 The great omentum, Ligamentum gastro-colicum ft. Omentum majus, passes 

 down from the greater curvature of the stomach, covering the small intestines ; 

 it is a duplicature of the peritoneum, which then ascends to the trans- 

 verse colon, and thence extends back to the pancreas (see Fig. 368 

 and 369). The layers of the stomach from without inwards are: the 

 peritoneum (serous coat), the muscular coat (longitudinal, circular and 

 oblique fibres), and the mucous membrane rich in glands.
