Stomach. 



352. The Stomach and the Duodenum, view from before. 



The oesophagus' or gullet extends from the pharynx to the 

 stomach. In the neck it lies behind and a little to the left of the trachea ; 

 it descends in the posterior mediastinum, opposite the place of bifurcation 

 of the trachea, along the right side of the aorta, crosses the artery 

 further down and passes through the oesophageal opening of the diaphragm 

 to the stomach. 



The stomach, Vcntrlculus s. stomacJnis, lies in the epigastric region; 

 above it is the diaphragm, below the transverse colon, behind 

 the pancreas, and to the left side the spleen. It presents a cardiac 

 orifice, Cardia (Ostium ocsoplicKjcum') a pyloric orifice, Pylorus (Ostium 

 dnodenale), and an expanded part, the great cul-de-sac or fundus, 

 Funclus ventriculi. This is the largest part of the stomach, and from there 

 it gradually narrows towards the pylorus, in front of which is a prominence 

 or bulging, called the small cul-de-sac or Antrum pyloricum Willisii. At 

 the pylorus, between the stomach and duodenum is a distinctly visible, 

 slight constriction.
