ANATOMY OF THE RABBIT. 
The pyloric limb (pars pylorica) forms the right portion 
of the organ. 
The pylorus, the point of communication of the stomach 
with the intestine (duodenum). It is marked by an annular 
constriction, preceding which is a greatly thickened muscular 
portion of the pyloric limb, known as the pyloric antrum 
(antrum pyloricum). 
2. Raise the posterior portion of the stomach and turn it for- 
ward. 
Note on the dorsal surface of the greater curvature a dark 
red elongated body, the spleen (lien). On the right side of its 
artery, enclosed in the peritoneum, will be seen a diffuse brownish 
glandular mass, a portion of the pancreas. Trace the course of the 
peritoneum from the dorsal abdominal wall to the liver, as follows: 
(a) A broad fold of peritoneum, the mesogastrium, connects 
(b) 
(c) 
the dorsal abdominal wall and the diaphragm with the left 
side and dorsal surface of the greater curvature. Its 
posterior portion is divided into two parts by the spleen 
The dorsal part, the phrenicosplenic ligament (lig. phreni- 
colienale) connects the spleen with the dorsal body-wall. 
The ventral part, the gastrosplenic ligament (lig. gastro- 
ienale) connects the spleen with the greater curvature 
(cf. Fig. 40). 
The peritoneum is projected backward from the greater 
curvature as a free fold, the greater omentum (omentum 
majus), which covers the intestines to a,certain extent. It 
usually contains fat. It is composed of four leaves, of which 
two come from the surface of the stomach and two others 
pass forward in a dorsal position from the free posterior 
border to unite with the transverse mesocolon. ; 
The lesser omentum (omentum minus) passes from the 
lesser curvature and the duodenum to the posterior surface 
of the liver. Its thickened margin on the right side forms 
the hepatoduodenal ligament (lig. hepatoduodenale) 
which carries three important structures, namely, the 
common bile duct, the hepatic artery and the portal vein. 
Its left portion forms a thin membrane, the hepatogastric 
omentum, connecting the caudate lobe with the lesser 
curvature.
