VISCERAL ANATOMY. 



What are the Omenta or Epiploa ? They are folds of peritoneum con. 

 necting the stomach with other organs, and are 3 in number, namely, the 

 Gastro-colic or Great Omentum,^* consists of four layers of peritoneum, 



the most anterior and posterior of which 

 belong to the greater sac, the two inter- 

 nal to the lesser sac. The two anterior 

 layers descend from the stomach and the 

 spleen, over the small intestines, and 

 then ascend as the posterior layers, to 

 enclose the transverse colon. 

 Gastro- hepatic or Lesser Omentum, con- 

 sists of two layers of peritoneum, the 

 upper belonging to the greater sac, the 

 lower to the lesser sac. It extends from 

 the transverse fissure of the liver to the 

 lesser curvature of the stomach, and con- 

 tains in its right free margin the 

 Hepatic Artery. 

 Portal Vein. 

 Lymphatics. 



Ductus Communis Choledochus. 

 First part of the Duodenum. 

 Hepatic Plexus of Nerves. 

 Gastro- splenic Omentum, connects the 

 stomach with the spleen, and is con- 

 tinuous by its lower border with the 

 great omentum. It contains the Splenic 

 Vessels and the Vasa Brevia. 

 What are the Mesos or Mesenteries ? Folds of peritoneum connect- 

 ing the various parts of the intestinal canal (except the duodenum) to the 

 abdominal walls. Each one contains the vessels of the part which it sup- 

 ports. They are the 



Mesentery proper - . 19 Meso-cacum. Mesa-colon. 1 ** Meso-rectum. 

 What Ligaments are formed by the Peritoneum ? They are 17 folds 

 of peritoneum which support certain organs, viz. 



i G astro-phrenic, from the stomach to the diaphragm. 



4 Hepatic the longitudinal, coronary, and 2 lateral ligaments of the liver. 



5 Vesical, the false ligaments of the bladder. 



6 Uterine, 2 vesico-uterine, 2 recto-uterine, and 2 lateral or broad liga- 

 ments of the uterus. 



I Splenic., the suspensory ligament of the spleen.
