SPLANCHNOLOGY 





In most cases the peritoneum covers only the front and sides of the ascending 

 and descending parts of the colon. Sometimes, however, these are surrounded 

 by the serous membrane and attached to the posterior abdominal wall by an 

 ascending and a descending mesocolon respectively. A fold of peritoneum, the 

 phrenicocolic ligament, is continued from the left colic flexure to the diaphragm 

 opposite the tenth and eleventh ribs; it passes below and serves to support the 

 spleen, and therefore has received the name of sustentaculum lienis.

to invest the viscera. 



The appendices epiploicee are small pouches of the peritoneum filled with fat 

 and situated along the colon and upper part of the rectum. They are chiefly 

 appended to the transverse and sigmoid parts of the .colon. 



Peritoneal Recesses or Fossae (retroperitoneal fossa?) . In certain parts of the 

 abdominal cavity there are recesses of peritoneum forming culs-de-sac or pouches, 

 which are of surgical interest in connection with the possibility of the occurrence 

 of "retroperitoneal" hernise. The largest of these is the omental bursa (already 

 described), but several others, of smaller size, require mention, and may be divided 

 into three groups, viz. : duodenal, cecal, and intersigmoid.
