7^<> A MANUAL OF ANATOMY 



The ligament of the stomach is called the gastro-phrenic liga- 

 ment. It is of small size, and extends between the region of the 

 uncovered trigone of the stomach and the inferior surface of the 

 diaphragm, lying immediately to the left of the lower end of the 

 oesophagus. 



The ligaments of the spleen are two in number, namely, phreno- 

 splenic or lieno-phrenic, and lieno-renal. 



The phreno-splenic or lieno-phrenic ligament is also called the 

 suspensory ligament. It extends between the spleen, near its upper 

 extremity, and the contiguous part of the diaphragm. The lieno- 

 renal ligament extends from the hilum of the spleen to the front 

 of the left kidney at its upper and outer part. Its direction is 

 backwards, and it is composed of two layers of peritoneum, right 

 and left, which contain between them the splenic branches of the * 

 splenic artery. The right layer coiresponds with the posterior 

 layer of the gastro-splenic omentum, and the left with the anterior 

 layer of that omentum. 



The phreno-colic or costo-colic ligament {sustentaculum lienis) 

 extends between the splenic flexure of the colon and the diaphragm 

 opposite the tenth or eleventh left rib. It is triangular, and its 

 surfaces are superior and inferior, its anterior border being free. It 

 forms a platform upon which the basal surface of the spleen rests. 



The sustentaculum hepatis is a fold of peritoneum which is sometimes met 

 with in connection with the ascending colon. (Treves found it in eighteen 

 out of one hundred bodies.) When present it extends from the right side 

 of the ascending colon to the abdominal wall at a point a little above the 

 level of the iliac crest. Its free border looks forwards, and it forms a shelf 

 which supports the right margin of the liver. 



Cavity of the Peritoneum. — The peritoneal cavity is divided into 

 two compartments, great and small, which communicate with each 

 other through the foramen of Winslow behind the right or free 

 border of the gastro-hepatic omentum. 



The great cavity or sac is the space which is exposed to view after 

 opening the abdominal cavity. It is separated from the small sac 

 by the liver, gastro-hepatic omentum, stomach, gastro-colic omen- 

 tum, gastro-splenic omentum, lieno-renal ligament, and transverse 

 meso-colon. 



The small cavity or sac is an offshoot from the great sac, the 

 introversion taking place at the foramen of Winslow. It extends 

 upwards behind the stomach to the posterior part of the inferior 

 surface of the diaphragm and the Spigelian lobe of the liver, and 

 downwards into the gastro-colic omentum, the part of it within 

 that omentum being known as the bag or sac of the great omentum. 



Boundaries of the Small Sac — Anterior. — From below u]nvards, 

 the two anterior or descending layers of the gastro-colic omentum, 

 the posterior surface of the stomach, the gastro-hepatic omentum, 

 and the posterior surface of the Spigelian lobe of the liver. Posterior. 

 — From below upwards, the two posterior or ascending layers of the 

 gastro-colic omentum, the transverse colon, the transverse meso- 

 colon, and the asceftding layer of the transverse mcso-colon.
