BRANCHES OF THE POSTERIOR DIVISION. 



The posterior terminal division gives off the ilio-lumbar and lateral sacral 

 iries, and is continued as the superior glutseal artery. 



. Arteria Ilio-lumbalis. The ilio-lumbar artery runs upwards and later- 



Y, across the upper margin of the pelvis minor, to the iliac fossa. It passes 



irior to the sacro-iliac articulation, between the lumbo-sacral trunk and the 



irator nerve, and posterior to either the lower part of the common or the 



>r part of the external iliac vessels, and the psoas and iliacus muscles. 



In the iliac fossa it divides into an iliac and a lumbar branch. The iliac branch 



iomoses with branches of the deep circumflex iliac and obturator arteries, 



s offsets to the iliacus, and supplies a large nutrient branch to the ilium. 



bar branch ascends, behind the psoas major, to the crest of the ilium. It supplies 



e ipsoas and quadratus lumber urn, and anastomoses with the lumbar and deep
