THE EXTERNAL ILIAC ARTERY. 251 



tures. (c) Transverse perineal, to the muscles ; lies on 

 transversus perinei. (d) Artery of the bulb, short and 

 thick ; runs to the bulb, (e) Artery of the corpus cav- 

 ernosum ; pierces the eras penis and is distributed to it. 

 (/) Dorsal artery of the penis; supplies prepuce and glans. 



7. Sciatic. The other terminal branch of the an- 

 terior trunk passes out of pelvis with the internal pudic. 

 It sends off muscular branches, articular branches, and 

 a branch to the sciatic nerve. 



In the Female, in Addition. 



8. Uterine. Ascends at the side of the uterus be- 

 tween the layers of the broad ligament and is distributed 

 to the uterus. 



9. Vaginal. Supplies the lower part of the vagina. 



The Posterior Trunk. 



The posterior trunk sends off: 



Ilio-himbar. Is a recurrent branch that supplies 

 the muscles in the iliac fossa and the lumbar region. 



Lateral Sacral. Two or three branches which enter 

 the anterior sacral foramina and anastomose with the 

 sacra media and the arteries of the spinal canal. 



Gluteal. Passes out of the pelvis above the pyri- 

 formis and divides into a deep and superficial branch, 

 which supplies the skin and the gluteal muscles. This 

 vessel forms free anastomoses among its branches. 



THE EXTERNAL ILIAC ARTERY. 



The external iliac artery is the continuation of the 

 common iliac, which passes beneath Poupart's ligament, 

 and is continued down the thigh as the femoral artery. 

 Just before it passes out of the pelvis, beneath Poupart's
