Document Summary

* once the internal iliac dips down into the pelvis, it gives off a posterior and anterior division and all of the visceral branches will come from the anterior division. One of the visceral branches is the superior vesical artery (one from each side) and it is present in both sexes and supplies the bladder. There is an inferior vesical artery that supplies lower down the prostate and all of the other components of the male reproductive tract that are associated with the posteroinferior aspect of the bladder. Also, the uterine artery crosses the ureter and has a key relationship to the ureter in the females. * note: all of the structures are midline unpaired structures that have been formed by the fusion of two halves and so the vessels supplying them are paired one from each side. * the superior rectal artery is the direct continuation of the inferior mesenteric artery.
