Where does the internal iliac artery come from?
The internal iliac artery arises at the bifurcation of the common iliac artery, opposite the lumbosacral articulation, and, passing downward to the upper margin of the greater sciatic foramen, divides into two large trunks, an anterior and a posterior.
Where is the ovarian artery?
The ovarian artery is an artery that supplies oxygenated blood to the ovary in females. It arises from the abdominal aorta below the renal artery. It can be found in the suspensory ligament of the ovary, anterior to the ovarian vein and ureter.
What artery supplies the prostate?
Blood Supply and Lymphatics The inferior vesical artery is the major blood supply for the prostate, and it also receives blood supply from the middle rectal and internal pudendal arteries. Veins around the prostate form the prostatic plexus which drains into internal iliac veins.
What is the superior vesical artery?
