Next, identify the branches of the anterior division of the internal iliac artery:

  • obturator artery, accompanying by the obturator nerve. These structures cross the lateral wall of the pelvis and enter the obturator canal
  • umbilical artery, giving several branches called the superior vesical arteries to the apex of the bladder. Distally the lumen of the umbilical artery is obliterated. This portion of the umbilical artery represents the medial umbilical ligament in the adult
  • inferior vesical artery, supplying the posterolateral wall of the bladder with the seminal vesicle, ampullae of ductus deferens, and partially the prostate gland. This artery usually gives off a small artery to the ductus deferens
