Ovarian artery 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. The ovarian arteries are paired structures that arise from the abdominal aorta, usually at the level of L2. After emerging from the aorta, the artery travels down the suspensory ligament of the ovary, enters the mesovarium, and may anastamose with the uterine artery in the broad ligament. The ovarian arteries are the corresponding arteries in
Posterior spinal artery anastomosis around the posterior roots of the spinal nerves, and communicate, by means of very tortuous transverse branches, with the vessels of the opposite side. Close to its origin each posterior spinal artery gives off an ascending branch, which ends ipsilaterally near the fourth ventricle. The posterior spinal artery can often originate from the posterior inferior cerebellar artery, rather than the vertebral. Most cranially, the posterior spinal artery supplies the dorsal column of the closed medulla containing fasiculus gracilis, gracile nucleus, fasciculus cuneatus, and cuneate nucleus. At the spinal cord level, the posterior spinal artery supplies the dorsal and lateral
