Renal artery kidneys leading to reduced kidney function and, possibly, renal failure. Renal artery The renal arteries normally arise off the left interior side of the abdominal aorta, immediately below the superior mesenteric artery, and supply the kidneys with blood. Each is directed across the crus of the diaphragm, so as to form nearly a right angle. The renal arteries carry a large portion of total blood flow to the kidneys. Up to a third of total cardiac output can pass through the renal arteries to be filtered by the kidneys. It has a radius of approximately 0.25 cm, 0.26 cm at
Posterior inferior cerebellar artery medial branch continues backward to the notch between the two hemispheres of the cerebellum; while the lateral supplies the under surface of the cerebellum, as far as its lateral border, where it anastomoses with the anterior inferior cerebellar and the superior cerebellar branches of the basilar artery. Branches from this artery supply the choroid plexus of the fourth ventricle. A disrupted blood supply to this artery due to a blood clot or embolus will result in tissue damage and lead to lateral medullary syndrome, also known as posterior inferior cerebellar artery syndrome ("PICA syndrome"), or "Wallenberg syndrome."
