Venules from this plexus pass between medullary chromaffin cells to medullary veins, which they enter between prominent bundles of smooth muscle fibres. Some relatively large arteries bypass this indirect route and pass directly to the medulla (Fig. 72.4). At operation the arteries are rarely obvious, but the veins deserve specific attention (see below). Superior suprarenal arteries The superior suprarenal artery arises from the inferior phrenic artery, a branch of the abdominal aorta: it is often small and may be absent. Middle suprarenal arteries The middle suprarenal artery arises from the lateral aspect of the abdominal aorta at the level of the superior mesenteric artery, It ascends slightly and runs over the crura of the diaphragm to the suprarenal glands, where it anastomoses with the suprarenal branches of the infe- FUNNY STUFF ON MEMEPIX.COM MEMEPIX.COM This kiwi looks like a kidney.omg-humor.tumblr.com
