| The superior hypogastric plexus lies on the abdominal aorta below the inferior mesenteric artery, and passes over the common iliac arteries to enter the pelvis. It is continuous above with the intermesenteric plexus, and it receives the lower lumbar splanchnic nerves (L3 and L4). It contains preganglionic and postganglionic sympathetic fibers, but no parasympathetics. After passing over the common iliac arteries and into the pelvis, the superior hypogastric plexus aggregates into two bundles, the right and left hypogastric nerves, that continue inferiorly to form the inferior hypogastric plexus. |  |
