Attempt to identify the following autonomic nerve plexi: celiac plexus, superior mesenteric plexus, inferior mesenteric plexus, renal plexus, suprarenal plexus and gonadal plexus (testicular plexus or ovarian plexus).

Inferior to the bifurcation of the aorta, the paraaortic plexus continues into the pelvis as the hypogastric plexus. Identify the right hypogastric nerve and left hypogastric nerve that pass into the pelvic cavity. They join the lumbar (sympathetic), sacral (sympathetic), and pelvic (parasympathetic) splanchnic nerves to provide autonomic innervation to the pelvic viscera. See a textbook for more information on the innervation of the abdominal and pelvic viscera.
