Inferior hypogastric plexus
The inferior hypogastric plexus (Latin for "lower abdominal plexus "), known in veterinary anatomy as plexus pelvinus (Latin for "pelvic plexus "), is a network of vegetative nerve fibers that supply the bowels of the pelvis . The plexus contains both sympathetic and parasympathetic fibers and communicates with the aortic abdominal plexus and the superior hypogastric plexus . From the latter, the sympathetic fibers arrive on both sides via the hypogastric nerveto the inferior hypogastric plexus. Switching to the second neuron of the sympathetic fibers takes place not only in the inferior hypogastric plexus, but also partially in the inferior mesenteric ganglion . The parasympathetic nerve fibers originate from the second to fourth sacral nerves and reach the inferior hypogastric plexus via the pelvic splanchnic nerves .
Nerve fibers originate from the inferior hypogastric plexus, which run with the blood vessels and form further plexuses on the pelvic viscera. In detail these are:
- the plexus rectales medii and inferiores : supply of the rectum
- the prostatic plexus : supply of the prostate
- the deferential plexus : supply of the vas deferens
- the uterovaginal plexus : supply of the uterus and vagina
- the vesical plexus : on the fundus of the urinary bladder
- the ureteric plexus : supply of the ureter
