Hypogastric nerve

from Wikipedia, the free encyclopedia

The nervus hypogastricus ( Latin nervus and hypogasticus , Latinized from ancient Greek ὑπό hypó , German 'under' and ancient Greek γαστήρ gastḗr , German 'belly' : 'lower abdominal nerve ') is a nerve of the vegetative nervous system , especially the sympathetic nerve . The hypogastric nerve arises in humans on both sides from the superior hypogastric plexus , in most other mammals directly from the caudal mesenteric ganglion and runs into the pelvic cavity on the left and right , where it, together with the parasympathetic fibers of the pelvinus nerve and other sympathetic fibers Forms the inferior hypogastric plexus .

The hypogastric nerve is responsible for the sympathetic innervation of the pelvic viscera. The sympathetic nervous system ensures urinary incontinence by preventing the urinary bladder from emptying . It also lowers the peristalsis of the rectum . In male mammals, it is responsible for ejaculation .
