Uterovaginal plexus

from Wikipedia, the free encyclopedia

The uterovaginal plexus (Latin for "utero-vaginal plexus", syn. Uterovaginale ganglion , Frankenhäuser ganglion ) is a nerve plexus ( plexus ) of the autonomic nervous system for the innervation of the uterus and vagina .

The sympathetic nerve fibers originate in the lumbar and cross sections of the spinal cord and pass through the hypogastric nerves , the prevertebral ganglia in the sacrum and the inferior hypogastric plexus to the uterovaginal plexus. The nerve fibers are mostly preganglionic and are only switched to the second neuron in the uterovaginal plexus . The parasympathetic nerve fibers originate from the second to fourth cross nerves and reach the uterine-vaginal plexus via the pelvic splanchnic nerves . The plexus also contains sensory nerve fibers ( viscera afferents ) that run with the sympathetic parts to the 12th thoracic to the 3rd lumbar segment of the spinal cord and with the sacral plexus to the cross section of the spinal cord.
