Corpus: Uterovaginal plexus

The term uterovaginal plexus refers to a vegetative nerve plexus of the small pelvis which, among other things, harbours the Frankenhäuser ganglia. It borders on the inferior hypogastric plexus.

The uterovaginal plexus has sympathetic and parasympathetic parts:

• The sympathetic nerve fibres of the plexus originate from the lumbar and sacral sections of the spinal cord. They run via the hypogastric nerves and the inferior hypogastric plexus and form the uterovaginal plexus in the ligamentum latum uteri. The nerve fibres are predominantly preganglionic and are only switched to the second neuron in the uterovaginal plexus.
• The parasympathetic nerve fibres originate from segments S2 to S4 and reach the uterovaginal plexus via the pelvic splanchnic nerves.

The uterovaginal plexus supplies the uterus and vagina.
