Nerves of the female pelvis (English)

The lumbar, sacral and coccygeal plexus give off several pelvic branches such as the obturator nerve, pudendal nerve and anococcygeal nerves. These nerves provide motor and sensory innervation to the muscles of the pelvic floor and perineum. Lumbar and sacral splanchnic nerves provide the pelvis with autonomic innervation via the superior hypogastric plexus. This plexus gives off the left and right hypogastric nerves that merge with the pelvic splanchnic nerves to form the inferior hypogastric plexus. The superior and inferior hypogastric plexus further divide into smaller plexuses, forming the vesical plexus, uterovaginal plexus and [ano]rectal plexuses. These subplexuses provide autonomic innervation to the female pelvic viscera, glands and blood vessels, including the rectum, urinary bladder, urethra, uterus, ovaries and vagina.
