Abstract

Splanchnic nerves are bilateral visceral autonomic nerves. The thoracic, lumbar and sacral splanchnic nerves are sympathetic in function while the pelvic splanchnic nerves are parasympathetic. These nerves have connections to the celiac, aortic, mesenteric, hypogastric and pelvic plexuses. They control the functions of the gut and pelvic organs. Splanchnicectomies are sometime performed to alleviate intractable abdominal and pelvic pains.
