Celiac Ganglion

The celiac ganglion is a cluster of neurons of the sympathetic nervous system, located on the anterior surface of the abdominal aorta, at the base of the celiac arterial trunk. It innervates the stomach, pancreas, liver, and part of the small intestine. The celiac ganglion is part of the collateral ganglia. Its sympathetic fibers anastomoses with the sympathetic plexus of the abdomen. The block of the celiac ganglion is performed to relieve chronic abdominal pain.
