The celiac ganglia or coeliac ganglia are two large irregularly shaped masses of nerve tissue in the upper abdomen. Part of the sympathetic subdivision of the autonomic nervous system (ANS) the two celiac ganglia are the largest ganglia in the ANS and they innervate most of the digestive tract. They have the appearance of lymph glands and are placed on either side of the midline in front of the crura of the diaphragm close to the suprarenal glands (also called adrenal glands).
