Homo sapiens celiac ganglion http://upload.wikimedia.org/wikipedia/commons/6/63/Gray848.png MA:0001158 BTO:0006296 coeliac ganglion The celiac 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). The ganglion on the right side is placed behind the inferior vena cava. They are sometimes referred to as the semilunar ganglia or the solar ganglia. [WP,unvetted].
