Twenty-two stillborn infants were dissected to investigate the inferior mesenteric ganglion or ganglia. Macroscopic ganglia were found in each case. In a 3d of the specimens a single ganglion lay anterior to the inferior mesenteric artery, in a further 3d along its left border, and in 4 along its right border. In the remaining 3 dissections, 2 ganglia were present. The ganglia were oval or stellate in shape and varied in size between 0.5 and 2 mm. The connections of the ganglia are described. The presence of ganglionic neurons was confirmed by microscopic examination.
