The nerves that branch from the inferior mesenteric ganglion (IMG) are a major source of sympathetic nerves, which dominate the immune response of the female reproductive system.
Inferior mesenteric ganglion (IMG) is prevertebral ganglia, hypogastric nerve which is gave off by IMG is major source of sympathetic nerve that dominate uterus (Schofield, 1952; Owman, 1981).
The exciting origin of guinea-pig inferior mesenteric ganglion neurons in vivo.
Our previous studies revealed that the coeliac-superior mesenteric ganglion (CSMG) complex is the main source of sympathetic innervation of the porcine stomach .
Following perfusion, the coeliac-superior mesenteric ganglion (CSMG) complexes were collected and post-fixed by immersion in the same fixative for 20 minutes, rinsed in phosphate buffer (pH 7.4) for three days, and then stored in a 30% buffered sucrose solution until sectioning.

The PVG consists of the celiac ganglion (CG, an intimately connected pair), a single superior mesenteric ganglion (SMG), a single inferior mesenteric ganglion, a pair of splanchnic ganglia in the large splanchnic nerves, and an inter-renal ganglion located in the intermesenteric nerve between the SMG and inferior mesenteric ganglion.
In the present study, we performed the following procedures to determine which [beta]-adrenoceptors are involved in delayed GE induced by the phenylpyrazole derivatives dipyrone, 4-aminoantipyrine, and antipyrine, and to identify participation of the prevertebral SNS in this process in rats: i) blockade of [beta]-adrenoceptors with the selective antagonists atenolol, butoxamine, and SR59230A, and ii) concomitant surgical resection of the celiac ganglion and the superior mesenteric ganglion.
Typically, one will find paraspinal muscle involvement, especially in the thoracolumbar junction from T10-L2, which feeds the thoracic and lumbar paraspinal musculature, the superior mesenteric ganglion, and the ileocecal valve itself.
Differential diagnosis needs to include IBS, inflammatory bowel disease, Crohn's disease, appendicitis, ulcerative colitis, vagal innervation-type dysfunction, superior mesenteric ganglion compression or inflammation, and vascular problems of the mesenteric arteries and/or venous supply.
