| superior mesenteric lymph nodes | The numerous nodes located in the mesentery along the superior mesenteric artery; they receive lymph from the central mesenteric lymph nodes and drain into the intestinal lymph trunk. Synonym: nodi lymphatici mesenterici superiores, nodi lymphatici centrales. (05 Mar 2000) |

| superior mesenteric plexus | An autonomic plexus, a continuation of the abdominal aortic plexus, sending nerves to the intestines and forming with the vagus the subserous, myenteric, and submucous plexus's; this periarterial plexus is so dense that it results in the appearance of a characteristic perivascular "collar" distinguishing the superior mesenteric artery from the superior mesenteric vein in several imaging modalities such as with ultra sound. Synonym: plexus mesentericus superior. (05 Mar 2000) |
| superior mesenteric vein | <anatomy, vein> Begins at the ileum in the right iliac fossa, ascends in the root of the mesentery, and unites behind the pancreas with the splenic vein to form the hepatic portal vein. Synonym: vena mesenterica superior. (05 Mar 2000) |
| inferior mesenteric artery | <anatomy, artery> Origin, abdominal aorta; branches, left colic, sigmoid, superior rectal; anastomoses, middle colic and middle rectal. Synonym: arteria mesenterica inferior. (05 Mar 2000) |
| inferior mesenteric ganglion | The lowest of the sympathetic prevertebral ganglia, located at the origin of the inferior mesenteric artery from the aorta and containing the sympathetic neurons innervating the descending and sigmoid colon. Synonym: ganglion mesentericum inferius. (05 Mar 2000) |
| inferior mesenteric lymph nodes | Nodes located along the inferior mesenteric artery and its branches that drain the upper part of the rectum, the sigmoid colon, and descending colon. Synonym: nodi lymphatici mesenterici inferiores. (05 Mar 2000) |
| inferior mesenteric plexus | An autonomic plexus, derived from the abdominal aortic plexus, surrounding the inferior mesenteric artery and sending branches to the descending colon, sigmoid, and rectum. Synonym: plexus mesentericus inferior. (05 Mar 2000) |
| inferior mesenteric vein | <anatomy, vein> A continuation of the superior rectal vein at the brim of the pelvis, ascending to the left of the aorta behind the peritoneum and emptying into the splenic vein or into the superior mesenteric vein or rarely in the angle between these veins. Synonym: vena mesenterica inferior. (05 Mar 2000) |
