inferior mesenteric node

inferior mesenteric node

a node in one of the three groups of visceral lymph glands serving the viscera of the abdomen and the pelvis. The inferior mesenteric nodes are associated with the branches of the inferior mesenteric artery. The inferior mesenteric nodes drain the descending colon, the iliac and sigmoid parts of the colon, and the upper part of the rectum. Their efferent vessels pass to the preaortic nodes. Compare gastric node, superior mesenteric node.
