Preferred Label : inferior mesenteric artery;
Uberon definition : Mesenteric artery that supplies the large intestine from the left colic (or splenic)
flexure to the upper part of the rectum, which includes the descending colon, the
sigmoid colon, and part of the rectum. Proximally, its territory of distribution overlaps
(forms a watershed) with the middle colic artery, and therefore the superior mesenteric
artery. The SMA and IMA anastomose via the marginal artery (artery of Drummond). The
territory of distribution of the IMA is more or less equivalent to the embryonic hindgut.
