How do you identify an inferior mesenteric artery?
The inferior mesenteric artery arises from the left anterolateral aspect of the aorta, often just above and to the left of the umbilicus. In relation to the superior mesenteric artery, it is smaller and is situated lower, deeper, and to the left. It originates at the level of the third or fourth lumbar vertebra.
Which are branches of the superior mesenteric artery?
The distal branches of the superior mesenteric artery (right colic, ileocolic, and middle colic) and the inferior mesenteric artery (sigmoid and left colic) supply the colon. They are also connected to each other by an intricate arterial arcade along the mesenteric border known as the Marginal Artery of Drummond.
