ileocolic artery

The Ileocolic Artery is the lowest branch arising from the concavity of the superior mesenteric artery. It passes downward and to the right behind the peritoneum toward the right iliac fossa, where it divides into a superior and an inferior branch; the inferior anastomoses with the end of the superior mesenteric artery, the superior with the right colic artery. Supplies the cecum, ileum, and appendix. [WP,unvetted]. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the ileocolic artery connects to

The atlas records 4 typed relationships for it, across 2 kinds of connection. a kind of artery.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the ileocolic artery. Only a minority of structures carry those edges here, so an empty answer means nothing has been recorded — not that there is nothing to record.

Questions

Where is the ileocolic artery?

It sits within the cardiovascular system. Only the system is known. The position shown carries almost no spatial information.

What does the ileocolic artery connect to?

A kind of: artery.

Is the ileocolic artery the same in other species?

Leumas holds the same relationship vocabulary for every species it carries, so where another dataset records this structure you can put the two side by side on /compare.
