anterior cecal artery
posterior cecal 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 gives rise to the appendicular artery and anastomoses with the end of the superior mesenteric artery, the superior with the right colic artery. Supplies the cecum, ileum, and appendix.
The inferior branch of the ileocolic runs toward the upper border of the ileocolic junction and supplies the following branches:
- colic branch of ileocolic artery, which passes upward on the ascending colon - from the posterior branch of the inferior branch of the ileocolic artery
- ileocecal (some sources acknowledge this division while others do not)
