Internal iliac artery, showing branches, including middle rectal artery

The middle rectal artery usually arises from the internal iliac artery. It is distributed to the rectum above the pectinate line. It anastomoses with the inferior vesical artery, superior rectal artery, and inferior rectal artery.

In males, the middle rectal artery may give off branches to the prostate and the seminal vesicles. In females, the middle rectal artery gives off branches to the vagina.
