Anatomical terminology |
The middle rectal artery is an artery in the pelvis that supplies blood to the rectum.
Structure[edit]
The middle rectal artery usually arises from the internal iliac artery.[1] It is distributed to the rectum above the pectinate line.[2] It anastomoses with the inferior vesical artery, superior rectal artery, and inferior rectal artery.[2]
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.
Function[edit]
The middle rectal artery supplies the rectum above the pectinate line.[2]
