Transcription
HelpHippo: Help Support the Hippocratic Oath Our previous tutorial covered arteries coming directly off the abdominal aorta, and mentioned three big subcomplexities: CSI. This tutorial covers I for inferior Mesenteric Artery. "Inferior" reminds you of LeSS. Left colic artery Sigmoidal branches Superior rectal artery The left colic artery supplies the left colon. The sigmoid branches supply the sigmoid colon And the superior rectal artery supplies the rectum. LeSS is much LeSS complicated than the celiac trunk and superior mesenteric arteries.

Structure
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
The middle rectal artery supplies the rectum above the pectinate line.[2]
