POSTERIOR MESENTERIC ARTERY

• Visceral unpaired.
• It arises from the ventral face of the aorta near its termination behind the origin of the spermatic arteries.
• It is related to the posterior mesenteric ganglion and the plexus encloses the vessel.
• It divides in to an anterior short colic branch to supply the terminal part of the colon and a posterior longer anterior haemorrhoidal branch to supply the rectum.
