- formed mainly from branches from the aorticorenal plexus
- some contributions from the lumbar splanchnic nerves (sympathetic)
- minor contributions arise via the left and right hypogastric nerves from the inferior and superior hypogastric plexus (parasympathetic)
branches and supply: numerous small branches that distribute along the inferior mesenteric artery and its branches
- supplies the distal transverse colon, splenic flexure, descending colon, sigmoid colon and upper rectum
relations: those of the inferior mesenteric artery
