splenic flexure

(left colic flexure, Griffith's point)

The bend where the transverse colon and descending colon meet in the upper left part of the abdomen.
It is the highest point that the colon reaches in the body. (It lies more cranial than the right colic flexure.)

It attaches to the left hemidiaphragm by the phrenicocolic ligament (sustentaculum lienis).
Phrenicocolic ligament is a fold of peritoneum, that goes from the splenic flexure to the diaphragm opposite the 10th and 11th ribs, passing below and serving to support the spleen.

(Blood supply)
• terminal branches of superior mesenteric artery
• inferior mesenteric artery
It prone to ischemic damage in cases of low blood pressure because it does not have its own primary source of blood.

(Innervation)
• vagus nerve: Generally provides parasympathetic fibers to the entire abdomen proximal to a point approximated by the splenic flexure of the colon. These fibers arise from the brain stem and, specifically, the dorsal motor nucleus of the medulla oblongata.
• superior mesenteric plexus: Provides sympathetic innervation to the cecum, appendix, ascending and transverse colon (near to the splenic flexure)
• inferior mesenteric plexus: Innervates the colon from the splenic flexure to the rectum.
• inferior hypogastric plexus: Also innervates the rectum.
