(flek'shur) [L. flexura, bending, winding]
1. A bend.
2. The state or quality of being flexed or bent.
3. Something flexed or bent.

anorectal flexure

The sharp forward bend at the anorectal junction as the rectum passes through the pelvic diaphragm muscles. This acute bend, which is normally maintained by the puborectalis sling muscles, helps to keep feces in the rectum. During defecation the pelvic diaphragm muscles relax (so the puborectalis sling relaxes) and the sharp bend between rectum and anus straightens; this makes the passage of feces from rectum to anus easier.

dorsal flexure

A convex curve in the thoracic area of the spine.

duodenojejunal flexure

A sharp curve at the meeting point of the jejunum and duodenum. The duodenojejunal flexure hangs from the diaphragm by a thin muscle, the suspensory muscle of the diaphragm.

hepatic flexure

The bend of the colon under the liver; the junction of the ascending and transverse colon.
Synonym: right colic flexure

left colic flexure

Splenic flexure.

right colic flexure

Hepatic flexure.

sigmoid flexure

An S-like curve (in the left iliac fossa) of the descending colon as it joins the rectum. Former name for sigmoid colon.
See: colon for illus

splenic flexure

The bend of the colon near the spleen; the junction of the transverse and descending colon. The splenic fixture is suspended from the diaphragm by the phrenocolic ligament, which passes over the lower part of the left kidney. Synonym: left colic flexure
