colon descendens

Entire descending colon

Definitions

The descending colon of humans passes downward through the left hypochondrium and lumbar regions, along the lateral border of the left kidney. At the lower end of the kidney it turns medialward toward the lateral border of the psoas muscle, and then descends, in the angle between psoas and quadratus lumborum, to the crest of the ilium, where it ends in the sigmoid colon. The peritoneum covers its anterior surface and sides, and therefore the descending colon is described as retroperitoneal. (The transverse colon and sigmoid colon, which are immediately proximal and distal, are intraperitoneal). Its posterior surface is connected by areolar tissue with the lower and lateral part of the left kidney, the aponeurotic origin of the transversus abdominis, and the quadratus lumborum. It is smaller in caliber and more deeply placed than the ascending colon. It has a mesentery in 33% of people, and is therefore more frequently covered with peritoneum on its posterior surface than the ascending colon (which has a mesentery in 25% of people). However, it is less likely to undergo volvulus than the ascending colon. In front of it are some coils of small intestine. [WP,unvetted]. The portion of the colon between the left colic flexure and the sigmoid colon at the pelvic brim; the portion of the descending colon lying in the left iliac fossa is sometimes called the iliac colon.
