Flashcards: Colon (anatomy)

The ascending colon is the part of the colon located between the cecum and the transverse colon.

The descending colon is the part of the large intestine from the splenic flexure to the beginning of the sigmoid colon.

Megacolon is an abnormal dilation of the colon (also called the large intestine).

The transverse colon is the longest and most movable part of the colon.

A colorectal polyp is a polyp (fleshy growth) occurring on the lining of the colon or rectum.

The sigmoid colon (pelvic colon) is the part of the large intestine that is closest to the rectum and anus.

Toxic megacolon (megacolon toxicum) is an acute form of colonic distension.

In human anatomy, the marginal artery of the colon, also known as the marginal artery of Drummond and artery of Drummond (named after Hamilton Drummond (1882 - 1925) a son of Dr|Sir David Drummond]] (1852-1932) an English physician), is a blood vessel that anastomoses (connects) the inferior mesenteric artery (IMA) with the superior mesenteric artery (SMA).

The middle colic artery is a branch of the superior mesenteric artery that mostly supplies the transverse colon.

The haustra (singular haustrum) of the colon are the small pouches caused by sacculation (sac formation), which give the colon its segmented appearance.

The teniae coli (also taeniae coli) are three separate longitudinal ribbons of smooth muscle on the outside of the ascending, transverse, descending and sigmoid colons.

The hindgut (or epigaster) is the posterior (caudal) part of the alimentary canal.

There are two colic flexures, or curvatures in the transverse colon.

The iliac colon is situated in the left iliac fossa, and is about 12 to 15 cm.
