Marginal artery of the colon
(重定向自Marginal artery of Drummond)


In human anatomy, the marginal artery of the colon, also known as the marginal artery of Drummond and artery of Drummond (named after 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). It is sometimes absent, as an anatomical variant.
