Meckel's Diverticulum, a photograph of a gastrointestinal tract abnormality (in the adult) due to midgut developmental abnormality. The abnormality is shown as the blind-ended tube lower right of image.
This abnormality is a very common (incidence of 1–2% in the general population) and occurs from the improper closure and reabsorption of the yolk stalk (vitelline duct, omphalomesenteric duct). This transient connection lies between the early midgut region and the yolk sac.
Named after Johann Friedrich Meckel (1781 – 1833) (the younger) a German anatomist who identified the abnormality origin in 1820.
