Similarity of the colon and its mesentery and vessels in the 10 week embryo and the adult. Ventral views showing the entire colon (panel a), the distal colon with its mesentery (panel b), the entire mesocolon (panel c), and the winding staircase appearance of the branches of the superior mesenteric artery (panel d) of a 10.0 week (s1507) embryo. Note presence of the colic bend (*; future splenic flexure) and absence of hepatic bend. Scale bar unit: μm. Panel e shows, for comparison, the position of the colonic mesentery in the adult, with the parts of the mesocolon of the ascending and descending colon that have merged with the posterior body wall shown in light and dark purple, respectively
