Peculiarities of topographic anatomy and crypt compartment of distal colon in Wistar rats

We studied distal colon of Wistar rats including descending transverse colon and rectum. Feature of distal colon in the left flexure are short mesenterium growing in size towards rectum, common mesenterium with small intestine attached to it on the right side and ligament forming left flexure and at...
