Aus Dornheim Anatomy
Position In situ
The appendix with appendix, the transverse colon and the sigmoid colon lie intraperitoneally and are attached to the wall of the trunk by a mesocolon. The transverse colon in particular is significantly more mobile than the rest of the large intestine due to its suspension, the mesocolon transversum.
Parts of the colon (ascending and descending colon) lie retroperitoneally and are directly fused to the trunk wall. The same applies to the upper rectum. The end of the rectum and the anal canal lie extraperitoneally outside the abdominal cavity.
The right colonic flexure lies lower than the left flexure due to the right liver lobe taking up more space. The ascending colon lies more ventrally than the descending colon.
