What flexure is between ascending and transverse colon?
What flexure is between transverse and descending colon?
Longitudinal muscles of colon wall condensed into three bands..., begin at root of appendix and merge into continuous muscular layer at rectum.
What gathers colon into pouches called haustra?
Is the ascending colon retroperitoneal or intraperitoneal?
retroperitoneal - peritoneum only on anterior surface
What is in the appendix's mesentery (mesoappendix)?

transverse mesocolon (extends along inf. pancreas, and descending duodenum)
droplets of fatty mesentery project from the surface of colon (typically associated with taenia coli.
epiloic (omental) appendages
