Cecum is intraperitoneal even though it's part of the ascending colon

azibird  How were we supposed to know this? Thanks for the clarification. I picked cecum because FA says Crohn is usually the terminal ileum and colon, so I figured cecum would be the most likely vs the descending colon. +10  
kevin  Yeah that's what I thought at first too. Figuring it was a tricky question, I went with descending colon because 1) ascending and descending are retroperitoneal, so we know the latter is for sure right, and 2) cecum has it's own name (ie it's different than the ascending colon), so it probably isn't retroperitoneal in that regard. You can remember ascending and descending are retroperitoneal by remembering the greater omentum wraps around the transverse colon and from anatomy lab that there's a mesoappendix, mesocecum, etc (peritoneal) +
