Introduction
The colon can be divided into the following portions:
- Ascending
- Transverse
- Descending
Structure
- The ascending colon continues from the iluem at the ileocolic junction.
- It runs to the right of the cranial mesenteric artery in a caudal to cranial direction.
- At the cranial border of the mesentry it turns medially to become the transverse colon.
- The transverse colon runs from the right side of the abdomen to the left side of the abdomen.
- Cranial to the transverse colon is the stomach, and caudal to it is the small intestine and cranial mesenteric artery.
- The descending colon continues on from the transverse colon running caudally on the left from the level of (???).
- It then passes more medially as it enters the pelvic cavity
- Upon entering the pelvic cavity it is continued as the rectum.
