The arrangement of the transverse and descending colon is similar to that of the dog and cat, but the ascending colon is different.
The arrangement of the transverse and descending colon is similar to that of the dog and cat, but the ascending colon is different.
The ascending colon is elongated and coiled to form a cone-shaped organ. The base of the cone is attached to the dorsal abdominal wall and the apex points ventrally. The position of the ascending colon varies with filling of the [[Monogastric Stomach - Anatomy & Physiology|stomach]]. From the [[Caecum - Anatomy & Physiology|caecum]], there are clockwise centripetal turns to the apex of the cone. Then the centrifugal turns run anti-clockwise on the inside of the cone. Centripetal turns have two taenia, whilst centrifugal turns have none.

*Mucosa has a columnar epithelium.
**Mucosa is thick and has long glands.
*Submucosa has large lymphatic nodules which may interrupt the lamina muscularis.
*Lamina muscularis is incomplete.
