The Proper Anatomical Order for the Divisions of the Colon

Question

The proper anatomical order for the divisions of the colon is:
A)descending, transverse, sigmoid, and ascending.
B)ascending, transverse, sigmoid, and descending.
C)sigmoid, ascending, transverse, and descending.
D)ascending, transverse, descending, and sigmoid.

Accepted Answer

The colon is divided into four main parts: the ascending colon, the transverse colon, the descending colon, and the sigmoid colon. The correct anatomical order starts with the ascending colon (which goes upwards on the right side of the abdomen), followed by the transverse colon (which crosses the abdomen from right to left), then the descending colon (which goes downwards on the left side), and finally the sigmoid colon (an S-shaped segment that connects to the rectum).
