Anal sphincter
The anal sphincter is made up of two sets of muscles called the "internal" and "external" sphincters. These muscles form a ring around the anus. When these muscles are working normally, they squeeze the anus shut so that gas and bowel movements cannot leak out.

View OriginalColonoscopy versus sigmoidoscopy
During a colonoscopy or a sigmoidoscopy, you lie on your side, and the doctor or nurse puts a thin tube with a camera into your anus (from behind). Then the doctor or nurse advances the tube into the rectum and colon. The camera sends video pictures from inside your colon to a television screen.
A colonoscopy allows the doctor to see the whole colon (shown in pink and green). A sigmoidoscopy allows the doctor to see only the last part of the colon (shown in green).
