The rectum is a portion of the end of the colon just before the anus and is controlled by involuntary muscles (smooth muscle). I believe the anal spincter or rear end opening has 2 types of muscles. The internal anal sphincter is involuntary fortunately and keeps us from social embarrassment. The external anal sphincter is voluntary and allows us to properly time the release of gas at the right moment in a conversation.
