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.

What is the difference between a voluntary muscle and an involuntary muscle?

A voluntary muscle is one you must consciously choose to move, such as when pointing your finger or picking up a glass. An involuntary muscle is one that moves without you choosing to move it, such as heart muscle, and muscles involved in reflexes such as eye blinking.The difference between voluntary and involuntary muscles is (involuntary muscle)when you move without you choosing to move it and (voluntary muscle) that is when you can choose a muscle to move with.Voluntary muscles are consciously moved. Involuntary muscles are not consciously moved, smooth muscles and cardiac muscles are examples of involuntary muscles. When a muscle is both voluntary and involuntary it is considered voluntary.
