Involuntary muscle refers to muscles that are not under conscious control and perform actions automatically. This includes muscles that control various functions in the body without requiring a conscious thought to activate them, such as those found in the walls of internal organs and blood vessels.

Cardiac muscle, which specifically makes up the heart, and smooth muscle, which is found in various organs, are both types of involuntary muscle. While skeletal muscle is responsible for voluntary movements and allows us to move our limbs, it is not classified as involuntary. Therefore, the term "involuntary muscle" encompasses more than just cardiac muscle; it primarily represents the nature of these muscles in contrast to voluntary muscles.

This understanding is essential for recognizing how different muscle types function and their roles in the body, particularly in high-stress environments like corrections facilities, where an awareness of involuntary responses can help officers manage situations effectively.
