ANATOMY

Detailed explanation-1: -Involuntary muscles are the muscles that contract or move without conscious control. The autonomic nervous system controls involuntary muscle movement. These muscles are generally associated with the viscera or internal organs that exhibit regular, slow contractions and involuntary actions.

Detailed explanation-2: -Smooth muscle, found in the walls of the hollow internal organs such as blood vessels, the gastrointestinal tract, bladder, and uterus, is under control of the autonomic nervous system. Smooth muscle cannot be controlled consciously and thus acts involuntarily.

Detailed explanation-3: -Skeletal muscles are under our conscious control, which is why they are also known as voluntary muscles. Another term is striated muscles, since the tissue looks striped when viewed under a microscope.

Detailed explanation-4: -What Is the Difference Between Voluntary and Involuntary Muscles? Voluntary muscles are skeletal muscles that contract and relax under conscious control. These muscles attach to bones and regulate movement of the body. Involuntary muscles, on the other hand, are not under conscious control.

Detailed explanation-5: -That is because some of your muscles are not under your conscious control. Those muscles are called involuntary muscles. Involuntary muscles are responsible for such essential activities as breathing and digesting food. The muscles that are under your conscious control are called voluntary muscles.
