Voluntary muscles are those which are under conscious control, which means under the control of the nervous system. This includes the skeletal muscles that attach to the bones and skin. The skeletal muscles allow thebody to move by contracting and relaxing against bones and skin. They also maintain posture in the body. They attach to bones by connective tissue called tendons. Skeletal muscle cells are long cells that appear striated. They are also multinucleated. The cells have several nuclei located in cytoplasm known as the sarcoplasm
Involuntary muscle is under unconscious control, which means under the control of the autonomic nervous system. These muscles contract without us being aware of it. Involuntary muscle includes: the smooth muscles that line organs, as well as the cardiac muscle of the heart. Smooth muscle cells are tapered at the ends and do not contain striations, they also contain a central nucleus.These cells contract slowly, and line all the organs of the body, including blood vessels.
