The myocardium is the thick, middle layer of the heart and is composed of cardiac muscle. Cardiac muscle is very unique because it possesses the characteristics of skeletal muscle AND smooth muscle. Skeletal muscle controls the voluntary movement of the body, while smooth muscle is responsible for the movement of all other body organs. The myocardium acts on its own, with no conscious effort.
