describe the structure and location of cardiac muscle fibres.
Cardiac muscle (heart muscle) is involuntary striated muscle that is found in the walls and histological foundation of the heart, specifically the myocardium. Cardiac muscle is one of three major types of muscle, the others being skeletal and smooth muscle.
There are three kinds of muscle tissues: Skeletal muscle is attached to bones and causes movements of the body. Cardiac muscle is found in the heart. Smooth muscle lines the walls of blood vessels and certain organs such as the digestive and urogenital tracts.
Cardiac (Heart) Muscle Tissue shows some of the characteristics of smooth muscle and some of skeletal muscle tissue. Its fibres , like those of skeletal muscle, have cross-striations and contain numerous nuclei. However, like smooth muscle tissue, it is involuntary.
