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.ardiac muscle cells, unlike most other tissues in the body, rely on an available blood and electrical supply to deliver oxygen and nutrients and remove waste products such as carbon dioxide. The coronary arteries help fulfill this function.
Cardiac muscles are the muscles of the heart. They are self-contracting, autonomically regulated and must continue to contract in rythmic fashion for the whole life of the organism. Hence they have special features. The cells are Y shaped and are shorter and wider than skeletal muscle cells.
