Cardiac muscle cells or cardiomyocytes (also known as myocardiocytes or cardiac myocytes) are the muscle cells that make up the cardiac muscle (heart muscle) each myocardial cell contains myofibrils, which are specialized organelles consisting of long chains of sarcomeres, the fundamental contractile units of muscle cells. The specialized striated muscle tissue of the heart the myocardium cardiac-muscle noun (plural cardiac muscles)(anatomy) the striated and involuntary muscle.Both skeletal muscles and cardiac muscles contain striations among muscle cells and produce strong contractions, according to class notes from yale university striations occur in crossing, alternating light and dark bands produced by proteins that make muscles contract, according to dictionarycom.
