Coordination of their activity depends on an. Describe the structural characteristics of cardiac muscle cells. They are involuntary and intrinsically controlled striated branched and single nucleated.
Cardiac muscle cells or cardiomyocytes are the muscle fibers comprise the myocardium the middle muscular layer of the heart.
Starlings law of the heart Length-tension relationship. Highly coordinated contractions of cardiac muscle pump blood into the vessels of the circulatory system. Cardiac muscle forms atria and the heart ventricles. Cardiac muscle fibers are long branched cells shaped like cylinders joined end-to-end with one or two nuclei located centrally.
