Cardiac muscle consists of individual heart muscle cells (cardiomyocytes) connected by intercalated discs to work as a single functional organ or syncytium . By contrast, skeletal muscle consists of multinucleated muscle fibers and exhibit no intercalated discs . Intercalated discs support synchronized contraction of cardiac tissue . They occur at the Z line of the sarcomere and can be visualized easily when observing a longitudinal section of the tissue . </P> <P> Three types of cell junction make up an intercalated disc--fascia adherens, desmosomes and gap junctions . </P>
