<br>In comparison with the giant cylinders of skeletal muscle, cardiac muscle cells, or cardiomyocytes, are significantly shorter with much smaller diameters. Cardiac muscle also demonstrates striations, the alternating pattern of darkish A bands and light I bands attributed to the precise association of the myofilaments and fibrils which are organized in sarcomeres along the size of the cell (Figure 19.17a). These contractile elements are nearly an identical to skeletal muscle. T (transverse) tubules penetrate from the surface plasma membrane, the sarcolemma, to the interior of the cell, allowing the electrical impulse to achieve the interior. The T tubules are solely found on the Z discs, whereas in skeletal muscle, they are discovered on the junction of the A and i bands.
