19.2 Cardiac Muscle And Electrical Activity

In comparison with the giant cylinders of skeletal muscle, cardiac muscle cells, or cardiomyocytes, are considerably shorter with a lot smaller diameters. Cardiac muscle also demonstrates striations, the alternating pattern of dark A bands and light I bands attributed to the exact arrangement of the myofilaments and fibrils which can be organized in sarcomeres along the size of the cell (Figure 19.17a). These contractile components are nearly equivalent to skeletal muscle. T (transverse) tubules penetrate from the floor plasma membrane, the sarcolemma, CircuPulse Review to the interior of the cell, permitting the electrical impulse to succeed in the interior. The T tubules are solely found at the Z discs, whereas in skeletal muscle, they are discovered at the junction of the A and that i bands. Therefore, there are one-half as many T tubules in cardiac muscle as in skeletal muscle. As well as, the sarcoplasmic reticulum shops few calcium ions, so a lot of the calcium ions should come from exterior the cells.
