Compared to the enormous cylinders of skeletal muscle, cardiac muscle cells, or cardiomyocytes, are considerably shorter with a lot smaller diameters. Cardiac muscle also demonstrates striations, the alternating sample of darkish A bands and gentle I bands attributed to the precise arrangement of the myofilaments and fibrils which might be organized in sarcomeres along the length of the cell (Figure 19.17a). These contractile elements are nearly identical to skeletal muscle. T (transverse) tubules penetrate from the surface plasma membrane, the sarcolemma, to the inside 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're found 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 most of the calcium ions must come from exterior the cells.

Running vertically down the Z-line is a small tube known as the transverse or T-tubule, which is actually a part of the cell membrane that extends deep contained in the fiber. Contained in the fiber, stretching along the long axis between T-tubules, is a membrane system called the sarcoplasmic reticulum, which shops and releases the calcium ions that set off muscle contraction. The thick and thin filaments do the precise work of a muscle, and the best way they do that is pretty cool. Thick filaments are product of a protein called myosin.
