These contractile elements are just about similar to skeletal muscle. T (transverse) tubules penetrate from the floor plasma membrane, the sarcolemma, to the inside of the cell, healthy flow blood support permitting the electrical impulse to reach the interior. The T tubules are only found at the Z discs, natural blood flow support whereas in skeletal muscle, they are found at the junction of the A and that i bands. Therefore, Healthy Flow Brand there are one-half as many T tubules in cardiac muscle as in skeletal muscle.
