Transverse tubules (T-tubules) are invaginations of the plasma membrane that deeply penetrate into the muscle cell, allowing for the propagation of the action potential from the surface of the cell to the interior. This ensures that the membrane potential change is translated into the depth of the cell and ultimately leads to muscle contraction.
