In myelinated axons,the gated ion channels that produce an action potential are concentrated at the nodes of Ranvier.Just as taking giant steps during a game of "Simon Says" is most efficient,so ion exchange only at the nodes makes the action potential travel faster in nonmyelinated axons.This mode of conduction is called saltatory conduction,meaning that the action potential "jumps" from node to node.See Figure 27.3.
