Biology a level- nervous system

does anyone have a good explanation as to how action potentials are conducted along a node of ranvier in a visual way - thanks

The action potential at a node of raniver 'jumps' from one to another, so from node to node. They have both potassium and sodium ion channels to depolarize the stimulus at one node and to polarized it at the other one. In short: the action potential is depolarized and polarized alternately. This makes it possible that an action potential is conducting in the neuron cell very fastly.
