Remember, the nodes of Ranvir are gaps that occur at regular intervals between the segments of the myelin sheet. And these gaps contain a great number of sodium channels. So, as this electrocurrent moves into this node, what happens is this signals the depolarization process and the voltage gated sodium channels open up and our flux influx of sodium ions goes into our cell and that depolarize the cell and creates the action potential. Now, that basically amplifies our electric signal and sends it through the cytoplasm because the action potential cannot travel through this myelin native cell membrane. And so it really quickly travels to the next node, creates that depolarization, creates that action potential. Once again, that action potential cannot actually travel through the cell membrane.
