And so, as soon as it gets to that sheath, no more action potential can actually travel through the cell membrane. Instead, that electric signal will propagate at a much quicker rate through the cytoplasm of the cell. So this is the cytoplasm, this is the outside region, these are the myelinated sheets, and these are the nodes of Ranveer. 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.
