And because we have such a great number of voltage gated channels, sodium voltage gated channels at the nodes of Ramvia, that will greatly increase our sensitivity to depolarization. So, to see what we mean by this, let's take a look at the following diagram. So, this diagram basically describes how our action potential moves along an axon that is myelinated, as shown in this diagram. So this is our cell body, these are the dendrites, and this is our axon. If we take a cross section of this axon, we basically get the following diagram. So, let's suppose we stimulate our axon hillock, as shown, and an action potential is generated at the axon hillock as it begins to move along, eventually it gets to the cell membrane that contains the myelin natived sheath.
