In fact, even though this section, let's say this section of the axon is covered with the myelin, our electric current can still travel through the cytoplasm to the cytosol of our cell and that's exactly how that signal will get from one node to the next node as we'll see in just a moment. So instead, the current moves through the cytosol of the axon until it reaches a part of the membrane that is not myelinated. And these gaps where we do not have any myelination as shown on this diagram and this diagram, so these are the gaps and these are the gaps here. These are known as nodes of Ranvia. So basically at the nodes of Ranvia, we do not have any myelination. In fact, we have a great number of sodium voltage gated channels.
