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. 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.
