And no matter how high our stimulus is, no action potential can be generated in this section. And so our action potential does not actually move in a backward direction towards Arasoma and only moves towards our axon terminal. And this is shown in the following diagram. So our stimulus is applied to this section. If it's high enough, we basically have this propagation of the action potential take place and it only moves away from the soma away from the cell body and towards our axon terminal. So this is the mechanism by which our propagation of the action potential actually takes place.
