WebPropagation of action potential An action potential is generated in the body of the neuron and propagated through its axon. …. The action potential generates at one spot of the cell membrane. It propagates along the membrane with every next part of the membrane being sequentially depolarized. WebThe action potential is unidirectional. It will go from the hillock (area where the axon starts) to the terminus (end of the axon near the synapse) in a wave like manner. He was saying that the reason for this is because the membrane is hyper polarized for a while after the action potential has past (more negative then the resting potential).
