The regeneration of action potential is called "propagation." It involves the transmission of the action potential along the length of the neuron's axon.
saltatory conduction Saltatory conduction is derived from the Latin word saltare, which means leaping
As the action potential passes an area on the axon, sodium channels are closed, preventing influx of more sodium ions. At the same time, voltage-sensitive potassium channels open, allowing the membrane potential to fall quickly. After this repolarization phase, membrane permeability to potassium remains high, allowing for the "afterhyperpolarization" phase. During this entire period, while the sodium ion channels are forced closed, another action potential cannot be generated except by a much larger input signal. This helps to prevent the action potential from moving backwards along the axon.

action potential
This is called action potential. Action potential is the change in electrical potential that occurs between the inside and outside of a nerve or muscle fiber when it is stimulated, serving to transmit nerve signals.
The structure in the neuron that accelerates the transmission of the action potential is called the myelin sheath.

Action potential is a neural impulse.
five second silence
It is called saltatory conduction. This describes the "jumping" of an action potential from node to node on a myelinated axon.
