Answer :
Action Potential is a very brief shift in a neurons electrical charge that travels along an axon.
The electrical gradient across the plasma membrane of a resting neuron abruptly reverses during a nerve impulse. A charge reversal is known as an action potential.
The process starts when the neuron gets a chemical signal from an additional cell or another kind of stimulation. A cascade of action potentials will occur down the axon if the stimulation is powerful enough to achieve threshold.
This charge reversal ripples down the neuron's axon very quickly as an electric current. A nerve impulse is an all-or-nothing reaction that is determined by whether or not the stimulus input was powerful enough to approach threshold. When a neuron reacts, it replies totally. A higher stimulus does not result in a stronger impulse.
