Answer:
The answer to this definition is: ACTION POTENTIAL
Explanation:
Action potential is a phenomenon in nervous system used to describe a change in electrical current that occurs when an impulse passes through a neuron or nerve cell. Action potential is induced when sodium (Na+) ions move from the extracellular environment into the intracellular environment.
Impulse travels across the axon of a neuron and thereby causes a difference in the electric potential i.e. - mv to + mv. This process, according to this question, whereby a change in electrical potential occurs due to the passage of an impulse through a nerve cell is termed ACTION POTENTIAL.
