The correct sequence of events during the generation and conduction of a nerve impulse along an axon is:
I. Rapid influx of Na⁺ into the axon.
II. Restoration of resting potential by outward diffusion of K⁺.
III. Stimulus application at a polarized membrane site.
IV. Reversal of polarity (depolarization) at the stimulated site.
V. Active transport of Na⁺ out and K⁺ into the axon by Na⁺/K⁺ pump.
