The action potential of a neuron:

Question

TuteeHUB · Accepted Answer

declines in amplitude as it moves along the axon

TuteeHUB · Answer

is initiated by efflux of Na+

TuteeHUB · Answer

is terminated by efflux of K+

TuteeHUB · Answer

results in transient reversal of the concentration gradient of Na+ across the cell membrane

TuteeHUB · Answer

is not associated with any net movement of Na+ or K+ across the cell membrane
