The action potential of a neuron
a. is initiated by efflux of Na+
b. is terminated by efflux of K+
c. declines in amplitude as it moves along the axon
d. results in a transient reversal of the concentration gradient of Na+ across the cell membrane
e. is not associated with any net movement of Na+ or K+ across the cell membrane
