An action potential does not restimulate the adjacent membrane that was previously
depolarized because (select all that apply)
It is impossible for an action potential to be propagated along an axon toward the nerve cell body
The resting membrane potential of the axon is too high
The resting membrane potential of the axon is too low
✓ This area of membrane is absolutely refractory to depolarization
✓ Stimulation is inhibited by the myelin sheath
