Multiple Choice

An action potential does not re-stimulate the adjacent membrane that was previously depolarized because

C) the resting membrane potential of the axon is too positive.
D) the resting membrane potential of the axon is too negative.
E) that area of the membrane is in the absolutely refractory period.
