A. The rate of transmission of an action potential is directly related to the diameter of the axon.
B. Information about the intensity of a stimulus is conveyed by changes in the size of the action potential generated.
C. The resting potential is maintained by differential ion permeabilities and the sodium-potassium pump.
D. Once initiated, local depolarizations stimulate a moving wave of depolarization down the axon.
E. A stimulus to the neuron can either depolarize or hyperpolarize the neuronal membrane.
