An action potential diminishes as it moves down an axon.

Large-diameter axons transmit action potentials much faster than do smaller axons.

Action potentials propagate in two directions along the axon.

An action potential is propagated when the influx of sodium ions into an axon causes negative charges to move away from sodium channels.
