How is an action potential propagated along an axon? View Available Hint(s) An efflux of potassium from the current action potential depolarizes the adjacent area. An influx of sodium ions from the current action potential depolarizes the adjacent area. Stimuli from the graded (local) potentials from the soma and dendrites depolarize the entire axon. Part B Why does the action potential only move away from the cell body? View Available Hint(s) The flow of the sodium ions only goes in one direction-away from the cell body The areas that have had the action potential are refractory to a new action potential. Part C The velocity of the action potential is fastest in which of the following axons? View Available Hint(s) a small unmyelinated axon a large unmyelinated axon a small myelinated axon
