State
The action potential is the rapid electrical spike that travels down the axon once the threshold of excitation is crossed.
Show
Sodium floods into the axon, the charge spikes positive, and the spike sweeps toward the terminal buttons.
Watch for
The action potential does not travel like electricity in a wire. It is regenerated at each point along the axon.
