Number 3 on the graph represents the action potential, which is the electrical impulse that travels down the axon of a neuron. The action potential is characterized by a rapid depolarization phase (seen as the upward spike on the graph) followed by a repolarization phase (seen as the downward slope back to the resting potential). The threshold is the level of depolarization required to trigger an action potential, and the resting potential is the stable negative charge maintained by the neuron when it is not transmitting a signal.
