epsp's & IPSP's
Every time neurotransmitter is released from the presynaptic neuron it generates an excitatory post synaptic potential(EPSP) in the postsynaptic neuron. When the EPSP is greater than the threshold for excitation an action potential is generated.
When a stimulus stimulates a neuron above the threshold, the action potential is generated.
Action potential
The areas that have had the action potential are refractory to a new action potential.

I belive the size of the axon potential remains constant at a depolarisation of +40 mv and a resting potential of -70mv for most nerves. The frenquency of action potentials is the factor that determines the strength of the nerve impulse.
"how long it takes for the voltage-gated Na+ channels to reactivate at the end of an action potential"
It creates an action potential
This is called action potential. Action potential is the change in electrical potential that occurs between the inside and outside of a nerve or muscle fiber when it is stimulated, serving to transmit nerve signals.
When a stimulus stimulates a neuron above the threshold, the action potential is generated.
Curare does NOT create an action potential. It binds to nicotinic acetylcholine receptors (which are primarily excitatory), and prevents the formation of an action potential.
It doesn't. I prevents an action potential from forming.

Length, not caliber, determines action size
