Reorder the following steps of the neural impulse to show the correct order
At rest the neuron is polarized with a positive outside and negative inside.
A stimulus opens an ion channel to allow for depolarization.
The depolarization opens more voltage channels to depolarize the the axon.
Repolarization begins when potassium starts to move out of the neuron.
The sodium-potassium pump allows the neuron to completely repolarize.
