Answer :
I believe that the order is 4,5,2,3. 1 can fit anywhere after the neuron receives a signal strong enough to start an action potential. Once an action potential is generated at voltage gated channels it results in a stimulus of surrounding neurons.
Answer:
4) The neuron receives a stimulus great enough to start an impulse.
5) Gated Na+ channels open. The net movement of Na+ ions into the cell produces the action potential..
2) Na+ gates close and K+ ions flow back out of the cell restoring the resting potential.
1) The impulse continues to travel down the axon away from the cell body.
3) Gated K+ and Na+ channels are closed. The inside of the cell is slightly negative compared to the outside.
