Read the following statements that describe what happens as an impulse travels. What is the correct order in which the steps occur? 1) The impulse continues to travel down the axon away from the cell body. 2) Na + gates close and K + ions flow back out of the cell restoring the resting potential. 3) Gated K + and Na + channels are closed. The inside of the cell is slightly negative compared to the outside. 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 ...

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.
