Station 8Number your paper 1-14. Put the following in the correct order.

A. A stimuli excites the neuron.B. Potassium channels on the neuron's membrane open.C. Potassium rushes out of the neuron.D. Resting potential is restored.E. Sodium channels in the membrane open.F. Sodium is pumped back to the outside of the neuron and potassium is pumped back

to the inside of the neuron.G. Sodium rushes into the neuron down the concentration gradient.H. Some ions sneak through the neuron's membrane to the other side, however, the

sodium potassium pump returns ions to their original positions.I. The inside of the neuron's membrane becomes positive for a period of time.J. The major positive ions inside the cell are potassium, whereas the major positive

ions outside the cell are sodium.K. The neuron is depolarized.L. The neuron is repolarized.M. The outside of the neuron's membrane has more positive ions than the inside of the

neurons membrane.N. This is known as resting potential; the neuron is inactive.
