    Question 49 1.67 pts Neurons have a negative resting potential. When they are conducting an action potential, the resting potential becomes more positive (depolarization) followed by a drop in the resting potential (repolarization). What is the order and direction of the ion movement responsible for these changes?

    Consider the following for problems 1 through 5: The concept of electric potential difference plays an important role in the human nervous system. A nervous impulse, for example, is an action potential that results from the temporal rising and lowering of the cell membrane potential, which in turn is caused by the equally temporal influx of sodium (Na+) ions into the cell. The sodium ions enter the cell through Hodgkin-Huxley channels, named after English physiologist/biophysicists Alan Hodgkin and Andrew Huxley....
