Question

In the normal course of an action potential,____.​

Quizplus · Accepted Answer

During an action potential, the concentration of sodium remains much more concentrated outside the neuron compared to inside the neuron. This occurs because the membrane is selectively permeable, allowing only certain ions to pass through. Sodium channels open briefly during the depolarization phase, allowing sodium ions to rush inside the neuron and depolarize the membrane potential. However, the channels then close, preventing further influx of sodium until the membrane potential returns to resting levels.
