B) polarization
C) repolarization
D) threshold

Question

Quizplus · Accepted Answer

When potassium ions diffuse out of a nerve cell, the inside of the cell becomes more negative than the outside, which is known as repolarization. Depolarization occurs when sodium ions enter the cell, making the inside more positive than the outside. Polarization refers to the resting potential of a nerve cell before any ion movement occurs. Threshold is the minimum level of depolarization required to trigger an action potential.
