B) Polarization
C) Repolarization
D) Threshold

Question

Quizplus · Accepted Answer

Repolarization occurs when potassium ions diffuse out of a nerve cell and the inside of the cell again becomes more negative than the outside. Depolarization is the opposite process, when sodium ions move into the cell and the inside becomes more positive. Polarization refers to the resting state of the cell, when there is a potential difference between the inside and outside. Threshold is the level of depolarization required to trigger an action potential.
