When a neuron depolarizes and begins an action potential,sodium ions move into the axon and then potassium ions move out of the axon.

Question

Quizplus · Accepted Answer

During depolarization and the start of an action potential, sodium ions move into the axon through voltage-gated channels. This causes a rapid depolarization of the membrane potential. As the action potential peaks, potassium ions move out of the axon through voltage-gated channels, causing repolarization of the membrane potential.
