_______ (reduction of the resting potential) of an axon until it reaches a threshold value opens voltage-gated sodium (Na⁺) channels, making the membrane completely _______ to sodium ions (Na⁺). The Na⁺ ions rush in, and the axon becomes briefly more positive inside than outside. This event is called an _______.

Question

Quizplus · Accepted Answer

Depolarization of the resting potential opens voltage-gated sodium channels, making the membrane permeable to Na⁺, leading to an action potential.
