Question

Quizplus · Accepted Answer

A nerve action potential involves depolarization of the neuron membrane, which is triggered by the movement of sodium ions from the outside to the inside of the membrane. This depolarization is self-propagating, meaning that it spreads down the length of the neuron as an electrical signal. Therefore, all of the choices are correct.
