Question

Quizplus · Accepted Answer

Sodium ions are responsible for the depolarization of the neuron, which is the first step in the firing process. If sodium is prevented from passing through the neuronal membrane, the neuron will not be able to fire. The refractory period is the period of time after a neuron has fired during which it is unable to fire again. This is due to the fact that the sodium channels in the neuronal membrane are inactivated during the refractory period.
