The two types of ions that control neuron firing are:
A) nitrogen and calcium
B) calcium and sodium
C) sodium and potassium
D) potassium and magnesium

Question

Quizplus · Accepted Answer

Sodium and potassium ions are the two types of ions that control neuron firing. Sodium ions cause depolarization and potassium ions cause repolarization, together producing an action potential that allows for the transmission of signals in the nervous system. Nitrogen and magnesium are not involved in the process of neuron firing, and while calcium ions do play a role in neuron function, they are not the primary ions responsible for controlling neuron firing.
