Question

Quizplus · Accepted Answer

The movement of ions across the membrane (specifically sodium and potassium ions) generates a current that flows down the axon of a neuron during an action potential. This movement of ions results in a change in the charge inside and outside of the neuron, allowing for the transmission of electrical signals.
