Quizplus · Accepted Answer

When a neuron receives a stimulus, sodium channels open and allow sodium ions to enter the neuron, which creates a positive charge within the cell. This positive charge triggers the release of neurotransmitters from the axon terminals. The diffusion of sodium out of the neuron and the closing of sodium channels occur during the repolarization phase of the action potential, which follows the initial depolarization phase.
