Question

Quizplus · Accepted Answer

When an impulse passes from one neuron to the next, it passes from the output zone of one neuron (axon terminal) to the input zone of the next neuron (dendrite). This is known as synaptic transmission. The impulse triggers the release of neurotransmitters from the axon terminal into the synaptic cleft, which then bind to receptors on the dendrite, generating a new impulse. The other answer choices are incorrect.
