Question

Quizplus · Accepted Answer

When a neuron fires, it undergoes a brief electrical impulse called an action potential, which travels down the axon and triggers the release of neurotransmitters at the synapse. Choice A (synapsing) refers to the process of communication between neurons at the synapse, but does not specifically describe the firing of a neuron. Choices B (excitation) and C (inhibition) describe factors that can influence whether or not a neuron will fire, but do not specifically refer to the actual firing process itself.
