Question

Quizplus · Accepted Answer

Only option C, action potential, refers to the brief electrical charge that travels down the axon of a neuron. The synapse refers to the junction between two neurons or between a neuron and a muscle cell. Agonist refers to a substance that activates a receptor to produce a response, and the refractory period is the brief period of time after an action potential where the neuron is unable to fire another action potential.
