Quizplus · Accepted Answer

Synaptic vesicles are the saclike structures found inside the synaptic knob that contain neurotransmitters. Axon terminals are the end of the axon where neurotransmitters are released. Synapses refer to the gap between two neurons where neurotransmitters travel. Receptor sites are specific locations on the postsynaptic neuron where neurotransmitters bind. Therefore, the best choice is C - synaptic vesicles.
