Quizplus · Accepted Answer

The term synapse refers specifically to the space between neurons where they communicate with each other through the release of neurotransmitters. Receptor sites are specific areas on the membrane of the receiving neuron where the neurotransmitter molecules bind. The synaptic knob, also known as the axon terminal, is the structure at the end of the presynaptic neuron that releases the neurotransmitter molecules.
