Which term describes tiny gaps between dendrites and axons of different neurons?

• A. Synapses
• B. Axons
• C. Nodes of Ranvier
• D. Dendrites

Answer: (A)

Communication between neurons occurs at synapses, the contact points where the axon terminal of one neuron meets the dendrite or cell body of another. The small space between them, the synaptic cleft, is what allows signaling to pass from one neuron to the next, typically via neurotransmitters in chemical synapses. So the term for these tiny gaps is synapses, capturing both the junction and the gap that enables neuronal communication. Axons are the long fibers that send signals, dendrites are the receivers, and the nodes of Ranvier are gaps in the myelin along an axon—not the gaps between neurons.
