Where do two or more neurons interact but do not touch?

• A. Axon
• B. Dendrite
• C. Synapse
• D. Reuptake

Answer: (C)

Two neurons interact without touching at a synapse, a specialized junction between them. In a typical chemical synapse, the sending neuron releases neurotransmitters into the tiny gap, called the synaptic cleft, and these chemicals cross over to bind receptors on the receiving neuron, transmitting the signal. This setup lets neurons communicate while remaining physically separate, which allows for modulation and precise control of signaling. The axon is the part that carries impulses away from the neuron's cell body to the synapse, while the dendrite is where the next neuron receives signals. Reuptake is the process of reabsorbing neurotransmitters after their release, helping to terminate the signal rather than serving as the site of the interaction itself.
