What term describes the junction between two neurons across which neurotransmitters travel?

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

Answer: (C)

Neurons communicate at a junction called the synapse. This is the space where chemical signals—neurotransmitters—travel from the sending neuron to the receiving neuron, crossing the gap in the synaptic cleft and activating receptors on the next cell. That chemical transfer across the junction is what defines a synapse.

The other parts play different roles: dendrites are the branching receivers that collect incoming signals, the axon carries electrical impulses away from the cell body toward the synapse, and the soma (cell body) houses the neuron's core machinery.
