What is the junction between two neurons where neurotransmitters are released and received, enabling neural communication?

• A. Dendrite
• B. Synapse
• C. Axon
• D. Myelin sheath

Answer: (B)

The synapse is the site where neurons communicate. It’s the junction where the axon terminal of the sending neuron releases neurotransmitters into the tiny gap (the synaptic cleft), and receptors on the receiving neuron pick up those chemicals to continue the signal. This chemical transmission allows the electrical impulse to move from one neuron to the next, with the neurotransmitters producing either an excitatory or inhibitory effect depending on the receptors. Think of the other parts: a dendrite is where signals are received by a neuron, not where the actual communication bridge sits. An axon carries signals away from the cell body toward the synapse. The myelin sheath insulates the axon to speed up transmission, but it isn’t the site of neurotransmitter release and reception.
