The flow of neurotransmitters into the synaptic cleft demonstrates which type of signaling?

• A. Chemical signaling
• B. Electrical signaling
• C. Thermal signaling
• D. Mechanical signaling

Answer: (A)

Neural communication across a synapse occurs through chemical signaling. neurotransmitters released into the synaptic cleft are chemical messengers that diffuse across the gap, bind to receptors on the postsynaptic neuron, and produce a response—often changing the postsynaptic membrane potential. This is distinct from electrical signaling, which relies on the direct flow of ions to propagate action potentials within neurons. Thermal signaling and mechanical signaling aren’t the primary mechanisms for transmitting messages between neurons in this context. So the flow of neurotransmitters into the synaptic cleft demonstrates chemical signaling.
