← Human Body & HealthIf a drug prevents reuptake of neurotransmitters at inhibitory synapses in the spinal cord, which consequence follows?
A)Reduced sensory neuron firing
B)Enhanced inhibitory postsynaptic potentials✓
C)Increased action potential propagation speed
D)Decreased neurotransmitter synthesis
💡 Explanation
Blocking reuptake prolongs neurotransmitter presence in the synaptic cleft, therefore enhancing the inhibitory postsynaptic potentials because the neurotransmitter continues to bind to receptors. This effect is potentiation, rather than reducing firing through other mechanisms or affecting synthesis.
