← Human Body & HealthWhich consequence results when reuptake of serotonin is excessively inhibited?
A)Prolonged postsynaptic receptor activation✓
B)Decreased presynaptic neurotransmitter synthesis
C)Reduced vesicular neurotransmitter storage
D)Enhancement of glial cell neurotransmitter uptake
💡 Explanation
Prolonged postsynaptic receptor activation occurs because inhibition of serotonin reuptake prevents the clearance of the neurotransmitter from the synaptic cleft, therefore intensifying and extending its effect on the target neuron, rather than glial involvement.
