Quizplus · Accepted Answer

Blocking postsynaptic receptors prevents neurotransmitters from binding to these receptors, thereby diminishing their effects on the postsynaptic neuron. This reduces the intended action of the neurotransmitter, such as inhibiting or exciting the neuron, leading to a decrease in the neurotransmitter's effects.
