If a drug blocks chemical message at a synapse, what effect will it have on nervous coordination?

Answer and explanation

Correct answer: Transfer of the message to the next neuron will be disturbed

The governing concept is synaptic transmission. When an electrical impulse reaches the end of one neuron, chemicals called neurotransmitters cross the synaptic gap and stimulate the next neuron. If a drug blocks their release or action, the signal cannot pass normally, so the response may be delayed, weakened, or stopped. Therefore option A is correct. Options B, C, and D do not describe the specific effect of blocking a synapse.
