Some painkillers prevent neurotransmitters binding to receptors in a synapse. Explain how a signal is transmitted at a synapse and how the painkillers reduce the pain felt by the person

Signal transmission at the synapse.

Explanation:

At the synapse, an electrical signal arrives at the pre-synaptic terminal an triggers vessicles to release neurotransmitters into the synaptic cleft.

These neurotransmitters activate receptors in the post-synaptic neuron and produce electrical signals.

Pain killers work by by preventing damaged or injured cells from producing prostagladins. Prostagladin is released when cells in the body are injured or damaged.

the principles and empirical processes of discovery and demonstration considered characteristic of or necessary for scientific investigation, generally involving the observation of phenomena, the formulation of a hypothesis concerning the phenomena, experimentation to test the hypothesis, and development of a conclusion that confirms, rejects, or modifies the hypothesis.

this is more of a statement than a question. is there answers to go along with this, or is it opinion based?
