Question

Quizplus · Accepted Answer

Endorphins are natural painkillers produced by the body. Medications that relieve pain often work by mimicking the effects of endorphins, which bind to the same receptors in the brain and nervous system. Dopamine, serotonin, and GABA are involved in other functions such as mood regulation and communication between neurons, but they do not play a direct role in pain relief.
