Quizplus · Accepted Answer

Endorphins are known to act as natural painkillers in the body, and their release can be influenced by psychological factors such as mood, stress, and expectations. They bind to the same receptors as drugs like morphine, reducing the perception of pain. Substance P is a neuropeptide that is involved in transmitting pain signals to the brain, while serotonin and acetylcholine have other functions in the body and are not directly related to pain perception.
