Question

Quizplus · Accepted Answer

Endorphins are the neurotransmitters that act as the body's natural version of morphine. They are released in response to pain and can influence the perception of pain. Psychological factors, such as stress and mood, can also influence the release of endorphins. Substance P is another neurotransmitter that is involved in pain perception, but it does not have the same pain-relieving effects as endorphins. Serotonin and acetylcholine are neurotransmitters involved in other bodily functions, but not specifically related to pain perception.
