Which neuropeptide transmits the sensation of pain?

Question

Quizplus · Accepted Answer

Substance P is a neuropeptide that transmits the sensation of pain. It is released by neurons in response to tissue damage or inflammation and communicates pain signals to the brain. Enkephalins and endorphins are both involved in pain modulation and can act to reduce the sensation of pain, but they do not transmit the initial pain signal. Dopamine is a neurotransmitter involved in reward and motivation but is not directly related to pain transmission.
