Quizplus · Accepted Answer

Endorphins are the neurotransmitters involved in both pain perception and pain relief. They bind to the same receptors as opioids, such as morphine, and can activate the brain's reward system to block pain signals. GABA is an inhibitory neurotransmitter involved in regulating anxiety, ACh is involved in muscle contraction and cognitive functions, and dopamine is involved in reward and motivation.
