This is often completed initially because of the nucleus raphe magnus sending serotoninergic neurons to neurons within the dorsal cord, that in turn secrete enkephalin to the interneurons that carry pain notion.[15] Enkephalin capabilities by binding opioid receptors to trigger inhibition with the publish-synaptic neuron, Therefore inhibiting pain.[eleven] The periaqueductal gray also has opioid receptors which describes on the list of mechanisms by which opioids like morphine and diacetylmorphine show an analgesic influence.
