Question

Quizplus · Accepted Answer

Opiates bind to receptors on presynaptic terminals of nociceptive afferents, which leads to inhibition of neurotransmitter release, ultimately resulting in pain relief. Inhibition of GABA, facilitation of substance P release, and stimulation of CGRP release are not mechanisms of action of opiates in the spinal cord.
