Illustration of fentanyl molecules (red) binding to the mu-opioid receptor (blue) in a cell membrane. Opioid receptors are found on nerve cells. When pain is detected by the body, endorphins are released and attach to the receptors, starting a reaction that modulates pain perception. Opioid drugs such as fentanyl mimic endorphins. | |
