Illustration of morphine (left, red) and fentanyl (right, red) molecules binding to mu-opioid receptors (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 morphine and fentanyl mimic endorphins. | |
