WebOpioid receptors are found in the nervous system, where they are embedded in the outer membrane of nerve cells (neurons). When opioids attach (bind) to the receptors, the interaction triggers a series of chemical changes within and between neurons that lead to feelings of pleasure and pain relief. WebReceptors is a site where a drug binds and then brings about a physical response. Drugs are recognized by their targets via various types of interaction. Drugs binding at the same site …
