opioid system

the combination of delta, kappa, and mu opioid receptors found in the nervous system and gastrointestinal tract. Strongly involved in the experience of reward and the control of pain, this system is triggered both by opioids produced in the body (see endogenous opioid) and by naturally occurring or synthetic opioids administered exogenously.
