Question

Quizplus · Accepted Answer

The mu opioid receptor is responsible for the euphoric and analgesic effects of opiates, including morphine and heroin. Activation of the mu receptor also leads to sedation, respiratory depression, and physical dependence. The delta and kappa receptors also play a role in opioid signaling, but they are less involved in the typical opioid effects of euphoria and pain relief. The sigma receptor is not directly involved in opioid signaling but may be affected by long-term opioid use.
