Quizplus · Accepted Answer

Opiate drugs like morphine and codeine exert their pain-relieving effects by binding to specific receptors in the human nervous system that are normally stimulated by endogenous opiates, such as endorphins. These receptors are primarily found in areas of the brain and spinal cord involved in pain perception and modulation. Therefore, choice B is the correct option as it refers to the receptors for endogenous opiates.
