Quizplus · Accepted Answer

Morphine and codeine exert analgesic properties that resemble those of the body's endorphins, which are natural pain-relieving chemicals produced by the body. They bind to and activate the opioid receptors, which are found in the brain, spinal cord, and other areas of the body involved in pain perception, resulting in a reduction of pain sensation.
