What does increased endogenous opioids do?

• A. Increases appetite
• B. Reduces pain and increases euphoria
• C. Causes tremor
• D. Decreases respiration

Answer: (B)

Endogenous opioids act as the body's natural painkillers and mood modulators. When their levels rise, they bind to opioid receptors in the brain and spinal cord, especially mu receptors, to dampen pain signaling and create a sense of well-being or euphoria. Mechanistically, they inhibit neurotransmitter release in pain pathways and can influence reward circuits, which explains the euphoric feeling. While high levels can depress respiration, the primary effect being asked is analgesia with a boost in mood. Tremor isn’t a typical outcome, and appetite changes aren’t the defining effect in this context.
