Which neurotransmitter is linked to pain control and to pleasure and is naturally produced in the brain?

• A. Endorphins
• B. Dopamine
• C. Acetylcholine
• D. Norepinephrine

Answer: (A)

Endorphins are the body's natural painkillers, providing analgesia by binding to opioid receptors in the brain and spinal cord. They’re also tied to pleasurable feelings, producing a sense of euphoria in situations like intense exercise or stress. Because they’re produced naturally in the brain (and by the pituitary), they function as endogenous opioids that both reduce pain and elevate mood. While dopamine is linked to reward and motivation, and acetylcholine and norepinephrine serve other roles (movement/memory and arousal, respectively), endorphins uniquely match the combination of pain control and pleasure.
