Endorphin response works where?

Endorphin response works where?

• A. In the CNS
• B. In the PNS
• C. In the spinal cord only
• D. In muscle tissue

Answer: (A)

Endorphins modulate pain primarily by acting in the central nervous system. They bind to opioid receptors in the brain and spinal cord, which dampens the transmission of pain signals and changes how pain is perceived. This central action includes inhibiting neurotransmitter release in the spinal cord’s pain pathways and altering processing in brain regions involved in pain perception, such as the thalamus and cortex. While endorphins can be released into the bloodstream and have effects there, the most important analgesic effects come from their actions within the central nervous system. The peripheral nervous system or muscle tissue aren’t the main sites for this analgesic response, and limiting the effect to the spinal cord only would miss the brain’s role in modulating pain.
