Opiates suppress pain by
A) mimicking the action of peptide transmitters in the central nervous system.
B) inhibiting the transmission of information from the brain to the spinal cord.
C) binding to chemoreceptors and controlling cellular secretions involved in pain detection.
D) inhibiting the signal carried from the site of the pain to the brain.
E) stimulating the release of steroid signalling hormones which override the pain receptors.

Question

Quizplus · Accepted Answer

Opiates work by mimicking the action of natural peptide neurotransmitters in the central nervous system, specifically those involved in pain control, such as endorphins. This mimicry allows them to bind to opioid receptors, reducing the perception of pain.
