They stimulate opioid receptors in the central nervous system and peripheral tissues
Which of the following are endogenous natural opioid peptides?
Endorphins, enkephalins, and dynorphins
Which opioid receptor type is primarily responsible for respiratory depression caused by morphine?
μ (mu) receptors
What is the primary effect of stimulating κ (kappa) opioid receptors?
Spinal analgesia and miosis
Which statement about substance P is correct in the context of morphine's mechanism of action?
Morphine inhibits the release of substance P, reducing pain sensation
Which of the following side effects is NOT directly related to opioid receptor stimulation by morphine?
Hyperthermia (increased body temperature)
Learn about how morphine and related compounds stimulate opioid receptors in the central nervous system and peripheral tissues to modulate pain sensation. Discover the role of endogenous natural opioid peptides such as endorphins, enkephalins, and dynorphins in binding to these receptors and regulating neurotransmitter release.
