What is the definition of endorphins? a. neurotransmitters at the nociceptors b. transmitters for sensory impulses c. opiate-like blocking agents in the central nervous system d. pain-causing chemical mediators

What is the role of nociceptors? They are: a. pain receptors that are stimulated by thermal, chemical, or physical means b. spinal nerves that conduct impulses from specific areas of the skin c. responsible for the state of arousal with pain d. useful in localizing pain to a specific area of the body

Intractable pain is best defined as: a. pain that is perceived as occurring in an amputated limb b. severe pain that cannot be controlled by medication c. pain perceived as coming from a source other than the actual source d. pain coming from a specific dermatome
