Psych 464 Ch.11 Exam Questions and Answers| New Update with 100% Correct Answers
When you stub your toe on a hard object, the lingering ache you feel after the initial sharp pain
has worn off is caused by information being carried in slowly conducting unmyelinated
fibers.
All of the following are effects of the class of drugs called narcotic analgesics except diarrhea
Pain transmission in the spinal cord can be blocked by the action of inhibitory spinal
interneurons that release endorphins.
Some researchers believe that opiates exert their effects on reinforcement by affecting cell
bodies in the _______ that release _______. VTA; dopamine
Which of the following is not one of the ways Pert and Snyder confirmed that they had in fact
located and labeled opiate receptors? They demonstrated that the binding and the
physiological effects were completely irreversible.
What do we know about the structure of the opiate receptors from receptor cloning studies?
The receptors appear to be metabotropic.
CDC federal guidelines for pain control All of the above
Which statement about the effects of opiates on synaptic transmission is false? They cause
postsynaptic depolarization by opening potassium channels.
_______ is the natural ligand for the δ-receptor. Enkephalin
Nociceptors detect All of the above
, Methadone is an effective treatment for opiate drug abuse because it is cross-tolerant with
abused opiates, so it can reduce the effects of morphine and heroin with repeated use.
The naturally occurring opiates include thebaine, codeine, and heroin.
Which of the following is a larger propeptide that is broken down into smaller active opioids?
Pro-opiomelanocortin (POMC)

effect of some opiate medications/drugs. Which of the following is this therapeutic use/side
effect? Slowing of gastrointestinal function/motility
One common effect of increasing opiate dose is euphoria
Which statement about the history of opium is true? It has a long history of recreational
use.
Which statement about pain perception and opiate action at supraspinal levels is false? Pain
reduction at supraspinal levels is primarily mediated by δ-receptors.
Which finding provides evidence that opioid drugs enhance the brain reward system in animal
models? Administration of opioids lowers the electrical current threshold for self-
stimulation.
Both "early" and "late" pain are associated with neural activity in the secondary
somatosensory cortex.
What is the significance of the finding that a traditional acupuncture session produces the same
effect as a fake session (no needles penetrating the skin)? Acupuncture may produce
placebo effects
