Where was capsaicin injected? - ✔✔The paw
What type of sensory fibers are most affected by capsaicin? - ✔✔C fibers
What does "hyperalgesia" mean? - ✔✔Increased sensitivity to pain
What are von Frey stimuli? - ✔✔Monofilaments
In reference to the assigned article, what is "central sensitization?" - ✔✔Pain felt at parts of
the paw away from the capsaicin injection site
Which one of the following represents a conclusion from the assigned article? -
✔✔Electrocacupuncture appears to operate via an opioid mechanism
What was the main conclusion of experiment 1 in the assigned article? - ✔✔Acupoints on
the front and hind leg were effective in relieving pain in the hind paw.
This study concluded that electroacupunture greatly reduced capsaicin-induced secondary
hyperalgesia. What does this mean? - ✔✔Rats felt less pain after EA
What was the main conclusion from experiment 3 in the assigned article? - ✔✔Endogenous
opioids mediate the effects of electroacupuncture.
Based on this study, the effects of electroacupunture on central pain sensitivity are most likely
due to ________________? - ✔✔Both mu and delta receptors

following body parts does NOT have a greater cortical representation on the sensory
homonculus than the foot? - ✔✔Chin
Which of the following situations is most likely to occur with a defective endogenous opioid
system? - ✔✔Opioids will bind to receptors less frequently, which increases the perception
of pain
Which of the following statements correctly ascribes the type of sensitization to the type of
hyperalgesia? - ✔✔Peripheral sensitization manifests as primary hyperalgesia and central
sensitization manifests as secondary hyperalgesia
Which of the following statements is not a dimension of pain? - ✔✔Behavioral-selective
Which receptor in the primary sensory neuron does EA inhibit? - ✔✔NMDA

nerve stimulation (TENS)
