7 Written questions

6 Multiple choice questions

  1. -post amputation, absence of sensory info causes neurons in central nociceptive pathways to become overactive; maladaptive structural reorganization is found in the SC,
    thalamus, and cerebral cortex; there is overlap of cortical reprsentation that are normally separate (loss of sensory info lighting up pain matrix)
  2. -develop at nerve stump end, and tapping induces pain (Tinel's sign); tapping test at end of nerve creates a lot of pain
  3. -If peripheral sensory information is completely absent, CNS neurons in the nociceptive pathway become abnormally active
  4. - top-down regulation disturbed; antinociception is decreased and pronociception is increased resulting in increased pain
  5. -involve more than one nerve, such as diabetic neuropathy and Guillian Barre
  6. -Aspirin/ibuprofin decreases synthesis of prostaglandins
    preventing prostaglandins from sensitizing nociceptors.

6 True/False questions

  1. Massage-increases circulation th compression of tissue which decreases ischemic pain, a deficiency of blood (ischemia) results in a deficiency of 02 (hypoxia) which cause pain in tissue; pain from cramp is due to squeezing of capillaries & decreasing blood supply; when blood flow is interrupted,
    pain-stimulating chemicals accumulate; applied heat dilates blood vessels, increasing blood flow/02 and decrea
    sing the concentration of pain-stimulating substances; massage also simulates A-beta fibers thus activating the gating contrl mechanism

          

  2. Complex Regional Pain Syndrome- top-down regulation disturbed; antinociception is decreased and pronociception is increased resulting in increased pain

          

  3. Fibromyalgia-tenderness/stiffness of muscles, aching pain, increased stress/sllep disorders, secondary hyperalsia, allodynia; abnormal activation of pain matrix with amplification of signals

          

  4. Ephatic transmission-occurs in demyelinated areas - GB Syndrome

          

  5. Rhizotomy-cutting of a dorsal sensory nerve root

          

  6. Mononeuropathy-involve more than one nerve, such as diabetic neuropathy and Guillian Barre
