7 Written questions

6 Multiple choice questions

  1. -decrease production of neurotransmitters that transmit pain
  2. -If peripheral sensory information is completely absent, CNS neurons in the nociceptive pathway become abnormally active
  3. -Aspirin/ibuprofin decreases synthesis of prostaglandins
    preventing prostaglandins from sensitizing nociceptors.
  4. -tenderness/stiffness of muscles, aching pain, increased stress/sllep disorders, secondary hyperalsia, allodynia; abnormal activation of pain matrix with amplification of signals
  5. -develop at nerve stump end, and tapping induces pain (Tinel's sign); tapping test at end of nerve creates a lot of pain
  6. - (Sypatheric Reflex Dystrophy) abnormal response to trauma leading to limb disuse; disuse of limb precipitates an increase in levels of neurochemicals that cause peripheral inflammation, along with a decrease in sympathetic regulation of blood flow &swating; symptoms include pain, vascula changes, atrophy affecting entire hand/foot, red/pale skin, excessive sweating, edema, late stage dry/cold skin, muscle atrophy and osteoporosis.

6 True/False questions

  1. Cordotomy-cutting of a dorsal sensory nerve root


  2. Sympathectamy-decrease production of neurotransmitters that transmit pain


  3. 3) The Pain Matrix-develop at nerve stump end, and tapping induces pain (Tinel's sign); tapping test at end of nerve creates a lot of pain


  4. Phantom Limb Pain-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)


  5. 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


  6. Mononeuropathy-involves one nerve (median nerve or ulna nerve compression)
