6 Multiple Choice Questions

  1. -develop at nerve stump end, and tapping induces pain (Tinel's sign); tapping test at end of nerve creates a lot of pain
  2. -occurs in demyelinated areas - GB Syndrome
  3. -avultion of afferent roots (MVA neck flexion injury that causes avultion of brachial plexus dorsal roots); causes burning pain in the area of sensory loss
  4. -If peripheral sensory information is completely absent, CNS neurons in the nociceptive pathway become abnormally active
  5. -decrease production of neurotransmitters that transmit pain
  6. -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)

6 True/False Questions

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

          

  2. Sympathectamy- partial excision of synpathetic nerves or ganglia

          

  3. 1) PNS-If peripheral sensory information is completely absent, CNS neurons in the nociceptive pathway become abnormally active

          

  4. 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

          

  5. Complex Regional Pain Syndrome- (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. Rhizotomy-severing of the spinothalamic tract
