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. - partial excision of synpathetic nerves or ganglia
  3. -develop at nerve stump end, and tapping induces pain (Tinel's sign); tapping test at end of nerve creates a lot of pain
  4. -Aspirin/ibuprofin decreases synthesis of prostaglandins
    preventing prostaglandins from sensitizing nociceptors.
  5. -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
  6. -involves one nerve (median nerve or ulna nerve compression)

6 True/False Questions

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

          

  2. 2) CNS-a. Injury or disease of peripheral nerve
    -b. A complete nerve section results in lack of sensation from that nerve's receptive field, and sometimes paresthesia (prikling and tingling pain).
    -c. Sensation of electrical shock and allodynia with partial damage to a nerve

          

  3. Cordotomy-cutting of a dorsal sensory nerve root

          

  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. Rhizotomy-cutting of a dorsal sensory nerve root

          

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