Qtr 3 Advanced Neuroanatomy ALS

  1. Where are the first order neurons of the of the DCML found and what do they respond too?
    They are found in the DRG and they respond to mechano-receptors, vibration and fine touch
  2. At what level does the fasciculus cuneatus start?
    Above T6
  3. Where are the second order neurons found for the DCML?
    Nuclei gracilis and cuneatus in the medulla
  4. Where do the DCML fibers decussate?
    In the medulla (internal arcuate fibers)
  5. Where are the third order neurons of the DCML found?
    VPL nucleus of the thalamus
  6. Where are the first order neurons of the spinothalamic (ALS) tract found and what stimuli do they detect?
    They are found in the DRG and they respond to nociceptors, thermoreceptors, crude (light) touch
  7. Where are the second order neurons of the spinothalamic tract found?
    Lamina I and II
  8. Where do the second order neurons of the spinothalamic tract decussate?
    Anterior white commisure at level of DRG synapse
  9. What part of the thalamus are the third order neurons of the ALS found?
    VPL nucleus
  10. What type of motor lesion would have greater than 2+ reflex (hyperreflexia)
    Upper Motor Neuron Lesion
  11. What type of paralysis occurs with an upper motor neuron lesion?
    Spastic
  12. What type of paralysis occurs with a lower motor neuron lesion?
    Flaccid
  13. Where is the red nucleus found? What does it release? What disease is associated with its dysfunction?
    • Found in the Midbrain
    • Releases dopamine
    • Associated with parkinson's (lack of dopamine)
