Function of Motor and Sensory Pathways

  1. -paresis
    Weakness
  2. -plegia
    No movement
  3. Is weakness associated with injury to the upper motor neuron or lower motor neuron?
    Can be with both
  4. Is atrophy associated with injury to the upper motor neuron or lower motor neuron?
    Lower motor neuron
  5. Are fasciculations associated with injury to the upper motor neuron or lower motor neuron?
    • Lower motor neuron
    • Fasciculations = abnormal muscle twitches
  6. How are reflexes affected in upper motor neuron lesions?
    Increased
  7. How are reflexes affected in lower motor neuron lesions?
    Decreased
  8. How is tone affected in upper motor neuron lesions?
    Increased
  9. How is tone affected in lower motor neuron lesions?
    Decreased
  10. What is special about facial innervation?
    • Upper face (forehead) innervated by both sides of brain
    • Lower face innervated by opposite side of brain
  11. What symptoms would you see in a lesion in the following places? 
    Image Upload 2
    Bilateral arm and leg weakness or paralysis
  12. What symptoms would you see in a lesion in the following places? 
    Image Upload 4
    Unilateral face, arm, and leg weakness or paralysis
  13. What symptoms would you see in a lesion in the following places?
    Image Upload 6
    Unilateral arm and leg weakness or paralysis
  14. What symptoms would you see in a lesion in the following places? 
    Image Upload 8

  18. What symptoms would you see in a lesion in the following places? 
    Image Upload 16
    Unilateral facial weakness or paralysis (lower motor neuron type)
  19. What symptoms would you see in a lesion in the following places?
    Image Upload 18
    Unilateral facial weakness or paralysis (upper motor neuron type)
  20. What symptoms would you see in a lesion in the following places?
    Image Upload 20
    Bilateral leg weakness or paralysis
  21. Bilateral arm and leg weakness or paralysis possible sites of lesion
    • Medial aspect of cerebral cortex
    • Medulla
    • Cervical cord
    • Peripheral nerve
  22. Unilateral face, arm, and leg weakness or paralysis possible sites of lesion
    • Cerebral cortex
    • Internal capsule
    • Midbrain
  23. Unilateral arm and leg weakness or paralysis possible sites of lesion
    • Medial aspect of cerebral cortex
    • Medulla
    • Cervical cord
  24. Unilateral face and arm weakness or paralysis possible sites of lesion
    Lateral cerebral cortex
  25. Bilateral arm weakness or paralysis possible sites of lesion
    Cervical cord
  26. Unilateral arm weakness or paralysis possible sites of lesion
    • Lateral cerebral cortex
    • Peripheral nerve
  27. Unilateral leg weakness or paralysis possible sites of lesion
    • Medial aspect of cerebral cortex
    • Anywhere below cervical cord on same side of weakness
  28. Unilateral facial weakness or paralysis (all face) possible sites of lesion
    Lower motor neuron
  29. Unilateral facial weakness or paralysis (lower half of face) possible sites of lesion
    Upper motor neuron
  30. Bilateral leg weakness or paralysis possible sites of lesion
    • Medial cerebral cortex
    • Anywhere below cervical cord
