  1. With B12 deficiency, what regions of the spinal cord are affected and what clinical symptoms will be seen?
    Dorsal and Lateral Columns

    Dorsal Column System --> Loss of vibration / proprioception

    Lateral Columns --> Corticospinal Tracts causing weakness
  2. With Brown-Sequard Syndrome, what regions of the spinal cord are affected and what clinical symptoms will be seen?
    Cord Hemisection

    • Dorsal Column --> Ipsilateral loss of vibration and
    • proprioception
    • Corticospinal Tract --> Ipsilateral weakness
    • Anterolateral System --> Contralateral loss of pain and temperature
  3. With Friedreich's Ataxia, what regions of the spinal cord are affected and what clinical symptoms will be seen?
    • Dorsal Column --> Ipsilateral loss of vibration andproprioception
    • Corticospinal Tract --> Ipsilateral weakness
    • Spinocerebellar Tracts --> Tremor and ataxia
  4. With Polio, what regions of the spinal cord are affected and what clinical symptoms will be seen?
    Anterior Horn Cells

    Weakness
  5. With Syphilis, what regions of the spinal cord are affected and what clinical symptoms will be seen?
    Dorsal Columns
  6. With Syringomyelia, what regions of the spinal cord are affected and what clinical symptoms will be seen?
    Dilation of the central canal

    Anterolateral System at the Anterior White Commissure --> Bilateral pain + temp sensation at the level at +/-3 (band/cape-like)

    Anterior Horn Cells --> Bilateral weakness (trunkal flexors first; arms > legs)
  7. With Anterior Spinal Artery Infarction, what regions of the spinal cord are affected and what clinical symptoms will be seen?
    Anterior and Lateral Columns

    • Anterolateral System at the Anterior White Commissure --> Bilateral loss of pain + temp at that level +/-3 (band-like)
    • Anterolateral System --> Contralateral loss of pain + temp below that level
    • Corticospinal Tract --> Ipsilateral weakness at that level and below
    • Spinocerebellar Tracts --> Ipsilateral ataxia
  8. With Spinal Muscular Atrophy, what regions of the spinal cord are affected and what clinical symptoms will be seen?
    Anteiror Horn Cells
