spinal tracts

  1. Function of lateral spinothalamic tract
    Pain and temperature
  2. Function of Anterior Spinothalamic Tract
    Light touch, poorly localized
  3. Function of Posterior Spinocerebellar tract
    Movement and positioning BELOW C8
  4. Function of Anterior Spinocerebellar tract
    Movement and position sense
  5. Function of Corticospinal tract
    Voluntary movement
  6. Function of Tectospinal tract
    Visual following and eye centering reflexes
  7. Function of Rubrospinal Tract
    • Alternate route than corticospinal tract
    • Control flexor muscle tone in the limbs
