  1. Corticospinal (anterior)
    Ipsilateral, voluntary, discrete, skilled motion
  2. Corticospinal (lateral)
    Contralateral, voluntary, fine motor
  3. Damage to corticospinal (pyramidal tracts)
    • + babinski
    • decreased abdominal reflex
    • decreased fine and skilled motor
  4. Retiuclospinal
    • Facilitate/inhibit, voluntary and reflexic activity through alpha and gamma motor neurons
    • I
  5. Rubrospinal
    • 1. Contra, gross postural tone
    • 2. Facilitate flexors
    • 3. Inhibit extensors
    • Opp of vestibulospinal
  6. Tectospinal
    • Contra, postural and muscle tone associated with auditory/ visual stimuli
    • C
  7. Vestibulospinal
    • 1. Ipsi, gross postural adjustment due to head movement
    • 2. Facilitate extensors
    • 3. Inhibit flexors
    • Opp of rubrospinal
