cortical motor areas can control alpha motor neurons and the brainstem (higher levels monitoring lower areas)
Tectum (roof of midbrain)
Vestibular spinal tract: 5 accelerometers in ears which land on alpha motor neurons which are set off by gravity. constantly sending a tonic signal to inform you of where you are
