Brain Stem Pathways
• Lateral
– Rubrospinal tract: distal limb control; crude
(red nucleus)
• Medial
– Tectospinal tract: eye-head coordination
(superior colliculus)
– Reticulospinal tract: automatic postural
adjustments and movements (hip; shoulder)
(reticular formation)
– Vestibulospinal tract: balance (axial muscles);
automatic postural adjustments
(vestibular nuclei)
