Corticobulbar Tracts EXPLAINED | Cranial Nerve Motor Function

The video tutorial by Kevin Tolkoff covers the corticobulbar tracts, explaining their role in synapsing with cranial nerves to control muscles of the head, face, and neck. It details the path of upper motor neurons through the brainstem, highlighting the midbrain, pons, and medulla. The tutorial also discusses the nuclei associated with cranial nerves and their function in muscle innervation. Additionally, it explains the concept of contralateral and bilateral control in facial muscles and the implications of strokes on these controls.
