Quizplus · Accepted Answer

The corticobulbar tracts are responsible for controlling the skeletal muscles of the face, head and neck, but not the muscles of the upper legs. Eye movements, certain superficial muscles of the back and neck, cranial, facial, pharyngeal, and laryngeal muscles, as well as intrinsic and extrinsic muscles of the tongue are all controlled by the corticobulbar tracts.
