corticobulbar

 [kor″tĭ-ko-bul´ber]
pertaining to or connecting the cerebral cortex and the medulla oblongata or brainstem.

cor·ti·co·bul·bar fi·bers

term formerly used to describe projections of the motor and sensory cortices to nuclei of the rhombencephalon innervating the musculature of the face, tongue, and jaws and some fibers to rhombencephalic relay nuclei; replaced by bulbar corticonuclear fibers (to medulla), pontine corticonuclear fibers (to pons), and mesencephalic corticonuclear fibers (to midbrain). See these individual entries.
