Corticobulbar Tract
The corticobulbar (or corticonuclear) tract is a white matter pathway connecting the cerebral cortex to the brainstem. The 'bulb' is an archaic term for the medulla oblongata; in modern clinical usage, it sometimes includes the pons as well. The word 'bulbar' therefore refers to the nerves and tracts connected to the medulla, and also by association to the muscles thus innervated, those of the tongue, pharynx and larynx.
Famous quotes containing the word tract:
“When the State wishes to endow an academy or university, it grants it a tract of forest land: one saw represents an academy, a gang, a university.”
—Henry David Thoreau (1817–1862)
