Cortical bulbar system
In neuroanatomy, the corticobulbar (or corticonuclear) tract is a two-neuron white matter motor pathway connecting the motor cortex in the cerebral cortex to the medullary pyramids, which are part of the brainstem's medulla oblongata (also called "bulbar") region, and are primarily involved in carrying … See more The corticobulbar tract originates in the primary motor cortex of the frontal lobe, just superior to the lateral fissure and rostral to the central sulcus in the precentral gyrus (Brodmann area 4).
