The tract begins in the primary motor cortex, where the soma of pyramidal neurons are located within cortical layer V. Axons for these neurons travel in bundles through the internal capsule, cerebral peduncles, and ventral pons. The term pyramidal tracts refers to upper motor neurons that originate in the cerebral cortex and terminate in the spinal cord (corticospinal) or brainstem (corticobulbar). Nerves emerge in the cerebral cortex, pass down and may cross sides in the medulla oblongata, and travel as part of the spinal … Visa mer The pyramidal tracts include both the corticobulbar tract and the corticospinal tract.
