Anatomical definition of the corticospinal tract
The corticospinal tract is a large bundle of about 1 million fibers that arise from the cerebral cortex, converge in the subcortical white matter (corona radiata) and course through the posterior limb of the internal capsule, the cerebral peduncle of the midbrain, the ventral pons (basis pontis), the ventral surface of the medulla, decussate in the lower medulla (pyramidal decussation), and terminate in the spinal cord.
The corticospinal contains fibers from the motor and premotor cortices (Broadmann areas 4 and 6), the primary somatosensory cortex (Brodmann areas 3,1, and 2); and from the superior parietal lobule (areas 5 and 7).
