The corticospinal tract is a white matter motor pathway starting at the cerebral cortex that terminates on lower motor neurons and interneurons in the spinal cord, controlling movements of the limbs and trunk.[1] There are more than one million neurons in the corticospinal tract, and they become myelinated usually in the first two years of life.
The corticospinal tract is one of the pyramidal tracts, the other being the corticobulbar tract.
