Corticospinal tract drawing
WebThe 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. WebDec 1, 2011 · The CP is a compact area into which many descending corticofugal tracts converge and pass through. 1 ⇓ ⇓ –4 Due to its anatomic characteristics, occurrence of a brain injury at the CP could result in severe neurologic deficits. 5,6 Therefore, detailed clarification of the anatomy of the CP would be important for clinical neuroscience.
