Draft:Corticospinal Tract; Corticospinal Tract
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. There are more than one million neurons in the corticospinal tract, and they become myelinated usually in the first two years of life.

LARGEST PART OF THE CORTICOSPINAL TRACT
Lateral cerebrospinal fasciculus; Crossed pyramidal tract; Tractus corticospinalis lateralis; Fasciculus cerebrospinalis lateralis; Lateral corticospinal tracts
The lateral corticospinal tract (also called the crossed pyramidal tract or lateral cerebrospinal fasciculus) is the largest part of the corticospinal tract. It extends throughout the entire length of the spinal cord, and on transverse section appears as an oval area in front of the posterior column and medial to the posterior spinocerebellar tract.
Anterolateral corticospinal tract
Anterolateral corticospinal tract is a subdivision of the corticospinal tract in the spinal cord. It is formed by approximately 2% of the corticospinal fibers that do not cross to the opposite side of the brainstem in the pyramidal decussation.
