One of these classification schemes separates the descending pathways into two groups based on the location of the descending axons in the white matter of spinal cord. Name the two groups of descending pathways according to this classification scheme. However, movement of one part of the body appears to by controlled almost solely by descending fibers in the corticospinal tract. Name this body part. Name and briefly describe the two systems of descending motor pathways according to the second classification scheme that was discussed in class.
