MICROANATOMY

Detailed explanation-1: -The lateral corticospinal tracts are located laterally and slightly posteriorly. Within the column, arm function is located medially, truncate function in the middle, and leg function most laterally. This controls ipsilateral motor function. The spinothalamic tracts are anterior and lateral.

Detailed explanation-2: -There are two divisions of the corticospinal tract, the lateral corticospinal tract and the anterior corticospinal tract. The lateral corticospinal tract neurons cross the midline at the level of the medulla oblongata, and controls the limbs and digits.
