The lateral corticospinal tracts decussate in the ( medulla, midbrain, pons ), then move down the spinal cord and synapse at the anterior horn on the ( contralateral, ipsilateral ) side to their origin (the primary motor cortex). Despite this, the tracts are considered to be ( ipsilateral, contralateral ) tracts due to the fact that they do not decussate at their level of entry and travel down the spinal cord on the same side as the structure they are innervating.
