Sorry if this is a dumb question but what is the difference between the anterior and the lateral corticospinal tracts? I vaguely remember being told that the LCS innervates distal body parts (eg hands) while the ACS innervates proximal body parts, is this right?

Thanks

Anterior doesnt cross the midline and controls ipsilateral trunk muscles (10% of the neurons of the corticospinal tracts). Lateral corticospinal tract (comprises 90% of neurons of the corticospinal tract) crosses the midline and innervate contralateral limbs
