The motor tracts carrying conscious demands/ motor commands consist of the:Anterior Corticospinal Tract:Contains about 10% of the fibers that travel in the corticospinal tract. Fibers that travel in this tract travel down to the spinal cord on the ipsilateral side of the brainstem from where they originated. It is involved in controlling proximal muscles such as those of the trunk. Lateral Corticospinal Tract:Main component of the corticospinal tract; contains about 90% of fibers that travel in this tract. Crossing over occurs in medullary pyramids and continue down to the spinal cord on the contralateral side of the brain stem. This tract is involved in controlling distal muscles (the limbs).Answer the following three questions with 1 of these three responses: Somatic motor commands, Visceral motor commands, or both somatic and visceral sensations 1.What kind of information does the anterior gray hornportion of the spinal cord receive
