Quizplus · Accepted Answer

Motor fibers are responsible for carrying impulses from the brain to muscles and glands, and these fibers mostly travel in the descending tracts of the spinal cord. Ascending tracts carry sensory information upward from the body to the brain, while medial, posterior, and lateral tracts carry a mix of sensory and motor fibers. Therefore, the best answer is C, descending tracts.
