E) visceral motor commands to smooth muscle

Quizplus · Accepted Answer

Structure labeled "4" represents the corticospinal tract, which carries motor commands from the cerebral cortex to skeletal muscles. Therefore, the type of information that travels along this pathway is motor commands to skeletal muscles.
