The answer is "voluntary muscles."

Explanation:

Motor pathways are primarily responsible for controlling voluntary movements of the muscles. This type of pathway consist of the pyramidal system, a tract that supplies motor neurons of the brain stem or the spinal cord. This is responsible for the voluntary movements, as well as "posture" and "reflexes." This system controls fine motor skills such as picking up things, writing, blinking or playing an instrument.

The pathway also consist of the "extrapyramidal system," which is responsible for controlling larger groups of muscles. This enables the smooth movement when it comes to "locomotion."
