C) interneurons of central pattern generators.

Question

Quizplus · Accepted Answer

The corticospinal tract is responsible for controlling voluntary movements of the body. The interneurons of this tract synapse onto somatic or skeletal muscle efferents, which are responsible for movements of the arms, legs, and trunk. They do not synapse onto visceral efferents, which control smooth and cardiac muscles, or interneurons of central pattern generators, which are responsible for rhythmic movements like breathing and walking.
