Question

Quizplus · Accepted Answer

The corticobulbar tract is responsible for the voluntary control of cranial nerves, which includes the muscles of the eye. The lateral rectus muscle is innervated by the sixth cranial nerve (abducens nerve), which is controlled by the corticobulbar tract. Therefore, an upper motor neuron supplying the lateral rectus muscle would be part of the corticobulbar tract.
