Question

Quizplus · Accepted Answer

The facial nuclei receive input from the primary motor cortex via the corticobulbar tract. The corticobulbar tract is responsible for the transmission of motor signals from the cortex to the cranial nerves which innervate the muscles of the face and head.

Option B is incorrect because the primary motor cortex sends motor signals to the spinal cord via the corticospinal tract, not the facial nuclei.

Option C is incorrect because the basal ganglia send motor signals to the spinal cord via the rubrospinal tract, not the facial nuclei.

Option D is incorrect because the substantia nigra sends motor signals to the spinal cord via the nigrostriatal pathway, not the facial nuclei.
