Final answer:

The corticobulbar tract terminates in areas of the brain stem and is responsible for voluntary movements, but it does not extend to the spinal cord. The correct answer to the question is C. Spinal Cord. The correct option is C. Spinal Cord

Step-by-step explanation:

The Corticobulbar tract terminates in various areas of the brain stem but does not extend into the spinal cord. Therefore, among the options given, the correct answer is C. Spinal Cord. The corticobulbar tract is responsible for conscious or voluntary movements of skeletal muscles and projects from the cortex to the motor nucleus on the same side of the nervous system (ipsilateral). In contrast, the corticospinal tract crosses the midline of the brain stem or spinal cord (contralateral) and synapses with lower motor neurons in the ventral horn of the spinal cord, which then project to skeletal muscles. This descending pathway is crucial for voluntary motor control.

The correct option is C. Spinal Cord
