What type of movements does the corticobulbar tract control?

The corticobulbar tract is primarily responsible for controlling voluntary movements of the face and neck. It originates in the motor cortex of the brain and projects to various cranial nerve motor nuclei in the brainstem. This tract specifically facilitates the fine motor control required for facial expressions, speech production, and swallowing, as well as movements in the neck area. The connections made by the corticobulbar tract are crucial for the coordination and execution of these voluntary movements, allowing for intricate control over the facial and neck muscles. This function is why the answer focused on voluntary movements of the face and neck is the most accurate choice.
