The medial vestibulospinal tract primarily serves what purpose?

Explanation:
The main idea is that the medial vestibulospinal tract is all about keeping the head and neck steady. It originates in the brainstem’s medial vestibular nucleus and sends fibers down to the cervical spinal cord, mainly reaching neck muscles. This setup lets you quickly adjust neck muscle tone as you move, so your head stays upright and aligned with gravity. That stability is essential for keeping your gaze steady through the vestibulo-ocular reflex when your head tips or turns. It’s not primarily involved in starting gait, processing sounds, or innervating the eye muscles (those functions involve different pathways and cranial nerves).
