Medial vestibular pathway describes projections to motor neurons in the ventral horn of the cervical spinal cord.

• A. Thoracic
• B. Lumbar
• C. Cervical
• D. Sacral

Answer: (C)

The medial vestibulospinal pathway is specialized for stabilizing head position by acting on neck muscles, so its projections target motor neurons in the cervical spinal cord. Originating from the medial vestibular nucleus, it descends to the spinal cord and reaches the ventral horn where it can influence neurons controlling neck muscles. This cervical focus aligns with vestibulo-collic reflexes that help keep the head steady during movement. The thoracic, lumbar, and sacral levels are not the primary targets of this medial tract; other vestibulospinal or spinal pathways handle those regions and limb trunk control.
