The medial vestibulospinal tract is a neural pathway that originates in the vestibular nuclei of the brainstem. It plays a crucial role in maintaining balance and coordinating head and neck movements by transmitting signals to the spinal cord. This tract primarily influences the muscles of the neck and upper back, helping to stabilize the head in response to changes in body position. This tract is part of the larger vestibulospinal system, which integrates sensory information from the inner ear to control posture and movement. By facilitating reflexive adjustments, the medial vestibulospinal tract ensures that the body remains upright and balanced during various activities.
