Discover how the often-underestimated vestibule influences our posture and muscle tone. A quick connection between perception and movement essential for our balance!
Published on October 30, 2025
The vestibule not only stabilizes our gaze; it also controls postural tone through fast pathways connecting sensors to the spinal cord.
Otoliths → lateral vestibular nuclei → lateral vestibulospinal tract → extensor motor neurons. Inclination → almost reflexive contraction.
Head rotation → medial vestibular nucleus → medial vestibulospinal tract → cervical motor neurons. The vestibulo-colic reflex keeps the head stable.
Vestibular nuclei → reticular formation. Pons = increased tone, medulla = decreased tone. Adjusts postural stiffness according to the task.
The vestibule maintains a baseline level on extensors; without it, posture collapses despite intact cortical motor activity.
Hypofunction → widened gait, backward falls. Vestibular + optokinetic rehabilitation → -50% sway in 6 weeks.
The vestibule is the primary antigravity circuit; it regulates tone in real-time to maintain balance and precise movements.
