The primary function of the vestibular system is to maintain balance and spatial orientation. This complex system, located in the inner ear, detects changes in head position and movement through fluid-filled canals and sensory hair cells. It processes this information and sends signals to the brain, allowing us to coordinate movements, maintain equilibrium, and execute postural adjustments. A well-functioning vestibular system is essential for activities such as walking, standing, and engaging in sports, enhancing our overall physical performance and safety.
