The vestibular system in the inner ear detects motion and orientation of the head to maintain balance. It contains semicircular canals that detect rotational head movement and otolith organs that detect linear acceleration. Signals from the vestibular system are integrated with other sensory inputs in the brainstem and cerebellum to coordinate eye movements and posture. Damage to the vestibular system can cause vertigo and loss of balance.
