The inner vestibule, or vestibule of the ear, is located in the inner ear and senses changes in the position of the head and is an important structure for maintaining balance. The vestibule is an important part of the inner ear and consists of the ellipsoid sac, the ball sac and the three semicircular canals. The vestibule is an important part of the inner ear, consisting of the oval capsule, the ball sac, and the three semicircular canals. It senses the angular acceleration and linear acceleration when the body rotates, and maintains the body’s balance according to the signals it receives, making it a very important body balance organ. When this organ is diseased, people may feel dizzy and have vertigo symptoms. The vestibule is only one part of the balance system. It is involved in the process of establishing and maintaining our sense of balance, along with the visual and proprioceptive systems. It collects information and integrates it with the central systems of the vestibular nuclei of the brainstem, the cerebral cortex, cerebellum, and the reticular formation, and then directs the human musculoskeletal and visual systems to maintain body balance at all times.
