Inner ear vertigo, as the name implies, is caused by a disorder of the inner ear. The inner ear is a part of the human ear, which is divided into three parts: the outer ear, the middle ear and the inner ear. The inner ear is the most important, the outer ear serves as a sound collector and the middle ear serves as a sound transmitter. The inner ear serves the function of sound perception, and in addition to the function of sound perception, it also serves the function of balance. The inner ear is divided into three parts: the cochlea, the vestibule, and the semicircular canal. The cochlea is responsible for sound perception, the vestibule and the semicircular canal, which are responsible for balance. The inner ear plays a significant role in the ability of a normal person to maintain posture, walk, jump, and even perform difficult movements. The inner ear includes the vestibule and the semicircular canal. The vestibule has two very important parts called the ellipsoid and balloon sacs, which govern acceleration, the ellipsoid sac for horizontal acceleration and the balloon sac for vertical acceleration. In addition, there are 3 semicircular canals on each side and 6 semicircular canals on both sides. These 6 semicircular canals govern the 360° of the body, i.e., the entire three-dimensional space, a change of acceleration. As long as the human body is walking, or in any activity, the entire inner ear, including the ellipsoid capsule, balloon, and the three semicircular canals, are carrying out precise activities, providing the brain center with fine body positioning information. This is how the surrounding objects can be seen clearly, while maintaining a stable and normal posture, or posture, which is the function of the inner ear. The two major functions of the inner ear: 1. hearing, which the common people can understand, and when it comes to the vestibular function, it is mainly the function of maintaining balance, which is also a major function of the inner ear, relatively speaking without hearing, which we can understand more thoroughly; 2. the function of maintaining balance, which is very important for the human body’s posture judgment and for normal walking. If something goes wrong with the function of the vestibule of the inner ear and the semicircular canal, that is, the balance function, then what the patient feels is vertigo, which is called inner ear vertigo.
