specific functions of the vestibular system

There are three main functions of the vestibular system. The first one is to provide a subjective sensation of movement in 3-dimensional space. For example, the hair cells of the utricle provide a sensation of head tilt based on the direction in which the cilia are bent by gravitational force. The second primary function of the vestibular sense is to maintain upright body posture or balance. A variety of reflexes of the limb musculature, are done by activation of the otolith organs and secmicircular canals. The third function is to control the muscles that move the eyes, so that in spite of the changes in head position which occur during normal activities, the eyes remain stabilized on a point.
