The semicircular canals, saccule, and utricle are the parts located within the inner ear that are responsible for monitoring and maintaining balance. Information collected from the inner ear is sent to the brain stem and cerebellum to allow the body to be aware of its position and adjust as needed.
The inner ear contains three semicircular canals that are able to monitor changes in movement of the body. Hair cells located on the semicircular canals have the ability to sense movement of the head.
If abnormal signals are received from the inner ear, the body attempts to adjust. This is done by moving the arms and legs, as well as the posture of the spine.
