Balance and the ability to remain upright is dependent upon three systems:
EYES>FEET>LEGG>NECK>INNER EAR>CEREBELLUM
All three of these systems give information to the brain about the position of the body in space. Generally people can keep their balance if two of the three systems are working, but they cannot cope with only one system working. This is why most people tend to become more unsteady as they get older, because they may have arthritis in their legs and their neck or poor eyesight.
The balance organ – labyrinth is made up of three semicircular canals and the vestibule, which are all filled with liquid. The semicircular canals sense rotational movement and the vestibule senses acceleration and deceleration.
