The semicircular canals are the primary structure responsible for maintaining balance. They are filled with fluid and hair cells that detect changes in position and movement of the head, sending signals to the brainstem to adjust muscle activity in order to maintain balance. The cochlea is responsible for hearing and the middle ear helps to transmit sound waves to the cochlea. The circular canals are not a part of the human balance system.
