The vestibular system is the sensory system that contributes to the sense of balance and spatial orientation for the purpose of coordinating movement with balance. Thus, we do not feel disorientated or have dizziness.
Together with the cochlea, the vestibular system constitutes the labyrinth of the inner ear and is situated in the vestibulum. Τhe vestibular system comprises of two components: the semicircular canal system, which indicate rotational movements; and the otoliths, which indicate linear accelerations.
Vestibular Rehabilitation and balance
The vestibular system sends signals primarily to the neural structures that control eye movements, and to the muscles that keep us upright. The projections to the former provide the anatomical basis of the vestibulo-ocular reflex, which is required for clear vision; and the projections to the muscles that control posture in order to keep us upright.
