A sensory system is located in the structures of the inner ears which determines the orientation of the head or a condition of the bodily balance, maintained primarily by special receptors in the inner ear.

Sensory balance is the result of a number of body systems working together; specifically, in order to achieve balance the eyes (visual system), ears (vestibular system) and the body's sense of where it is in space (proprioception or the unconscious perception of movement and spatial orientation arising from stimuli within the body itself); all of which need to be intact and normally coordinated.
