Vestibular system Vestibular system Equilibrioception or sense of balance is one of the physiological senses. It allows humans and animals to walk etc. without falling. Some animals are better in this than humans, for example allowing a cat (as a quadruped using its inner ear and tail) to walk on a thin fence. All forms of equilibrioception can be described as the detection of acceleration. ...more on Wikipedia about "Equilibrioception"

The semicircular canals are three half-circular, interconnected tubes located inside each ear that are the equivalent of three gyroscopes located in three planes perpendicular (at right angles) to each other. ...more on Wikipedia about "Semicircular canal"
The statocyst is a balance organ present in some aquatic invertebrates ( Cnidarians, Ctenophores, Bilaterians). It consists of a sac-like structure containing a mineralised mass ( statolith) and numerous innervated sensory hairs ( setae). The statolith possesses inertia, causing the mass to move when accelerated. Deflection of seta by the statolith in response to gravity activates neurons, providing feedback to the animal on change in orientation and allowing balance to be maintained. ...more on Wikipedia about "Statocyst"
The vestibular system, or balance system, is the sensory system that provides the dominant input about our movement and orientation in space. Together with the cochlea, the auditory organ, it is situated in the vestibulum in the inner ear (Figure 1). As our movements consist of rotations and translations, the vestibular system comprises two components: ...more on Wikipedia about "Vestibular system"
The vestibulocochlear nerve is the eighth of twelve cranial nerves and also known as the auditory nerve. It is the nerve along which the sensory cells (the hair cells) of the inner ear transmit information to the brain. It consists of the cochlear nerve, carrying information about hearing, and the vestibular nerve, carrying information about balance. The auditory nerve is also known as the acoustic nerve. ...more on Wikipedia about "Vestibulocochlear nerve"
