The vestibular system, in most
mammals, is the sensory system that
provides the leading contribution to
the sense of balance and spatial
orientation for the purpose of
coordinating movement with
balance - #WIKIPEDIA.
Here is an explanation:
Vestibular systemThevestibular system, in most mammals, is thesensory systemthat provides the leading contribution to thesense of balanceandspatial orientationfor the purpose of coordinatingmovementwithbalance.Together with thecochlea, a part of theauditory system, it constitutes thelabyrinth of the inner earin most mammals, situated in thevestibulumin theinner ear. As movements consist of rotations and translations, the vestibular system comprises two components: the semicircular canal system, which indicate rotational movements; and theotoliths, which indicate linear accelerations. The vestibular system sends signals primarily to the neural structures that control eye movements, and to the muscles that keep an animal upright. The projections to the former provide the anatomical basis of thevestibulo-ocular reflex, which is required for clear vision; and the projections to the muscles that control posture are necessary to keep an animal upright.The brain uses information from the vestibular system in the head and fromproprioceptionthroughout the body to understand the body'sdynamicsandkinematics(including its position and acceleration) from moment to moment.
The part of the mammalian ear responsible for maintenance of balance is the perilymph.
inner ear of mammals consists of the cochlea, which is involved with the sense of hearing, and the vestibule and three semicircular canals, which are involved with the sense of balance
