The cochlea attaches with three rings of semicircular canals, arranged in three different spatial planes. The circulation of fluid in the semicircular canals helps the body to orientate the posture. Therefore, when the body changes in a certain direction, the stone particles moving in the semicircular canal in that plane will stimulate the vestibular system, send signals to the brain, and initiate the sensation of dizziness. . As a result, the body has a reflex to lie still, keeping the head position where it feels most secure. The pebbles do not move anymore, the feeling of dizziness will subside.
Besides, it is necessary to make a differential diagnosis with other diseases that also have symptoms of dizziness when central and peripheral vestibular organs are damaged such as inflammation, sclerosis, degeneration to ischemia, bleeding or trauma. The difference, however, is that the vertigo in these conditions has nothing to do with posture.
