## Dizziness. Our balance is maintained, at least in part, by the endolymph fluid

Leave a tip for good service: https://paypal.me/jjthetutor Dizziness. Our balance is maintained, at least in part, by the endolymph fluid in the inner ear. Spinning displaces this fluid, causing dizziness. Suppose a dancer (or skater) is spinning at a very fast 3.0 revolutions per second about a vertical axis through the center of his head.…
