Vertigo

Sep 04, 2008 - Back HEALTH GUIDE REFERENCE FROM A.D.A.M Rotational head movements cause the fluid in the cupula of the semicircular canal to "bend" the hair cells. The hair cells, in turn, send a signal to your brain that you are experiencing "motion". Vertigo can occur when these hair cells are still sending signals of motion, even though you may be perfectly still, giving you the  "illusion of movement".  Review Date: 5/3/2006 Reviewed By: A.D.A.M. - 0 Comments
