  • Basilar Membrane

  • Found in the organ of Corti, it is the cellular membrane in which the hair cells are embedded. The basilar membrane moves in response to pressure waves in the cochlea, initiating a chain of events that results in a nerve impulse traveling to the brain.

  • Benign Paroxysmal Positional Vertigo (BPPV)

  • A condition where certain head movements cause extreme dizziness. Benign means not life-threatening; paroxysmal means a brief burst; positional indicates the problem occurs with a certain body movement to a given position; and vertigo means a spinning sensation. BPPV is thought to be caused by loose particles or degenerative debris in the balance portion of the inner ear, which have migrated (moved) to an area in which they are not normally found. Certain body movements cause these particles to move, causing a perception of spinning dizziness.
