The parts of the ears involved in balance are the semicircular canals. These are the curved structures above the cochlea in the inner ear in Figure above . Like the cochlea, the semicircular canals contain liquid and are lined with tiny hair cells. As the head changes position, the liquid moves. This causes the hair cells to bend. The bending of the hair cells triggers nerve impulses that travel to the cerebellum in the brain. The cerebellum uses the information to maintain balance.
Some people think Rock Music is just loud noise but Sam loves it. Sam liked going to Rock concert when he was younger. In his opinion the louder the better. Unfortunately over the years Sam's hearing has declined and he has trouble hearing the music he loves so much.
Is Sam's balance problem temerary or permanant?
