The membrane vibrates three tiny bones, together called the (C) [Select ] . The third bone covers the oval window, which opens onto the scala vestibuli. Vibrations travel through fluid in the scala vestibuli, vibrating the (D) [ Select ] membrane, which vibrates fluid inside the (E) cochlear duct, which vibrates the (F) saccule . Finally, hair cells send action potentials that are interpreted as sound.
