The fluid in the cochlea moves in response to vibrations from the oval window. 25,000 nerve endings are set in motion as the fluid moves.
Mechanical vibrations of the stapes footplate at the oval window generate pressure waves in the perilymph of the cochlea's scala vestibuli. These waves travel around the cochlea's tip, through the helicotrema, and into the scala tympani before dissipating as they hit the round window. Sound-induced pressure changes in the cochlea travel down the fluid-filled tympanic and vestibular canals, which are filled with a fluid called perilymph. The membranous oval window functions similarly to a piston in a hydraulic system, pushing and pulling on the enclosed fluid.
