The Scala Tympani is a fluid-filled cavity located within the cochlea of the inner ear. It is one of three main chambers in the cochlea, the others being the Scala Vestibuli and Scala Media. The Scala Tympani is filled with a fluid called perilymph, which plays a crucial role in the process of hearing by transmitting sound vibrations. Sound waves enter the cochlea through the oval window, causing the fluid in the Scala Tympani to move. This movement stimulates the hair cells in the organ of Corti, which convert the mechanical vibrations into electrical signals sent to the brain. Thus, the Scala Tympani is essential for the auditory process.
