It catches the sound waves to and transfers to bony ossicles pick these waves and transmit to the inner ear.
Structure of inner ear: The inner ear consists a complex system called vestibular apparatus located above the cochlea. Inner ear is a fluid filled chamber known as labyrinth. It is composed of outer bony labyrinth and inner membrane labyrinth. Labyrinth is also divided into cochlea and semi- circular canals. Each semi- circular canal lies in a different plane at right angles to each other. The base of the canals is swollen is called ampulla. An oval window in the cochlea receives sound waves from the stapes and sends auditory signals to the brain. Posture of the body is maintained by semi- circular canals.
