Question

function of round window​

Answer 1

Round Window

If you started at the oval window and travelled all the way through the fluid-filled tube in your cochlea, you'd eventually come to another membrane called the round window. The round window is important because the fluid is just water with different chemicals dissolved in it, and water is almost incompressible, which means you can't change its volume by exerting pressure on it. For pressure waves to travel through the fluid, then, the pressure needs to be relieved, and that's what the round window does. By vibrating, the round window membrane relieves the pressure created by the waves generated by the oval window. The oval window and the round window are a little like two sheets of cellophane at opposite ends of a fluid-filled tube -- when one of them vibrates, the pressure it creates will ultimately be relieved by the other.
