What is incus?

The incus is like a tiny helper inside your ear that helps you hear sounds more clearly.

Imagine you're listening to your favorite song through headphones. The sound waves go into your ear, and they need to be passed along so your brain can understand them. That’s where the incus comes in, it's one of three little bones (called ossicles) inside your middle ear that help send those sounds on their way.

How the incus works

Think of the incus like a seesaw in a playground. When sound waves hit your eardrum, they make it vibrate. The incus, along with its friends the malleus and stapes, moves back and forth like a seesaw, passing those vibrations to the cochlea (a snail-shaped part of your inner ear). This helps turn the sounds into signals your brain can understand.

Without the incus, hearing would be like trying to listen to music through a pillow, muffled and unclear!
