Incus

The incus, also known as the anvil, is one of the three small bones in the middle ear that help transmit sound from the outer ear to the inner ear. It connects to the malleus (hammer) and the stapes (stirrup), acting as a bridge to carry vibrations. When sound waves hit the eardrum, they cause the malleus to vibrate, which then passes these vibrations to the incus. The incus amplifies and transfers them to the stapes, ultimately sending signals to the brain for interpretation. These tiny bones are essential for our ability to hear clearly.
