The incus, commonly known as the anvil, is one of the three small bones in the middle ear, collectively called the ossicles. It is situated between the malleus, or hammer, and the stapes, or stirrup. The incus plays a crucial role in the process of hearing by transmitting sound vibrations from the malleus to the stapes, which then sends these vibrations to the inner ear. The incus is shaped like an anvil, with a body and two arms. It is essential for amplifying sound waves, allowing us to perceive sounds more clearly. Any damage or dysfunction of the incus can lead to hearing loss, highlighting its importance in the auditory system.
