Ossicles
Another name for eardrum, absorbs sound waves and begins to vibrate.
The ossicles are the three small bones located in the middle ear of mammals. They are collectively known as the malleus (hammer), incus (anvil), and stapes (stirrup), and together they form a chain that transmits sound waves from the outer ear to the inner ear.
The malleus is the largest of the ossicles and is attached to the eardrum. Its shape resembles that of a hammer, hence its name. The incus is the middle bone and sits between the malleus and the stapes. Its shape is similar to that of an anvil, which is how it got its name. The stapes is the smallest bone in the human body and its shape resembles a stirrup, hence its name. It is connected to the oval window, which separates the middle ear from the inner ear.
The ossicles are incredibly important for maintaining and interpreting sound. They work by receiving vibrations from the eardrum and amplifying and transmitting those vibrations to the inner ear, where they are then interpreted as sound by the brain. The unique shape and composition of each bone allows for this process to occur efficiently and accurately, making the ossicles an essential part of the hearing process.
Various disorders such as ear infections, genetic disorders, and injury can damage the ossicles, resulting in hearing loss. Surgery can be performed to repair or replace the damaged ossicles, allowing for the restoration of hearing.
