The middle ear consists of the tympanic membrane and the bony ossicles called the malleus, incus, and stapes. These three ossicles connect the tympanic membrane to the inner ear allowing for the transmission of sound waves.

What are the 3 ossicles and where are they located?

What kind of joints are found between the ossicles?

Incudomalleolar joint (more correctly called incudomallear joint) or articulatio incudomallearis is a small synovial joint between the malleus (hammer) and the incus (anvil). The joint’s function is to transfer vibrations between the ossicles in the middle ear, which is perceived as sound.
