(Tympanic membrane, TM) and the inner ear. When airborne sound vibrates the TM, the ossicles perform an "impedance match" allowing sound energy to be transferred into the fluid filled inner ear, rather than just bouncing off.

The ossicles are situated in the middle ear and suspended by ligaments. They articulate with each other through synovial joints to form a chain across the length of the middle ear from the tympanic membrane (laterally) to the oval window (medially).
