The ossicles are the three tiny bones of the middle ear located directly behind the tympanic membrane. These are the three tiny bones (smallest in the human body) in the middle ear: malleus (hammer), incus (anvil,) and stapes (stirrup) and their job is to further amplify the sound. These three bones form a connected chain in the middle ear. The malleus is embedded in the innermost layer of the tympanic membrane, and the stapes is connected to a membranous window of the inner ear, called the oval window. The ossicles translate mechanical vibrations received at the eardrum into the inner ear.
