ANATOMY

Detailed explanation-1: -The middle ear contains three tiny bones: Hammer (malleus)-attached to the eardrum. Anvil (incus)-in the middle of the chain of bones. Stirrup (stapes)-attached to the membrane-covered opening that connects the middle ear with the inner ear (oval window)

Detailed explanation-2: -Hammer, anvil, and stirrup are the three bones that transmit sound. The center part of the eardrum is connected to the hammer. As the hammer vibrates, it transmits the sound to the other two bones, i.e. to the anvil and stirrup. These bones amplify the sound waves and all this takes place in the middle ear.

Detailed explanation-3: -The malleus, or hammer, is a hammer-shaped small bone or ossicle of the middle ear. It connects with the incus, and is attached to the inner surface of the eardrum. The word is Latin for ‘hammer’ or ‘mallet’. It transmits the sound vibrations from the eardrum to the incus (anvil).

Detailed explanation-4: -…the malleus, or hammer, the incus, or anvil, and the stapes, or stirrup. Together they form a short chain that crosses the middle ear and transmits vibrations caused by sound waves from the eardrum membrane to the liquid of the inner ear.

Detailed explanation-5: -Having three ossicles in the middle ear is one of the defining features of mammals. All reptiles and birds have only one middle ear ossicle, the stapes or columella.
