When the eardrum vibrates, it moves a set of bones called ____
A
ossicles
B
muscles
C
blood vessels
Explanation: 

Detailed explanation-1: -The vibrations from the eardrum set the ossicles into motion. The ossicles are actually tiny bones-the smallest in the human body. The three bones are named after their shapes: the malleus (hammer), incus (anvil) and stapes (stirrup). The ossicles further amplify the sound.

Detailed explanation-2: -The ossicles are, in order from the eardrum to the inner ear (from superficial to deep): the malleus, incus, and stapes, terms that in Latin are translated as “the hammer, anvil, and stirrup".

Detailed explanation-3: -Inside of the middle ear are the smallest bones in the body–the auditory ossicles, or ear bones. By definition, these three bones are named after their shape: malleus (“hammer”), incus (anvil), and stapes (stirrup).

Detailed explanation-4: -The eardrum vibrates from the incoming sound waves and sends these vibrations to three tiny bones in the middle ear. These bones are called the malleus, incus, and stapes.

Detailed explanation-5: -The eardrum is connected to the malleus, one of three small bones of the middle ear. Also called the hammer, it transmits sound vibrations to the incus, which passes them to the stapes.
