Detailed explanation-2: -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-3: -In an adult human, 3 bones( malleus, incus, stapes) are present as ear ossicles.

Detailed explanation-4: -Middle ear There are three tiny bones in this area-the malleus, incus and stapes. (Healthcare providers refer to these three bones as the ossicles.) They transfer sound vibrations from your eardrum to your inner ear. Your middle ears also house the eustachian tubes, which help equalize the air pressure in your ears.

Detailed explanation-5: -Triple bone structure arose independently in platypus and humans. Listen up: mammals seem to have evolved the delicate bone structure of the middle ear at least twice. The surprising discovery comes from a fossil, found off the southern coast of Australia, that belongs to an ancestor of the platypus.
