The three ossicles in the middle ear are the malleus, incus, and stapes, which are crucial for transmitting sound vibrations from the eardrum to the inner ear. The malleus, also known as the hammer, is attached to the eardrum, the incus serves as a bridge between the malleus and stapes, and the stapes, the smallest bone in the body, connects to the oval window of the cochlea. This arrangement amplifies sound waves, facilitating hearing.
