Which bone connects the eardrum to the incus?

Explanation:
Understanding how the middle ear bones transmit sound begins with the circuit from the eardrum to the inner ear. The eardrum’s vibration is picked up by the malleus, the hammer-shaped bone that is attached directly to the eardrum. This bone passes the motion to the incus (the anvil), which then transfers it to the stapes (the stirrup). The stapes connects to the oval window of the inner ear, delivering the vibration into the fluids there. So, the bone that directly connects the eardrum to the next bone in the chain is the malleus, making it the correct choice. The incus sits between malleus and stapes, and the pinna is part of the outer ear, not the middle ear bone.
