The correct order in which a sound stimulates the structures in the ear is eardrum, ossicles, oval window, cochlea. This is because the sound waves first vibrate the eardrum, which then moves the ossicles (three tiny bones in the middle ear) that connect the eardrum to the oval window. The vibrations of the oval window create waves in the fluid-filled cochlea, where hair cells translate the waves into electrical signals that are sent to the brain.
