Question

Quizplus · Accepted Answer

The correct sequence for the vibration of structures when a sound wave enters the ear is: Tympanic membrane (5), Auditory ossicles (1), Oval window (3), Perilymph (4), and Endolymph (2). This sequence follows the path of sound from the outer ear through the middle ear, where it vibrates the tympanic membrane and ossicles, to the inner ear, where it affects the oval window and then moves through the fluid-filled cochlea (perilymph followed by endolymph).
