Question

Arrange the following in logical sequence.

Oval window, Tympanum, Cochlea, Auditory canal, Ear ossicles (path through which a vibration of sound is transferred in the human ear).

Answer 1

Sound waves enter the external auditory canal through pinna and cause the tympanic membrane to vibrate. Ear ossicles between the tympanic membrane and oval window, are associated with amplification of sound waves as passing from inner surface of tympanic membrane through oval window to basilar membrane in the cochlea. Vibrations of basilar membrane stimulate the hair cells of the organ of Corti. So, the correct sequence is "Auditory canal, Tympanum, Ear ossicles, Oval window, Cochlea".
