Arrange the following in the order of reception and transmission of sound wave from the external auditory canal:

Cochlear nerve, ear drum, stapes, incus, malleus, cochlea.

The correct order is: Ear drum → Malleus → Incus → Stapes → Cochlea → Cochlear nerve

• Sound waves enter the ear, travel through the outer ear, enter the external auditory canal and strike the ear drum and make it vibrate.

• The central part of the ear drum is connected the malleus →found in the middle ear.) The malleus vibrates and transmits the vibrations to incus and stapes.

• From stapes it foes to the cochlea. Cochlea is fluid filled and contains hearing receptors.

• Cochlea has the organ of Corti which transmit the vibrations to the cochlear duct and finally to the cochlear nerve.
