Explanation / Answer

Ans 12 a) Auditory canal , ear drum , hammer , anvil , stirrup , cochlea

The auditory canal extends from the pinna to eardrums that carry the sound vibration. The three ear ossicles of the ear convert these sound vibrations into mechanical vibrations as they strike to tympanic membrane. The vibrations are then carried to the internal ear that has cochlea and semicircular canals.
