Ear

The ear consists of internal, middle and external parts. The first two parts are concerned with the transference of sound waves from the exterior to the inner ear. The inner ear concerns with the balance and hearing.
Components of the ear:
1. the external ear consists of the auricle, the external auditory meatus and the tympanic membrane;
2. the middle ear components are the auditory tube and the tympanic cavity with auditory ossicles;
3. the inner ear consists of the cochlea (containing the organ of Corti) and the vestibular apparatus (containing the semicircular canals, the saccule and the utricle).
