The precise representation of the outer, middle and inner ear simplifies the explanation of clinical pictures and treatments. The 4-part ear model by HeineScientific portrays a 3-fold enlargement of the outer, middle and inner ear. In the middle ear, the eardrum with the auditory ossicles can be identified. The inner ear includes the 2-part labyrinth, complete with the cochlea and the vestibular organ. All four parts are removable.
This model portrays the following:
Middle and inner ear
Eardrum with hammer and anvil as well as 2-part labyrinth with stirrup bone
Cochlea and auditory and vestibular nerves (removable)
