Deluxe Eight-Part Ear

5 times life-size in unbreakable vinyl, our most detailed ear model provides more complete perspective of the middle and inner ear structures within the temporal bone.

All the skin has been peeled off the detachable auricle to expose its cartilaginous structure, muscles, auricular arteries and nerves, as well as the entrance to the auditory canal. Sections of the petrous and mastoid portions of the temporal bone can be lifted off to expose the middle and inner ear chambers. The tympanic ring with its see-through tympanic membrane and attached ossicles can also be lifted out.

The extractable labyrinth is dissectible into three portions. Half of it, consisting of the semicircular canals and vestibule, demonstrates the sense of balance. Transparent tubing with colored liquid represents two of the semicircular canals. An air bubble in each will move when tipped, demonstrating the canals? function in equilibrium. The other half of the labyrinth, upon removal, shows the vestibular and cochlear nerves, which join to form the auditory nerve. The cochlea itself separates into halves to reveal cochlear, vestibular and tympanic ducts and the branching of the cochlear nerve.

95 hand-numbered features are identified in the corresponding key. Overall dimensions: 17x11x8 inches (43x28x20 cm) overall.

Very good model September 26, 2014
Reviewer: Verified Buyer from El Paso, TX  
As a radiologist, I found this deluxe model of the ear to be lacking when it came to the anatomy that is important to my profession. Specifically, the aditus ad antrum, mastoid antrum, tegmentum tympani, pyramidal eminence, sinus tympani, scutum, vestibule, cochlear aqueduct, vestibular aqueduct, and mandibular condyle are either not present or not marked. Most of these, however, I corrected by adding my own small round colored stickers to the anatomy (or general location of the anatomy).     On the other hand, there are many items that are not clinically relevant. For instance, the ear anatomy is far too detailed.     To be fair, though, many of these items are better left as is, because to render them would make the model too delicate and easily breakable. Even so, the model would have been much better had the artist spent a day with a radiologist to find out what additional items should have been included.    FYI - Several of the anatomic names use British, as opposed to American, terminology.
