There are two 3dsMax versions. The new one with the V-Ray setup is the updated new one. The old MentalRay version (last two pictures) is also downloadable.
This ear is a stylized version of the inner ear. The propotions are modified for a better explanation.
This is not the full anatomy - these are just the main parts that are involved in the hearing process.
This product was modeled in 3Ds Max 2010 and rendered with V-Ray 2.10.01.

The UVs are just planar - texture size is enough for High Definition setup.
Hope you like it.
