The production of defatted and durable skeletons is a not an easy task. The skeleton forms the scaffolding of the human body and of the roughly 200 bones in the human body, the Skull is the most difficult to teach and learn from to memorize. Instruction works best with a “Splitting Head Expanded Skull”, as has been the practice in anatomy education for over 100 years. The 22 individual bones of our Skulls are initially separated from each other and then reconnected with high-grade steel wire, leaving equal spaces between each the bones. This allows for a 3D view of each single skull bone and grants an interesting interior view.
