The model is wired for natural movement and features a removable skull with the calvaria cut.  Miniature springs hold the mandible in place to demonstrate TMJ problems.  Tiny screws hold arms and legs in position so you can bend the extremities in all directions. 

All the bones are molded individually except in the hands and feet.  Although the basic appearance and functional value of the skeleton is excellent, there is a possibility of construction anomalies, such as rough plastic.
