Rigged skeleton arm - reference object for studying the functional anatomy of human arm

The skeleton arm presented here was created in order to help graphic artists who are using either digital or conventional creation methods, in studying the functionality of human arm. It was created by conventional quad dominant mesh editing. Its rig system includes constrains to simulate the restrictions posed by the anatomic features. Although the functionality is forward kinematics, the package also includes a version with an experimental IK rig that controls the upper and lower arm (it is a separate .blend file).
