Simplified Anatomical Articulation Model

This simplified model of an articulation or joint, will help teachers show kids (3-12) how muscles, bones, tendons hinged by articulations work. It is inspired by the elbow joint and it is meant to show how the arm moves.

The model requires additional tubes, preferably cardboard, and some long balloons (the type to build balloon animals out of), and optionally tape and latex glove to make the hand. This makes it ideal for crafts project for kids to do.

It is customizable so it fits all tubes around the world.

The design includes a ring to tie the balloons to. I am opened to suggestions to make the model more anatomically accurate, or general improvements; like for example making a 3rd piece to help to tie the balloons on the opposite side of the tube of the joint.

This model may also be used for engineering, but probably requires some modifications.
