How do you make a working model of an elbow joint?

To make a working model of an elbow joint, you'll need materials like a cardboard base, straws or wooden dowels to represent the bones (humerus and radius/ulna), and string or rubber bands to simulate the ligaments and tendons. Attach the straws or dowels at one end to allow for a hinge-like movement, mimicking the flexion and extension of the elbow. Use the string or rubber bands to create tension, ensuring the joint can bend and straighten realistically. Finally, decorate the model to illustrate the anatomy accurately.
