Description:
This is a model of the right arm bones showing the humerus, radius, ulna, and wrist. Attached to the model are "muscles" involved in the functions of extension and flexion of the arm at the elbow and the flexion and extension of the wrist. The muscles are made from strips of pantyhose or red craft foam. "Tendons" made from rubber bands connect the muscles to the bones at the various attachment points (origin and insertion). Further testing of the muscle materials will be done.
