Reflection
How many bones did your model need? How many muscles did it need? It needed 2 muscle and 1 bone.
- How were your pretend muscles similar to real muscles? Different? They were similar because they acted like a real elbow when relaxing and contracting our elbow joint.
- What changes occur to the real muscles in the human body to make them pull on bones? The Triceps relax and let the arm go down and the Biceps contract and pull the muscle upward.
- What would happen if the ligaments of the models were overstretched or torn? How would it affect the way the models could operate? If they were torn then the model would not be able to bend and the whole thing wouldn't work the way
