Our model needed 3 bones ( ulna raidous ,and humorous bones). The rest of the model only needed 2 muscles, 1 ligament and 2 tendons.
- How were your pretend muscles similar to real muscles? Different?
The muscles in our model where like real muscles because they both pulled to go up and down. The one difference was they where not as long as they should have been.
- What changes occur to the real muscles in the human body to make them pull on bones?
When the real muscle pulls it gets smaller and grows upwards but when it is relaxed it gets longer.
- What would happen if the ligaments of the models were overstretched or torn? How would it affect the way the models could operate?
If the ligaments where torn the ulna/raidois bones wouldn't be pulled as well and they would just be sitting there in the skin. so the entire model wouldn't work.
