Explain how your biceps and triceps work to bend your arm at the elbow. Use the following words in your answer:
biceps & triceps
contract & relax
humerus & ulna/radius
It was hard for me because of restrictions for touching the elbow and talking to each other. another reason is that we had trouble coming up with and executing ideas.
It was fun because of all of the different things we had use and requirements we had to meet. Also it was fun to experiment with how to complete requirements.
Biceps and triceps work together to make your elbow move. Cartilage helps this process because without it our bones would rub together and it would be painful. Ligaments hold the humerus ulna and radius. The way the elbow actually is moved by is the contracting and relaxing of muscles and tendons.
