SKELETONS CAN DO AMAZING THINGS!

IMPORTANT:
IB requires you to know the elbow, hip,and knee. Its not in the presentation but make sure you know it! Remember, HINGE JOINT. Elbow is most important to IB, and make sure you can compare it to the hip.

Also, the hip! BALL AND SOCKET JOINT. This also shows what happens to it when you get arthritis.



Also, the knee! also a HINGE JOINT.
