Arm is made up of three long bones: our humerus in our upper arm and our ulna and radius in our lower arm. our upper and lower arms are connected at elbow by a hinge joint between humerus and ulna. our radius and ulna are linked at our elbow in a way that allows us to rotate our hand and forearm by more than 180 degrees. our ulna bone forms the point of our elbow.

What would happen if the joint between your arm and shoulder was not a ball and socket joint?

If the joint between your arm and shoulder was not a ball and socket joint, you could not be able to move your arm. Ball and socket joints allow you to move in most directions. Because of this, you can move your arm up, down, side to side, front and back, and around in a circle. The ball and socket joint is one of the four major kinds of movable joints. (The four major joints are ball and socket joints, gliding joints, hinge joints, and pivotal joints in case you didn't know.)
