Elbow
The elbow joint bends when you flex your arm, bringing your hand closer to your shoulder. It also bends when you perform activities like throwing a ball or lifting weights.
The joint that allows your arm to bend is the elbow joint. It is a hinge joint formed between the humerus (upper arm bone) and the two bones of the forearm, the radius and ulna. This joint enables flexion and extension, allowing the arm to bend and straighten.
