A hinge joint primarily connects three bones: the humerus, ulna, and radius in the elbow, or the femur, tibia, and patella in the knee. In the elbow, the humerus forms the upper arm bone, while the ulna and radius are the forearm bones that allow for bending and straightening. In the knee, the femur is the thigh bone, while the tibia is the shin bone and the patella is the kneecap, facilitating movement in a similar manner.
