Which bones are involved in the formation of the elbow joint?

The formation of the elbow joint primarily involves the humerus, radius, and ulna. The humerus is the bone of the upper arm that articulates with the two bones of the forearm, the radius and ulna. The elbow joint itself is a hinge joint, allowing for flexion and extension movements, and is formed at the junction between the distal end of the humerus and the proximal ends of the radius and ulna. This arrangement allows for the coordination and movement of the arm and forearm, essential for various functions such as lifting and throwing.
