How many joint(s) form the elbow region?

The elbow region is formed by three distinct joints: the humeroulnar joint, the humeroradial joint, and the proximal radioulnar joint.

The humeroulnar joint is the primary hinge joint between the humerus and the ulna, allowing for flexion and extension. The humeroradial joint, which is a part of the larger elbow complex, contributes to the same movements while also allowing some rotation of the forearm. Lastly, the proximal radioulnar joint facilitates the rotational movements of the radius during pronation and supination of the forearm.

Thus, collectively, these three joints work together to provide a wide range of motion and functionality in the elbow region, making the answer three joints that form the elbow area.
