The elbow is the region between the upper arm and the forearm that surrounds the elbow joint.

Understanding the Context

[1] The elbow includes prominent landmarks such as the olecranon, the cubital fossa (also called the chelidon, or the elbow pit), and the lateral and the medial epicondyles of the humerus. The elbow joint connects your upper and lower arms. It’s where your humerus meets your radius and ulna. The elbow is the joint that connects your upper arm to your forearm.

Key Insights

It helps you bend, straighten, and twist your arm so you can do everyday things like eating, lifting, or throwing. The elbow is the joint connecting the proper arm to the forearm. It is marked on the upper limb by the medial and lateral epicondyles, and the olecranon process. Structually, the joint is classed as a synovial joint, and functionally as a hinge joint. Attempts to force elbow movement past full extension of the arm (180 degrees) tear the joint’s protective capsule, producing elbow sprains, while chronic and repeated stressful motions, such as the rotation of the forearm in some sports, can cause pain from overuse of the joint (tennis elbow).
