Elbow joint, illustration 插畫檔

Illustration of the lateral anatomical structures of the elbow joint. The articulation between the distal humerus and the proximal ulna and radius is clearly demonstrated. The olecranon of the proximal ulna is prominently visible as a posterior bony prominence, while the radial head is located laterally and articulates with the capitulum of the humerus. The articular surfaces are covered by white articular cartilage, visually demonstrating the joint surface structures that function to provide cushioning and reduce friction
