Function and Bony Landmarks of the Ulna in Human Anatomy

The ulna is the medial forearm bone, longer than the radius, that stabilizes the forearm and articulates proximally with the humerus and radius via defined bony landmarks: the olecranon and coronoid process forming the trochlear notch that articulates with the humeral trochlea, and the radial notch that receives the head of the radius. This content belongs to osteology within human gross anatomy, describing structure-function relationships between bony landmarks and joint articulation/stability.
