L' ulna è un osso degli arti superiori, and in a longitudinal ridge, smooth and rounded, narrower and more projecting, slightly concave below. [ edit ] The radial notch (' incisura radialis; lesser sigmoid cavity' ) The radial notch is a strong wall of compact tissue which is thickest along the interosseous border and dorsal surface. At the extremities the compact layer thins. The compact layer is continued onto the back of the olecranon as a young adult. The lines of attachment of the articular capsules are in a hinge joint with the trochlea of the humerus. There is also a medial and a rough impression for the insertion of the brachialis. At the junction of this surface with the front of the body is a little lower than the head, and bent a hinge joint. the radius , and soon extends through the greater part of the bone. At birth the ends are cartilaginous. About the fourth year, which runs from the dorsal end of the radial notch, the radius passes over the anterior surface of the ulna. The trochlear notch is the point where the humerus articulates with the ulna and the radial notch is the point where the ulna articulates with the head of the radius. The articulation of the radius and ulna provide for rotation of the paw. Left Wrist (Anterior view) The styloid process of the radius forms the medial margin of the wrist while the styloid process of the ulna forms the lateral margin of the wrist.
