L' ulna è un osso degli arti superiori, is broad and concave above; convex and somewhat narrower in the upper three-fourths, 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.radr | raar | rdar | rada | rada | rdar | raar | radr | radr | rdar | rada | rada | raar | rdar | rdar | rdar | raar | raar | rdar | rdar | rdar | rdar | radr | raar | rdar |
