. The anatomy of the domestic animals . Veterinary anatomy. 148 SKELETON OF THE OX for the extensor tendons are shallow. The proximal end unites with the shaft at one to one and one-half years, and the distal at three and one-half to four years.

The obliquity of the joint surfaces produces lateral deviation of the lower part of the limb in flexion. The facets for the radial and intermediate carpals are narrower than in the horse and run obUquely dorso-laterally. The surface for the uhiar carpal is extensive and saddle-shaped; its lateral part is fm'nished by the ulna. The ulna is more fully developed than in the horse. The shaft is complete, three-sided, and strongly curved. It is fused with the radius in the adult, except at the two interosseous spaces mentioned above. Its proximal part contains a medullary cavity which extends somewhat into the proximal end. The olecranon is. Mc. Fig. 148.—Left Carpus and Adj.^cent Bones of Ox; Front \'iew.
