The dorsal, volar, and interos- seous carpal ligaments vary with the number of carpal bones present in the different species. In the dog there are six dorsal and six volar ligaments. The inter- osseous ligaments are not inter- ordinal. The accessory carpal bone is attached by ligaments to the ulna, the radio-intermediate, and the third, fourth, and fifth metacarpal bones. The distal carpal bones are attached to the metacarpal bones by dorsal and volar ligaments. INTERMETACARPAL JOINTS In the ox the small (fifth) meta- carpal bone articulates with the large metacarpal, but not with the carpus. The joint cavity is connected with that of the carpo-metacarpal sac. The proximal end of the small meta- carpal bone is attached by a ligament to the fourth carpal, and another band extends from its distal part to the side of the large metacarpal. There is also an interosseous liga- ment, which is permanent and allows a small amount of movement. The chief metacarpal bones of the pig, and the second to the fifth of the dog, articulate with each other at their proximal ends, and are con- nected by interosseous ligaments, which do not, however, unite them closely, as in the horse. There are feeble dorsal and volar ligaments (Ligg. basium) which unite the proximal ends of the metacarpal bones in the dog. METACARPO-PHALANGEAL JOINTS Ox.—There are two joints, one for each digit. The volar parts of the two joint capsules communicate. The two interdigital collateral liga- ments (Ligg. collateralia interdigi- A strong oblique ligament connects the.
