Except where otherwise noted content is available under. J Anat. The natural bones are affixed to a square wooden base (11-1/4 x 11-1/4") with a steel support rod. The medial palmar nerve then divides branches from the ulnar nerve proximal to the elbow to into a medial palmar digital nerve and a dorsal branch. Am J Vet Res 51:264267, 1990.

The elbow is a compound joint including: While in the human the radius and ulna are separated by an interosseus space and articulate only at their extremities, allowing for significant capability of supination and pronation, these movements are much more limited in domestic animals due to the gradual fusing of the two bones.

Contrary to expectation, in the few cases in which significant (P less than .05) differences were found, the forces, lever arms, and torques (force times its lever arm) were greater in the smaller fox squirrel. There are no true ligaments in the shoulder joint.

Start studying comparative anatomy of forelimb. The shoulder joint links the humerus and the scapula at the glenoid cavity, which is much smaller than the head of the humerus.

The metacarpal joint is defined by the presence of palmar sesamoids, which allow the flexor tendons to pass over the sharp change in angle presented by the joint. These muscle are responsible for joining the forelimb to the trunk, forming a synsarcosis rather than a conventional joint.
