. The comparative anatomy of the domesticated animals. Veterinary anatomy. 766 THE NERVES. When it reaches the interstice of the triceps and anterior brachial, it crosses the limb above the outer face of the elbow, and divides into two series of terminal branches. The muscular branch enters beneath Fig. 351. the muscles on the anterior face of the fore- arm. The cutaneous bifurcates imme- diately: the smallest branch, passing in- wards, extends beyond the bend of the elbow, lies at the inner border of the median subcutaneous vein, and is distributed to the lower moiety of the fore-arm, the thumb, and internal border of the index digit. The largest lies at the outer side of the median subcutaneous vein; it sends a recurrent ramuscule to the bend of the elbow, and, at the elbow, detaches three filaments to the first, second, and third dorsal intermeta- carpal spaces; these filaments bifurcate at the dorsum of the digits to constitute the col- lateral dorsal nerves. The first metacarpal nerve anastomoses, by a fine transverse branch, with the ulnar ramuscule that constitutes the external dorsal collateral of the small digit. To resume : the radial of the Dog gives branches to the dorsal face of all the digits, except the external border of the first digit, or auricular] s. In the Cat, there are some differences. The internal branch of the radial sometimes lies with tlie external branch; it is placed at the inner border of the metacarpus, gives off a filament to the dorsal face of the thumb, and afterwards forms the internal dorsal collateral nerve of the index. The external branch leaves the anterior face of the carpus, and is situated at the origin of the third interosseous space, where it divides in<o three metacarpal branches; the external of these is very fine, and directed obliquely outwards, anastomosing with the dorsal branch of the ulnar, between the first and second digits. The median of the Dog is united to the A, Trunk of the median dividing into six ulna
