Two cial branch continues distal to the carpus and divides cutaneous branches supply the craniolateral skin over into two dorsal common digital nerves (II and III).1 the brachium and proximal antebrachium; a small Dorsal common digital nerve II supplies the abaxial sur- autonomous zone is present in the dog over the lateral face of digit III.1 Dorsal common nerve III furnishes aspect of the brachium.32 sensory supply to the dorsal axial surfaces of digits III In the horse, the radial nerve follows the caudal border and IV.1 The dorsum of the manus is supplied through of the brachial artery and then travels distally between the cutaneous innervation by radial nerve branches in the heads of the triceps muscle.

The success and handiness of our original Hoof Anatomy Pocket Guide, led us to create this expanded, in-depth guide to the equine distal limb. extension), axial rotation, and lateral bending.15,16 The The horse has 15 to 21 caudal vertebrae,1,4 of which horse and ox have a relatively rigid vertebral column only the most cranial have transverse processes. Equine Vet muscles. An official website of the United States government. The sacrum of the nal bending in a vertical plane (dorsoventral flexion and ox, like that of the horse, possesses dorsal foramina. Which statement is true regarding the slap test? It then courses with the femoral artery distally, probably have concurrent involvement of the sciatic providing general somatic afferents to the skin over the nerve.53,54 medial crus and, in the horse and ox, the dorsomedial The sciatic nerve emerges from the pelvis via the metatarsus and fetlock joint (Figure 2).48 In the dog, the major ischiatic foramen (horse and ox) or ischiatic notch sensory supply to the skin of the medial pelvic limb is (dog). The Forelimb of the Horse 24. b. inability to adduct the pelvic limb. Just proximal to the sti- three distinct divisions: a medial branch that supplies fle, the nerve splits into common peroneal and tibial digit III, a middle branch that supplies the axial por- nerve branches.55 Sensory branches, including the lateral tions of digits III and IV, and a lateral branch that cutaneous sural and distal caudal cutaneous sural nerves, innervates the abaxial surface of digit IV.3 As in the supply the skin of the lateral crus and caudal crus, horse, the deep peroneal nerve supplies the muscles of respectively.49 Sciatic nerve palsy results in hyperflexion the cranial crus and then runs in a groove in the dorsal at the tarsus with knuckling of the distal pelvic limb.35 metatarsus. species. 16. Levine discloses that he has of the atlas. Homologies or analogies are body parts that are similar. The forelimb skeleton consists of the thoracic or pectoral girdle and bones of the forelimb (see Figures 5-5 and 5-6). The size of forelimb bones varies a great deal, because of the greater variation in size for breeds of dogs. The forelimbs bear 60% of the dogs weight. The canine scapula is positioned close to the sagittal plane. In Pract CE tests or sign up for our annual CE program. In the horse, the branch of the peroneal nerve supplies the lateral digital tibial nerve can be blocked before its division, approxi- extensor and skin surrounding the lateral tarsus and mately 10 cm above the point of the hock, where it is metatarsus.48 The deep branch of the peroneal nerve of palpable between the tendon of the gastrocnemius and the horse dives between the lateral digital extensor and the deep flexor tendon.39,41,42 In the ox, the tibial nerve the long digital extensor, providing branches to these can be palpated as it courses along the cranial aspect of muscles as well as to the cranial tibial and peroneus ter- the calcanean tendon.1,3 The tibial nerve of the dog can tius muscles.56 As the deep branch continues distally, it be palpated and blocked in the caudal crus, where it becomes a purely sensory nerve that splits into medial runs parallel and cranial to the calcanean tendon. horse, cat, dog, ruminants well-developed clavicle = species w/ need for lateral movement of forelimb such as The functional anatomy of the forelimb and hind limb in the carnivore. requirements should consult their respective state JAVMA 167:298305, 1975. authorities regarding the applicability of this program. These two breeds of horse, at either end of the equine athletic spectrum, are ideally suited for comparative studies of equine hind limb anatomy and muscle architecture. 6. The second, divided into three basic motion segments based on joint third, and sometimes fourth caudal vertebrae of the ox morphology: atlanto-occipital, atlantoaxial, and C3 possess ventrally located hemal arches (which represent through C7.15,19 The atlanto-occipital joint permits a the fusion of hemal processes) along their ventromedial significant amount of dorsoventral flexion and extension aspects.4 (raising and lowering the head) as well as considerable September/October 2007 COMPENDIUM EQUINE, 4 Based on lever arm mechanics, it was expected that the forelimb of the prairie dog would show features appropriate to the production of relatively large forces and that of the fox squirrel to relatively great velocity.
