To assist communication among human rehabilitation and veterinary colleagues, some anatomic terms used for dogs appear in regular print with the analogous terminology for humans in parentheses following the canine term. Joint motions are named, most commonly, by movement of the distal bone relative to the proximal bone. For example, cranial movement of the tibia on a stable femur is named stifle joint extension. (From Evans HE: Millers anatomy of the dog, ed 4, Philadelphia, 2013, WB Saunders.) Tarsus or tarsals (hock area) Sesamoid bones or cartilages Joint motion within a plane usually occurs around an axis of rotation, which may be centered within the joint space or within the bone comprising the joint. Hindlimb The canine distal radius has distinct facets for articulation with carpal bones, providing stability in weight bearing. WebEquine (one-toed/odd-toed ungulate) and horse are used interchangeably in this content. 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. Synchondrosis: Costochondralribs with cartilage Types of joints are listed in Box 5-2. The massive cervical extensor muscle activity requires relatively large and strong cervical vertebrae to support the muscle mass. To assist communication among human rehabilitation and veterinary colleagues, some anatomic terms used for dogs appear in regular print with the analogous terminology for humans in parentheses following the canine term. In the cranial lumbar spine, cranial and caudal articular surfaces are oriented between the transverse and sagittal planes, which facilitate lumbar spine flexion and extension. The hindlimbs bear 40% of the dogs weight. Most joints allow motion in more than one plane. Caudal or coccygeal: Cd1-Cd20; some dogs have more or fewer Syndesmosis: Middle radioulnar The consistent size in dogs reflects the relatively equivalent cranial-to-caudal compressive loading. Figure 5-8 Skeleton of the lateral hindlimb of the dog. Some joint motions are planar or gliding motions and do not occur around an axis of rotation. The ribs limit overall thoracic spine motion and protect internal organs. Ox: Ulna runs the full length of the radius. The dorsal plane divides the dog into ventral and dorsal portions. Metatarsal pad: Largest pad plantar to the MTP joints; triangular in shape Ox: Ulna runs the full length of the radius. There is a distinctive groove in the lateral malleolus, the sulcus malleolaris lateralis, through which course the tendons of the lateral digital extensor and peroneus brevis muscles. Trunk

Dogs have much more limitation in motion in the dorsal and transverse planes. One sesamoid bone in the tendon of the abductor pollicis longus

The axis has a dens, which projects cranially to allow pivotal motion between the atlas and axis.

The restricted joint motions and areas resulting from these joint alignments include atlantoaxial motion other than rotation, the cervical (C) 7-thoracic (T) 1 junction, the caudal thoracic region, and the sacrum. Flexion may also be referenced to limb motions involving closing angles during the swing phase of gait. 4.1 Carpal Joint; 5 Muscles of the Forelimb. T,t tibia or shin. Ungual process: Extension of the distal phalanx into the nail

The first metacarpal is short and nonfunctional. Pads on the paws or digital pads: Weight-bearing pads Axes of Rotation In vertebrae caudal to Cd6 and in relatively the same position as the hemal arches are the paired hemal processes, which extend from Cd7-Cd17 or Cd18. This deviation allows the hindpaws to pass lateral to the forepaws when dogs gallop.4 The calcaneus is large and serves as the insertion of the common calcaneal tendon. Canine intervertebral disks likewise change little in size from the cervical through the lumbar vertebrae. P,p pelvis. F,f femur or thigh bone. Saddle plane: First carpal with MC I The bones of the dog skeleton and limbs are illustrated in Figures 5-2, 5-3, and 5-4. Transverse axis: Sagittal plane motion occurs around an axis of rotation that is directed mediolaterally. 999 cigarettes product of mr same / redassedbaboon hacked games Extension is motion in the sagittal plane in the direction opposite to that of flexion motion. Like dogs, each horse is unique an individual with its own personality. Tarsal IV is large and articulates with the calcaneus and metatarsal bones, spanning this entire region. Each horse needs a confident and fair handler, one that can be assertive without being overly harsh and can guide and direct the horse into doing what is needed of it.

WebMany representative terrestrial vertebrates possess a distal cushion on the under-surface of the foot. Limb motion is usually described by motion of the joint rather than a body segment. Physiologic motion in joints with opposing concave and convex articular surfaces involves both roll and glide. At the talocrural joint, two convex ridges of the trochlea of the talus articulate with two reciprocal concave grooves of the cochlea of the tibia. P,p pelvis. The canine hindlimb is known also as the pelvic limb or rear limb, but we use the term hindlimb. Dogs have many sesamoid bones that are embedded in tendons or near them. WebComparative Anatomy of the Horse, Ox, and Dog CE 285 digit while supporting the limb appropriately at the level blocked at two sites: deep at the level of the base of the of the elbow.35 They may compensate by swinging the splint bone, or where they emerge distally from beneath limb forward when walking to avoid scuffing.36 the distal ends of the Dogs have many sesamoid bones that are embedded in tendons where there are significant compressive and tensile forces produced during muscle contractions. Digital pads or pads on the hindpawsweight-bearing pads Structures of the Proximal Forelimb and Shoulder Scapula The ox possesses a small tuber scapular with a acromion present It has extensive scapular cartilage Humerus The humerus is almost the same conformation as that of the dog. The third is the smallest, is located in the proximal attachment of the popliteus muscle, and articulates with the lateral tibial condyle. Talocalcaneocentral and calcaneoquartal joints combined 1.1 Scapula; 1.2 Clavicle; 1.3 Humerus; 1.4 Radius; 1.5 Ulna; 2 Joints of the Proximal Forelimb. The orientation of the grooves and ridges deviates laterally approximately 25 degrees from the sagittal plane. P,p pelvis. At the talocrural joint, two convex ridges of the trochlea of the talus articulate with two reciprocal concave grooves of the cochlea of the tibia. At T10, the size of the body begins to increase and the length of spinous process decreases. Part synovial and part fibrous: Sacroiliac Compressive or approximation accessory motions are compressive or pushing-together movements between bones. The horse possesses a centralized digital pad known as the frog, which is located at the distal aspect of the foot and surrounded by the hoof. A supracondylar foramen is present in the humerus for the passage of the brachial artery and median nerve (see Figs 10.29 and 10.30), although a supratrochlear foramen present in the humerus of the dog is absent in the cat. The transverse plane divides the body into cranial and caudal portions. The dog's paw contains a number of visco-elastic pads oriented along the middle and distal foot. There is a distinctive groove in the lateral malleolus, the sulcus malleolaris lateralis, through which course the tendons of the lateral digital extensor and peroneus brevis muscles. Pelvic girdle: Right and left hip bones and sacrum The canine sacrum is relatively narrow and is linked to the pelvis with sacroiliac joints (see Figure 5-14). The shape of articular surfaces of bones helps define the motions available for a joint. The carpus normally has greater than 180 degrees of extension. Canine spinous processes are relatively long. Between cranial and caudal articular surfaces R,r radius or lower arm. In normal stance, as shown in Figure 5-2, a dogs spine is flexed at the atlantooccipital and atlantoaxial joints, straight (neither flexed nor extended) in the remainder of the cervical spine, extended at the cervicothoracic junction, slightly lordotic in the thoracic spine, and flexed or normally kyphotic in the lumbar spine.
