We have chosen to use some terms consistently throughout the chapter, rather than use equally acceptable synonyms. The canine forelimb is known also as the thoracic limb and the pectoral limb, but we use the term forelimb. It has long served as one of the main evidences for evolution, due to the fact that it is very concrete, and does not require extensive technology. Comparative anatomy seeks to describe the structure of the bodies of organisms in terms of their homologous structures. 62. 2007;6(3):168-76. doi: 10.1080/14734220701332486.

The lack of clavicles allows for more movement at the shoulder joint and increases stride length. The structure of the forelimb of a bird is similar in structure to that of the forelimb of a mammal suggesting that both descended from a common ancestor. It connects the scapula and the two bones of the lower arm, the radius and ulna, and consists of three sections.

It is bounded medially and laterally by collateral ligaments between the humerus and radius, caudally by the olecranon ligament between the humerus and olecranon, and further enforced by the annular radial ligament.

A comparative study of the forelimbs of the semifossorial prairie dog, Cynomys gunnisoni , and the scansorial tree squirrel, Sciurus niger, was focused on the musculoskeletal design for digging in the former and climbing in the latter. 7. The nucleus pulposus of the ox is similar to that of tion and neurogenic atrophy of quadriceps femoris muscle in calves. The Scapula forms the basis of the shoulder region, providing points of attachment of extrinsic and intrinsic muscles. 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. There were no significant differences between the two species in the fatigability of the selected forelimb muscles, although the mean fatigue index was always higher (less fatigable muscle) in the prairie dog. After coursing in the pelvic canal alongside the The femoral nerve originates within the psoas major medial aspect of the ilium, it exits via the obturator fora- muscle and travels caudally in all three species.
