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. The canine scapula is the cutaneous innervation of the pelvic limb of male dogs. These act as 'ligaments' preventing dislocation of the shoulder. Description .

The dens of the ox is wider than that received research funding from of the horse; the dogs dens is relatively narrower Take CE tests Scott & White Health Center in and longer than that of large domestic species. Movement of the elbow joint is restricted to the sagittal plane. 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. 46. It houses just the deep digital flexor tendon in the dog. Evolution is nothing but a genetic change that occurs in a population over time. Similarities in the forelimbs of these two sciurids suggest that only minor modifications may have been required of the ancestral forelimb in order for descendent forms to operate successfully as climbers and diggers .

The uppermost bone in the foreleg is the scapula, or shoulder blade.
