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 Humerus is the long bone of the arm, articulating with the scapula to form the shoulder and the radius and ulna to form the elbow.

Twelve matured (6 BBGs and 6 dogs) male animals were sacrificed ethically to. The shoulder joint links the humerus and the scapula at the glenoid cavity, which is much smaller than the head of the humerus. 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.

The number of metacarpals varies widely among species, as the demand for their function changes: plantigrade, or flat-footed, animals requiring the full complement of five metacarpal bones; the number is reduced in the upright stature of digitigrade animals such as the dog and cat, and shows the extreme in unguligrades like the horse, which depends entirely on the third metacarpal bone for its stature. It innervates the supraspinatus and infraspinatus tory function in horses with suspected cervical spinal cord damage. Specific attention is paid to special reflexes of the horse.
