Those involved (brachiocephalic m., biceps brachii, supraspinatus, and ascending pectorals) have other, more primary roles. Homologies or analogies are body parts that are similar. 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 .

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. At Cambridge University, it has for some time been given the name omothoracic junction, but this term has not entered common usage. It is held in place by a synsarcosis of muscles and does not form a conventional articulation with the trunk.
