Figure 8 in Hanging on and digging deep: comparative forelimb myology of the koala (Phascolarctos cinereus) and common wombat (Vombatus ursinus)

Figure 8. Architectural parameters of muscle groups crossing the shoulder, elbow, and wrist in the koala (K) and the common wombat (W). The less y axis relates to stacked bars and shows (A) summed PCSA and (B) mean fascicle length (normalized by body mass). The right y axis relates to circle (koala) and square (wombat) points, and shows the ratio between these PCSA and FL values for each antagonistic muscle group, as a measure of relative emphasis placed by these species on opposing actions at each of the forelimb joints. Muscles assigned to each functional group are detailed in Table 5.
