Fig. 4.

Sus scrofa. Average peak strains from single element gauges across the internasal suture (solid lines) and intermaxillary sutures (dotted lines) and average peak principal strains/orientations from rosette gauges on the nasal bone during (A) mastication and (B) masseter muscle stimulation. Tensile strains are indicated by lines with arrows pointing in opposite directions and compressive strains by lines with converging arrows. Suture strains have open arrowheads and are 10 times their shown magnitude, as indicated by scale bar. Right and left unilateral stimulation strains are averaged for the intermaxillary and internasal suture (see Table 4). The asterisk indicates that the compressive arrowheads do not accurately reflect the small magnitude of the mean compressive strain.
