Fig. 1.

Finite element model of a Macaca fascicularis cranium showing location of some of the regions from which strain (red) and displacement (green) data were collected. BDO, balancing side dorsal orbital region; DIO, dorsal interorbital; WDO, working side dorsal orbital; WPO, working side postorbital bar; WMZ, working side mid-zygomatic arch; WIO, working side infraorbital region; WIOA, working side inferolateral orbital angle. Not shown: balancing side mid-zygomatic arch, balancing side infraorbital, balancing side inferolateral orbital angle.
