线性尺寸和角取向的browridge,postorbital酒吧,和postorbital隔膜从一系列有代表性的灵长类动物和变量进行了比较,提出了几个非机械和生物力学/力学模型来解释的形式和功能的circumorbital区域。分析结果表明,脸的大小是灵长类动物的circumorbital形态变化的主要决定因素。前后browridge厚度与神经眶分离之间的灵长类动物,但不是在原猴。这种差异似乎与原猴亚目和原猴亚目的上面部和前颅窝的结构差异有关。小的支持被证明为前牙加载模型的browridge发展。中外侧眶后杆宽度和(在较小程度上)browridge高度与咀嚼过程中的面神经扭转和咀嚼肌大小的变化相关。这些分析进一步表明,由于眶周结构(特别是布罗里奇)位于离咀嚼器最远的地方,它们受咀嚼应力的影响最小。
Linear dimensions and angular orientations of the browridge, postorbital bar, and postorbital septum were obtained from a representative series of primates and compared with variables associated with several nonmechanical and biomechanical/mechanical models put forward to explain the form and function of the circumorbital region. Analyses of the results indicate that face size is the primary determinant of variation in primate circumorbital morphology. Anteroposterior browridge thickness is correlated with neural–orbital disjunction among anthropoid primates, but not among prosimians. This difference appears related to differences in the construction of the upper face and anterior cranial fossa between prosimians and anthropoids. Little support is demonstrated for the anterior dental loading model of browridge development. Mediolateral postorbital bar width and (to a lesser degree) browridge height are correlated with neurofacial torsion during mastication and variation in masticatory muscle size. These analyses further suggest that since circumorbital structures (especially the browridges) are located the farthest away from the chewing apparatus, they are least affected by masticatory stresses.
