The microscopic structure of bone of the brow region was studied in adult human crania showing the vermiculate surface pattern, and in immature nonhuman primates with an areolar surface. Serial sections from different parts of each brow sampled regional comparability. The human brow regions are basically similar, and differ from those of the other primates. The elevations and depressions of vermiculate surfaces are lamellar bone, usually covered by layers featuring Sharpey's fibers. In contrast, the immature nonhuman primates do not have continuous brow surface layers. Passageways to the interior are closely spaced and separated by irregular projections. These findings indicate that fossil and modern human vermiculate surfaces are not structurally equivalent to areolar brow surfaces observed in some immature nonhuman primates. Reports describing fossil hominid brow regions as composed of 'fine cancellous bone' are probably erroneous and give misleading interpretations of their development and function.
对呈现蠕虫状表面模式的成年人类颅骨以及具有蜂窝状表面的未成熟非人类灵长类动物的眉区骨骼微观结构进行了研究。从每个眉区的不同部位获取连续切片,以确保区域可比性。人类眉区基本相似,与其他灵长类动物的眉区不同。蠕虫状表面的隆起和凹陷是板层骨,通常覆盖着含有夏佩氏纤维的层。相比之下,未成熟的非人类灵长类动物没有连续的眉表面层。通向内部的通道间距紧密,被不规则的突起隔开。这些发现表明,化石和现代人类的蠕虫状表面在结构上与在一些未成熟非人类灵长类动物中观察到的蜂窝状眉表面并不等同。将化石原始人类眉区描述为由“细松质骨”组成的报告可能是错误的,并且对其发育和功能给出了误导性的解释。
