In our previous developmental study on skin we reported that correlations existed between the collagen fibril diameter distribution, glycosaminoglycan content and composition, and mechanical role. In this work we present new but related electron microscope data on the ultrastructure of skins from flounder, marlin, cod, frog, toad, caiman, viper, pigeon, whale and opossum. It is shown that mammalian and avian body skins generally contain relatively sharp unimodal distributions of fibril diameter consistent with a "passive" mechanical role. In contrast most reptilian and fish skins have broad, right-skewed (or bimodal) distributions of fibril diameters compatible with the exotendinous attributes required of an "active" skin. A study of the changing form of the collagen fibril diameter distribution with depth in the dermis is also reported.
在我们之前关于皮肤的发育研究中，我们报告了胶原纤维直径分布、糖胺聚糖含量与组成以及力学作用之间存在相关性。在这项工作中，我们展示了关于比目鱼、马林鱼、鳕鱼、青蛙、蟾蜍、凯门鳄、蝰蛇、鸽子、鲸鱼和负鼠皮肤超微结构的新的但相关的电子显微镜数据。结果表明，哺乳动物和鸟类的体皮通常含有相对尖锐的单峰纤维直径分布，这与“被动”力学作用一致。相比之下，大多数爬行动物和鱼类的皮肤具有广泛的、右偏（或双峰）的纤维直径分布，这与“主动”皮肤所需的外腱属性相符。还报告了对真皮中胶原纤维直径分布随深度变化形式的研究。
