Abstract：
One crucial component of the optical system is the ciliary body (CB). This body secretes the aqueous humour, which is essential to maintain the internal eye pressure as well as the clearness of the lens and cornea. The histological study was designed to provide the morphological differences of CB and iris in the anterior eye chambers of the following vertebrate classes: fish (grass carp), amphibians (Arabian toad), reptiles (semiaquatic turtle, fan-footed gecko, ocellated skink, Egyptian spiny-tailed lizard, Arabian horned viper), birds (common pigeon, common quail, common kestrel), and mammals (BALB/c mouse, rabbit, golden hamster, desert hedgehog, lesser Egyptian jerboa, Egyptian fruit bat). The results showed distinct morphological appearances of the CB and iris in each species, ranging from fish to mammals. The present comparative study concluded that the morphological structure of the CB and iris is the adaptation of species to either their lifestyle or survival in specific habitats.
摘要：
光学系统的一个关键组件是睫状体(CB)。这个身体分泌房水，这对于保持内部眼压以及晶状体和角膜的清晰度至关重要。组织学研究旨在提供以下脊椎动物类别的前眼房中CB和虹膜的形态差异：鱼（草鱼），两栖动物（阿拉伯蟾蜍），爬行动物（半水龟，扇脚壁虎,带牙的石龙子,埃及刺尾蜥蜴,阿拉伯有角毒蛇)，鸟类（普通鸽子，普通鹌鹑,普通凯斯特尔)，和哺乳动物(BALB/c小鼠，兔子,金色仓鼠,沙漠刺猬,较小的埃及人，埃及水果蝙蝠）。结果表明，每个物种的CB和虹膜的形态特征不同，从鱼类到哺乳动物。本比较研究得出的结论是，CB和虹膜的形态结构是物种对其生活方式或在特定栖息地中生存的适应。
