Comparative Embryology of the Adenohypophysis of Actinopterygian Fishes

这项研究是关于放射鳍鱼类(放线蕨类)解剖的合作研究计划的第三项主要工作，放线鳍鱼是一个包含大约一半活着的脊椎动物的群体。该项目详细地比较描述了在头顶部发育的四个器官系统的早期胚胎学，包括垂体腺(垂体腺)、鼻腺、粘附腺和孵化腺。腺垂体之所以受到重视，是因为它既是解释脊椎动物头部发育和历史的中心，也是比较解剖学、胚胎学和内分泌学研究的统一体。近50年来，鳍鱼的比较胚胎学一直被忽视。利用扫描电子显微镜和现代组织学对几种原始鳍鱼胚胎的综合系列进行研究，将有助于解决许多百年来的争议。此外，鱼类更适合对器官系统进行详细的胚胎学和发育研究，从这些比较数据中产生的数据将提供宝贵的信息，使人们能够解释脊椎动物头部及其许多器官系统的发育模式。

This research is the third major effort in a collaborative research program on the anatomy of ray-finned fishes (actinopterygians), a group containing about half of living vertebrates. This project concerns detailed comparative descriptions of the early embryology of a cluster of four organ systems that develop at the rostral tip of the head including the hypophysis (pituitary), nose, adhesive and hatching glands. The adenohypophysis has been stressed because it is both central to interpreting the development and history of the vertebrate head and unites studies of comparative anatomy, embryology, and endocrinology. %%% For approximately 50 years comparative embryology of ray-finned fishes have been neglected. The use of scanning electron microscopy and modern histology to study comprehensive series of embryos of several primitive ray-finned fish will help to resolve many century-old controversies. In addition, fishes are better suited for detailed embryological and developmental studies of organ systems, and the data produced from these comparative data will provide valuable information that will allow one to interpret patterns of development of the vertebrate head and its many organ systems.
