利用光镜和电镜对蛤蚧的卵巢结构和卵泡发育进行观察研究.成年蛤蚧卵巢由生殖基、卵巢壁和不同发育阶段的卵泡所组成.卵原细胞位于生殖基内.第一卵巢仅有一个生殖基.卵泡发育整个过程经历卵原细胞期、初级卵泡期、生长卵泡期和成熟卵汇期4个时期.在生长卵泡期,同形滤泡细胞转变成为形态和功能各异的3种细胞——小细胞、中间细胞和梨形细胞;随后再由异形细胞变为同形细胞,这种现象是有鳞类爬行动物独有的特征.卵泡一般由卵母细胞、滤泡细胞层和鞘构成.在每一卵巢中,一年最多只有一个卵泡能发育成为成熟卵泡.
The optical and electron microscopy were used to observe the ovarian structure and follicular development of baboons. The adult ovary consists of gonads, ovarian walls, and follicles of different stages of development. Oocyte is located in the genital. The first ovary has only one reproductive base. The whole process of follicular development experienced four stages: oocyte phase, primary follicle phase, growth follicle phase and mature egg convergence phase. In the growing follicle phase, homomorphic follicular cells are transformed into three types of cells with different shapes and functions—small cells, intermediate cells, and pear-shaped cells; then, they are transformed into blood cells of the same type. This phenomenon is scaly crawling. Unique animal characteristics. 2. Follicles generally consist of oocytes, follicular cell layers and sheaths. In each ovary, only one follicle at a time can develop into a mature follicle.
