团头鲂排卵前的卵母细胞由外向内被鞘膜层基膜和颗粒层包围着。鞘膜层由鞘膜细胞和胶原纤维组成,鞘膜细胞的细胞质中充满了微丝。颗粒层由特殊颗粒细胞和颗粒细胞组成,特殊颗粒细胞的细胞质中含丰富的滑面内质网和具小管状内嵴的线粒体,表现出与类固醇激素合成有关的细胞器特征,颗粒细胞的细胞质中则含有发达的粗面内质网和具板层状内嵴的线粒体。
Oviduct oocytes before ovulation by the outer sheath surrounded by the basement membrane and granular layer. The sheath consists of the cells of the sheath and the collagen fibers, and the cytoplasm of the sheath cells are filled with microfilaments. The granular layer is composed of special granulosa cells and granulosa cells. The cytoplasm of special granulosa cells is rich in the glomerulus endoplasmic reticulum and mitochondria with small tubular inner crest, showing the organelle characteristics related to steroid hormone synthesis. The cytoplasm of granulosa cells It contains the developed rough endoplasmic reticulum and lamina cristae with mitochondria.
