摘要

摘要: 采用组织切片和电镜技术,对锯缘青蟹大颚器的形态结构进行了观察.大颚器位于大颚肌几丁质腱的后侧基部.腺细胞胞质丰盈,质膜大量内陷和作不同程度的卷绕,内含大量具管状脊的线粒体和滑面内质网.卵巢成熟时大颚器腺细胞内线粒体增多,少数线粒体形态异样,高尔基体易见,散布的小管状滑面内质网(tSER)少,高度汇合的tSER增多,大小形状不同的空泡数量明显增加,且近质膜分布,质膜内陷和卷绕程度加剧.表明此时锯缘青蟹大颚器的合成与分泌能力增强,其生理功能与卵巢发育密切相关.

Abstract: The paired mandibular organs are located at the base of the mandibular tendon.The plasmamem brane of the glandular cells is convoluted,especially at the adjaction to the hemolymph channels.The cytoplasm has numerous smooth endoplasmic reticulum and mitochondria with tubular cristae.In the maturation stage of the ovaries,the mitochondria grow up in number,a few of which change morpholog ically;the developed Golgicom plexes are frequently observed;the scatteredt SER reduces,while the highly convergedt SER increases;vastarrays of vesicles varying in size are located adjacent to the plasmamem brane;the degree of convo lution enhances.The structure change of this organ may associate with the increasing ability of synthesis and secretion of the mandibular organin .
