| 中文摘要: |
| 对象山港自然海区中的嘉庚蛸(Octopus tankahkeei)雌性生殖系统的组织学结构进行了研究。结果表明,雌性生殖系统由卵巢、输卵管、输卵管腺组成。卵巢单个、球形,内包裹滤泡细胞围成的卵子,输卵管1对,开口于外套腔中部,每条输卵管中部膨大形成圆球状的输卵管腺。近端输卵管内具两瓣蘑菇状突起,上有不规则短指状分枝,突起嵌入管腔中,远端输卵管中无大的突起,血管位于突起和肌肉层之间。输卵管腺辐射型,由中央腔、纳精囊和输卵管腺体腔3部分构成,中央腔外层有24个大小不等的纳精囊。生殖季节,输卵管和纳精囊中可见大量未激活的精子。根据滤泡细胞形成褶皱的数目和比例对卵巢发育分期划分为4期:卵黄合成前期、卵黄合成早期、卵黄合成盛期和卵黄合成后期。 |
| 英文摘要: |
| The morphological structure of female reproductive system of Octopus tankahkeei was investigated from August,2002 to December,2003. The female reproductive system of O.tankahkeei, like many cephalopods,is composed of three parts morphologically: ovary,oviduct,and oviducal gland.The ovary is a single structure,which contains oocytes at different stages.The oocytes are surrounded by a layer of columnar follicle cells which enfold into the oocyte cytoplasm and their nuclei are arranged along the longitudinal axis of the cells.Different from proximal oviduct,mushroom-like protruding enwrapped by many finger-like folds lies in the distal oviduct.The oviducal gland can be divided into three parts: central lumen,spermathecaes,and gland tissue.The twenty-four spermathecaes are special parts in oviduct gland which contain spermatozoa after coupling.We propose to divide the ovarian cycle of O.tankahkeei into four phases: previtellogenesis,early vitellogenesis,full vitellogenesis,and late vitellogenesis phases. |
