| 内容記述 | In the present article, anatomical and histological observations were given on the reproductive organs of 36 specimens of N.pompilius collected in Fiji late in August and in September, 1983. A mature spermatophore in the spermatophore sac is observed to develop in most of the adult males. A developing ovary including oocytes of various sizes and a few full-grown oocytes are in most of adult females. The nucleus of the early spermatid begins to elongate remarkably. Crowds of mitochondria fuse one another to make two large mitochondria, and extremely elongate along the cylindrical nucleus. Numbers of microtubules surround the elongating nucleus and mitochondria resulting in a manchette structure. The acrosomal rods and vesicle are formed on the apical area of the cylindrical nucleus. Condensation of the chromatin occurrs during the elongation of nucleus. Two basal bodies lie in parallel to each other in a deep implantaion fossa of the nuclear envelope. The nucleus of mature spermatozoa in the spermatophore is extremely elongated with a length approximately 37 μm and diameters approximately 0.5×0.3 μm. Young oocytes have a germinal vesicle with a spherical nucleolus. They are surrounded by a flat follicle epithelium. According to the growth of the oocyte, the nucleus moves to one side of the oocyte surface, where the futured blastodisc is formed. On the opposite side follicle epithelium develops to a vast array of interdigitaion. A lot of microvilli are extended on the surface of the oocyte and the follicle cells. The follicle epithelium complex folding into the elder oocyte grows just like a meshwork. Yolk substance in the growing oocytes includes a lot of carbohydrate, especially acid mucopolysaccharide. They also include a lot of fatty substances. The biggest oocyte in the ovary has approximately 2.35g in weight. |
