Cytoplasmic inclusions in the oogenesis of ophiocephalus punctatus

Summary TheGolgi apparatus can be seen in the usual juxtanuclear position in a very young oocyte. Later, the mass increases in size and resolves itself into very minuteGolgi spheres which disperse gradually in the general cytoplasm. There is some evidence of the infiltrati on of theGolgi bodies from the follicular epithelium to the egg. The granular mitochondria arise also in the juxtanuclear area, and with the increase in the size of the oocyte they get dispersed in the cytoplasm. The filamentar and beaded mitochondria appear in the older oocytes. Fatty yolk arises through the agency of theGolgi bodies by the swelling of aGolgi granule or by the deposition of new material on the concave side of one or more crescenticGolgi bodies. Albuminous yolk appears to be formed directly or indirectly by mitochondria. With 8 figures in the text.
