Nuclear profiles were markedly abnormal, plasmalemma withdrawal (arrowheads) could be seen and the profiles of endoplasmicreticulum were dilated (a). Note the smooth and rough endoplasmicreticulum and gap junctions between theca-interna cells. In the cortex of the oocytes the cisternae of the endoplasmicreticulum were no longer present. These complexes appear occasionally to be associated with vesicles of smooth endoplasmicreticulum. Microtubules and the endoplasmicreticulum are highly interdependent structures. The tegument is a syncytial stratum, laden with membrane-bound, electron-lucid and electron-dense vesicles, mitochondria, ribosomes and smooth endoplasmicreticulum. One interesting protein is calreticulin, a calcium-binding protein that, in mammals, is normally located in the endoplasmicreticulum. Concentric-whorled membranes, having a granular appearance resembling the ribosomes of rough endoplasmicreticulum, float in the pseudocoelom between somatic muscles, reproductive tract and intestine. Note the granular appearance of the cytoplasm and the presence of areas of expanded granular endoplasmicreticulum (gar). Two layers of membrane, derived from the endoplasmicreticulum, are incorporated as internal lipid membranes. The rachis cytoplasm contains mitochondria, extensive rough endoplasmicreticulum, and electron-dense granules. The gland contains glycogen deposits, and rough endoplasmicreticulum distended into cisternae with granular material. The cell cytoplasm consists of few mitochondria, granules, endoplasmicreticulum, and vesicles. The ' factories ' of crystalline material are comprised from seemingly specialized mitochondria and rough endoplasmicreticulum elements.
