| Name: | oocyte stage II |
|---|---|
| Synonyms: | cortical-alveolar oocyte, oocytes stage II, previtellogenic oocyte, Stage 2 oocyte |
| Definition: | Oocyte part of stage II ovarian follicle. The stage II oocytes are characterized by the presence of cortical alveoli, a tripartite zona radiata (vitelline envelope), and a central germinal vesicle. |

| Name: | endoplasmic reticulum |
|---|---|
| Synonyms: | ER |
| Definition: | The irregular network of unit membranes, visible only by electron microscopy, that occurs in the cytoplasm of many eukaryotic cells. The membranes form a complex meshwork of tubular channels, which are often expanded into slitlike cavities called cisternae. The ER takes two forms, rough (or granular), with ribosomes adhering to the outer surface, and smooth (with no ribosomes attached). |
