Now let's focus in on the following pathway that basically describes the maturation, the development of that primary oicide into that ovum. So because we're assuming this female individual has been born, that means all these oocides are now primary oocides. All the Ogonia differentiated into primary oocides. Now, these oocides, the primary oocides, do not exist as individual cells. Instead these Oocides are found inside these fluid filled structures known as Ovarian follicles. So an Ovarian follicle is the fluid filled structure found inside the Ovary that contains not only that developing Oicide but it also contains important cells, other different types of cells that also assist in the process of ogenesis.
