Ovary with Numerous Primordial Follicles and Two Primary Follicles Primordial follicles contain oocytes that are not stimulated to complete the first meiotic division. Two primary follicles each contain an ovum with nucleus and clear surrounding cytoplasm. Thin, clear zona pellucida is surrounded by a ring of even cuboidal cells, the corona radiata. (X25)
