In the following ovary labeled diagram, we have Granulosa Cells, Oocyte, Corpus Albicans (degenerated Corpus Luteum), Corpus Luteum (after ovulation, granulosa cells divide rapidly to form the corpus luteum), developing Corpus luteum, Corona Radiata (during ovulation, the oocyte is released from the follicle, along with surrounding granulosa cells called the corona radiata), Ovulated secondary oocyte, the mature follicle (forms when the fluid-filled vesicles consolidate into one antrum), Antrum, Outer Theca (capsule around the follicle), Inner Theca, Secondary Follicle (fluid-filled vesicles develop among granulosa cells), Zona pellucida, late primary follicle, Early primary follicle (develops as the granulosa cells become enlarged), and more.
