What is being depicted in the histological photo below?

Follicular Atresia
(apoptosis of all follicles but the strongest, dominant follicle)
In the ovulatory phase there is an LH surge that causes two major things to happen. It causes the primary oocyte to complete meosis 1 and become a secondary oocyte that is arrested at metaphase II. It also promotes the formation of the stigma in the OSE and the follicle to rupture so the oocyte can be released into the uterine tube. This damage occurs via LH surge signalling the protelytic activity of what two cell layers?
A. Theca interna and Theca externa
B. Theca interna and murula granulosa cells
C. Theca externa and Tunica albuginea
D. Tunica albuginea and murula granulosa cells
Theca externa and Tunica albuginea
These two things are on the outer portion of the cell…

The stigma has been formed in the OSE, the follicle has ruptured, and the oocyte is out in the uterine tube. Now the OSE must be repaired, what two layers handle this repair
A. Theca interna and Theca externa
B. Theca interna and murula granulosa cells
C. Theca externa and Tunica albuginea
D. Tunica albuginea and murula granulosa cells
Theca interna and murula granulosa cells

The Luteal phase is when Leutinization occcurs and the corpus leuteum forms. How does the corpus leutuem form?
Corpus leutum forms after the follicle basal lamina breaksdown, causing blood vessels to empty into the antrum. That blood coagulates and forms the temporary corpus hemorrhagicum. Once the blood is absorbed, the Corpus Leuteum is left.

Mural Granulosa Cell
What does the granulosa lutein cell secrete in reponse to FSH and LH?
Progesterone and Estrogen
The theca lutein cells are derived from what cell?
Theca Interna
What does the theca luetin cell secrete in response to LH?
Progesterone and androstenedione (eventually can become testosterone)
