Oogenesis

13. ____ become primary oocytes before birth.

Oogonia

4.The outer surface of the ovaries contains ____ epithelial cells.

Outer surface—germinal epithelial cells

2. What blood vessels supply the ovaries?

Ovarian artery and vein. There is alof of communication through the blood that carries hormones

10____is the ejection of the oocyte from the ripening follicle.

Ovulation The Protein hormone LH causes this happen.

What is a Gamate?

Sperm and an Ova, Egg. There both Haploid cells they only have 1 set of chromosome. It has to make the egg and kick it out. and too secrete hormones

What is the color and substance of an ovary

They are Pink and Yellow which indicates High Lipid.There are steroid hormones that are being produced here.

24. The ___ is a sugary coat that forms around the oocyte.

Zona pellucida

14. Primary oocytes begin meiosis but stall in ____of meiosis.

prophase I

11._____ is the structure that remains after the corpus luteum is no longer functional;no fertilization and there is no progesterone secreting in this area.

scar tissue.

30. The corpus luteum produces the hormone_____ and ____.

secretes progesterone & estrogen

8. List and describe the stages of development of the ovarian follicles.

-Primordial follicle- early stage of when we are born,stuck in prophase 1 of meiosis1. The lil ephtila cells that surround the oocyte are squamous flat cells. -Primary follicle - the epithelial cells go from flat squamous cells to cuibodial. This is when they are secreting something mainly estrogen. -Secondary follicle the gran multiply, a gap, fluid filled space, sugar coating of the oocyte -Late secondary follicle - filled gets so filled it gets kicked out. -Vesicular (Graafian)/Mature follicle

25. The ___ forms around the oocyte and is ovulated along with the oocyte

...

3 types form of circulating Estrogen. What is Estradiol

1. Estradiol - This is the most abundant; also the most Powerful. Very Potent. 2. Estrone - Weak 3. Estriol - Weak

1.There are _____________ovaries and they are paired.

2

32. The ____ is a scar that replaces the corpus luteum after about 10 days if no pregnancy occurs.

Corpus Albicans

The ___ develops after the oocyte is ruptured after ovulation

Corpus luteum; secretes progesterone(steroid) to maintain the uterine lining, just in case we have fertilization and inplantation

23. In the primary follicle the thecal cells & granulosa cells produce ___.

Estrogens

22.__from the adenohypophysis activates primodial follicles in ovary to develop into primary follicles.

FSH Follicle Stimulating Hormone FSH - (Protein) Released into general circulation

16. The secondary oocyte arrests in ______ and is ovulated.

Gets stuck in metaphase II

3.______ hold the ovaries in place.

Held in place by ligaments, they are connective tissues holding the ovaries and uterus in place. Suspensary Ligaments Blood Vessles that intertwine with the ligaments Ovarian Ligaments and Broad Ligaments that supports the fallopian tubes and the whole area

29. During the luteal phase the ruptured follicle collapses and forms the _____.

•Corpus Luteum

33.The hormone ____ triggers ovulation.

•Day 14 - LH triggers ovulation

35._______ levels surge about day 12 and produce a positive feedback on the pituitary resulting in a surge of ______.

•Estrogen, •Result—surge of LH

34. The hormone _____stimulates follicle growth, maturation and estrogen release.

•FSH & LH ® ovary

20.Describe the activites of the follicular phase of the ovarian cycle in regard to hormone control.

•FSH and LH targets the Ovary and it stimulates the Primordial follicles to start to grow, so as the follicles grow they will develop into primary follicles and there going to grow some more and mature some more making more and more granulose cells as they go along. •So As the FSH and LH targets the Ovary the developing follicles begin to secrete Estrogen, so the lil follicles start to secrete Estrogen from the lil granulose cells. •Estrogen (Steroid)goes to general circulation when its secreted •As Estrogen increases it begins to have an effect on the feedback loop it starts to inhibit. The estrogen will rise and we will have enough estrogen it stops inhibiting it and we have a surge in LH.

6. The functions of the ovaries include: they are the female _____, produce ______ and secrete the hormones _____ and _____.

•Female gonads •Produce female gametes (ova) •Secrete Primary hormones—estrogen & progesterone, -Ovulation - it has to make it and kick out the egg

7. In ovarian development the follicle contains an immature egg an ______ surrounded by ____ which are one cell layer thick and the ____ cells when there is more than one layer present.

•Follicle contains an immature egg (oocyte) surrounded by -Follicle cells (one cell layer thick) they are made by -Granulosa cells (when more than one layer is present).They are epithelial cells that begin to secrete hormones.

18. During the ovarian cycle the ____phase lasts from days 1 through 14 and the _____ phase lasts from days 14 through 28.

•Follicular phase (days 1-14) The first 14 days. •Luteal phase (days 14-28) The Last 14 days.

27. Around 14th day oocyte floats and the _ surges and ovulation occurs

•LH surges and ovulation occurs

5. The ovarian follicles are found in the____ of the ovary.

•Ovarian follicles are in the cortex around the perimeter of the ovary

19. ____ occurs midcycle.

•Ovulation occurs midcycle

17.If penetrated by sperm the second oocyte completes meiosis II, yielding an ____ (the functional gamete) and a ____.

•Ovum (the functional gamete) •Second polar body sometime it gets split here and split again

15. Each month after puberty, a few primary oocytes are activated, one is selected each month to resume meiosis I and the result is two haploid cells a _____ and the ____.

•Secondary oocyte - 1 set of chromosome •First polar body - DNA but does not have much cytoplasm - sometimes they get stuck on the side and degenerate.

26.___ stimulates primary oocyte to complete meiosis I and now the oocyte is ready for ovulation.
