Female Reproductive System Pt. 1

Question 1

What do the ovaries produce?

Answer 1

Eggs (oocytes) and ovaries

Question 2

Which part of the Female Reproductive System transfers the egg?

Answer 2

Uterine

Question 3

Where does fetal development occur?

Answer 3

The uterus

Question 4

What is the Birth Canal

Answer 4

The vagina

Question 5

What is the peritoneal membrane covering the ovary?

Answer 5

Germinal Epithelium

Question 6

Explain Ovarian Follicles

Answer 6

Contain “oocyte” in various stages of development and secretes estrogen which helps in repair/growth of uterine tube, regulation of cycle, etc.

Question 7

Give me the stages of Follicular Development from #1-#5 and explain

Answer 7

1) Primordial Follicle: single layer of squamous cells
2) Primary Follicle: layers of cuboidal granulosa cells (secrete estrogen)
3) Secondary Follicle: antral cavity forms
4) Graffian Follicle: where the follicle is MATURE and oocyte ovulates
5) Ovulation: Follicle ruptures= release of oocyte

Question 8

What is it called when the follicle is mature and the oocyte ovulates

Answer 8

Graafian Follicle

Question 9

Structures of the Ovum (where the sperm races too) (4)

Answer 9

1) Zona Pellucida: thick outer membrane for protection
2) Corona Radiata: vital protein to cell
3) Vitelline Membrane: Plasma Membrane of egg
4) Ooplasm: the cytoplasm

Question 10

What is a Corpus Luteum?

Answer 10

• when the follicle is empty after ovulation

Question 11

What does Corpus Luteum excreted

Answer 11

1) progesterone (completed lining of uterine)
2) estrogen (helps progesterone)
3) relaxin (relaxes uterine muscles)
4) inhibin (decreases secretion of fsh and lsh)

Question 12

What is it called when the corpus luteum dies and is a white scare tissue

Answer 12

Corpus Albacians

Question 13

What is Oogenesis

Answer 13

It’s is where the oogoinia turned to a oocyte. And where a oocyte turns into a ovum

Question 14

What happens when full maturation occurs

Answer 14

Puberty (where gonadotrophin hormones occur)

Question 15

What type of cells are oogonia?

Answer 15

Diploid cells but will turn into haploid cells (secondary oocyte) after meiosis 1

Question 16

Explain the Oogenesis stages (6 steps)

Answer 16

Just look at reviewer if correct

Question 17

Each month over 20 primary oocytes become secondary oocytes but only one survives to be ovulated in the

Answer 17

Graafian Follicle

Question 18

Ovulation occurs in

Answer 18

Meiosis 2

Question 19

What occurs when a sperm and zygote unite

Answer 19

A zygote

Question 20

What is a Uterine

Answer 20

4 inch tubes that extend from ovaries to uterus

Question 21

Parts of the Uterine (4)

Answer 21

1) Infundibulum
2) Fimbriae
3) Ampulla
4) Isthmus

Question 22

1) Infundibulum

Answer 22

funnel shaped portion near ovaries

Question 23

2) Fimbriae

Answer 23

Finger-like process

Question 24

3) Ampulla

Answer 24

Center of the uterine/ commonly where fertilization occurs

Question 25

4) Isthmus

Answer 25

Narrowest portion that connects/joins to the uterus

Question 26

What are the 3 layers of the Uterine and explain what is Mucosa

Answer 26

1) Mucosa: (simple ciliated columnar epithelium) has cilia that moves the ovum or secondary oocyte torwards the Ovum 2) Muscularis 3) Serosa

Question 27

What are Peg Cells?

Answer 27

Peg Cells secrete fluid to nourish/ provide nourishment to the Ovum

Question 28

What are the 3 changes that occur when estrogen is released during menstruation in order to capture the egg?

Answer 28

1) the uterine moves closer to the ovaries 2) the Fimbriae ends beat more rapidly 3) the ciliated cells in Fimbriae increase of ciliation

Question 29

First step to fertilization process

Answer 29

1) the ovum is picked up by the Fimbriae and is moved by the cilia

Question 30

Sperm Journey and Travel

Answer 30

Explain and check reviewer

Question 31

Approaching Ovulation

Answer 31

Check reviewer

Question 32

Fertilization

Answer 32

Check reviewer

Question 33

What is the enzyme that the sperm releases in order to penetrate/ poke through the outer layer (zona pellucida) of the Ovum?

Answer 33

Hyaluronidase

Question 34

Zygote Formation

Answer 34

Check reviewer

Question 35

Fertilization is most likely to occur if

Answer 35

-Intercourse happens 48 hours before ovulation and 24 hours after ovulation - both sperm and the ovum can only survive 2-3 days

Question 36

What are the part/ anatomy of the Uterus?

Answer 36

1) site of menstrual cycle and fetal development 2) fundus, body, isthmus and cervix

Question 37

Layers/ Histology of Uterus

Answer 37

1) Endometrium (inner) 2) Myometrium (middle) 3) Perimetrium (outer)

Question 38

1) Endometrium

Answer 38

- simple columnar epithelium w/ glands and connective tissue - Functional layer: sheds of during menstruation - Basal Layer: regenerates the functional layer every month

Question 39

2) Myometrium

Answer 39

- has 3 layers w/ smooth muscle

Question 40

3) Perimetrium

Answer 40

Visceral layer of the uterus
