Flashcards in Female Repro Deck (36):
1

In general, what organs are in the female reproductive system?

2 ovaries, 2 fallopian tubes, uterus, vagina, external genitalia, mammary glands

2

The ovary is the female _______ producing both eggs and ________.

Gonad
Hormone

3

Where are the ovaries? How big are they?

A paired organ, one on each side, the size of an almond, in pelvic cavity
Lie on either side of the uterus

4

What is the capsule of the ovary?

tenia albuginea

5

What three ligaments hold the ovary in place?

Broad ligament
Ovarian ligament
Suspensory ligament

6

What does the broad ligament of the ovary do?
What is it?

Peritoneal “fold” that covers the uterus
Supports the fallopian tubes, uterus, vagina, and ovary

7

What do the ovarian ligament and suspensory ligament do?

Ovarian ligament- Anchors each ovary medially to the uterus
Suspensory ligament- Anchors the ovary laterally to the pelvic wall, vasculature travels thru it

8

The ovary is indistinctly divided into the ________ where eggs develop, and a superficial area, the ______ occupied by arteries and veins

Cortex
Medulla

9

How is the ovary supplied with blood?

Ovarian artery comes off abd. aorta and comes through suspensory ligament
Anastomosis with uterine artery, which comes from the internal iliac

10

Each egg develops in its own fluid-filled bubble-like ______. The follicle bursts open to release the ____ after the egg is finished developing.

follicle
egg

11

What is egg production called?

Oogenesis

12

When the ________ ______ (______ _____) enlarges, oocyte “sits” on a stalk on granular cells in an antrum (fluid-filled cavity), forms a bulge at the surface of ovary, and then ______ occurs.

Tertiary follicle- (Graafian follicle)
ovulation

13

If the egg is fertilized, meiosis II is completed and we now have a _______.

zygote

14

Corpus luteum is a "_______" body and corpus ________ is a "white" body.

Yellow
Albicans

15

How does the corpus lutea develop?

When the follicle ruptures, the egg goes out and the follicle collapses upon itself
This collapsed follicle develops into the corpus lutea

16

What hormone stimulates the development of the corpus lutea?

LH

17

What hormones does the corpus lutea secrete? What do they do?

progesterone and some estrogen, which prepares the uterus for possible pregnancy

18

If pregnancy occurs, the _____ will take over production of progesterone and estrogen from the corpus lutea

placenta

19

How is the corpus albicans formed?

Corpus luteum degenerates into an inactive bit of scar tissue, which is the corpus albicans

20

At what times does the corpus albicans form?

If pregnant- after 17 weeks the placenta takes over, get corpus albicans
If not pregnant- 8 days after ovulation, corpus luteum becomes the corpus albicans

21

Where is the fallopian tube? How long is it?

Locates at superior margin of the broad ligament
10 cm long tubes open into the uterus
Near the ovary, it opens into the peritoneal cavity

22

What are the 4 components of the fallopian tube?

Isthmus → Ampulla → Infundibulum → Fimbriae

23

On the fallopian tube, the ______ is a narrow section that enlarges as the ______. The infundibulum flares like a trumpet, ending in the finger-like projections called _______ to “catch” eggs.

Isthmus
Ampulla
infundibulum
fimbriae

24

What two kinds of cells are in the mucosa of the fallopian tube? What do they do?

1- ciliated columnar to advance egg
2- non-ciliated columnar to nourish the egg

25

What two layers make up the muscularis? What is the outermost layer of the fallopian tube called?

Muscularis- inner circular, outer longitudinal
Serosa

26

Where does fertilization usually occur?

In the ampulla of the fallopian tube

27

Describe the uterus. Simply, what does it do?

A hollow, muscular organ, 3 in long, 2 in wide, comparable to a pear
Houses and nourishes the developing embryo and fetus
Tilts over the urinary bladder

28

What are the three parts of the uterus?

1- Fundus- Superior, rounded portion
2- Body- Main portion, most of the uterus is the body
3- Cervix- Inferior, narrow portion. Projects into the vagina inferiorly

29

What are the three histo layers of the uterus?

Perimetrium
Myometrium
Endometrium

30

What is the perimetrium?

Outermost serous layer

31

What is the myometrium?

Bulk of the uterine wall
Bundles of smooth muscle sweep down from the fundus
Spiral around the uterus

32

What part of the uterus does oxytocin target?

Myometrium

33

Generally, what is endometrium?

Is the inner/mucosa layer of the uterus
Simple columnar epithelium, a thick lamina propria, numerous uterine glands

34

What are the layers of endometrium?

Stratum functionalis
Stratum basalis

35

What is the stratum functionalis?

Layer closest to the uterine cavity
Shed during menstruation
Site of attachment of embryo
This stratum is the ⅔ of the endometrium that is shed every month

36

What is the stratum basalis?

The deep layer of endometrium
This layer is permanent
Unresponsive to ovarian hormones
