1

Ovaries are lined by ______

simple cuboidal. Aka germinal epithelium (at the periphery of ovary)

o Called "germinal" epith, but NO germ cells in it

o Simple cuboidal epithelium is the location of most ovarian cancers

2

______ is the location of most ovarian cancers

Simple cuboidal/columner/squamous germinal epithelium -- outer lining of ovary 

3

Directly beneath the germinal epithelium (lining of ovaries) is _______

tunica albuginea (dense connective tissue)

4

In females tunica albuginea in _____

In males also a tunica albuginea in ______ and _____

Ovaries have TA

Testes and penis has TA

5

What is in the Cortex of ovaries?

follicles (with oocyte) that are at different stages of development 

6

What is in Medulla of ovaries?

connective tissue and blood vessels

7

Functions of ovaries

Exocrien: Production/storage of oocytes

Endocrine: sex hormone production

8

Internal organs of Female reproductive system, include _______ (4 things)

  • 2 ovaries
  • 2 uterine tubes (oviducts, fallopian tubes)
  • uterus
  • vagina

9

What 3 layers must a sperm cross to fertilize this?

Corona radiata - Zona pellucida - Plasma membrane.

 

10

External genitalia, include ___ 

labia minora

labia majora

clitoris

vestibular glands

 

Mammary glands are considered part of the Reprod system bc they're under endocrine control and develop during pregnancy.

11

12

initiation of pubertal development occurs at age ____, is called___

12-13 year old

Menarche - first menses

13

____ is the cyclic appearance of menses associated with fertility 

Menstrual cycle

             

14

Menopause

-- when does is occur, what it signifies?

  • cycle becomes irregular and eventually disappears in favor of a tonic status
  • ~ 50 year

15

exocrine function of ovary ____

endocrine function of ovary ____

production of gametes (exocrine)

 sex hormone production (endocrine)

16

Which organ is almond shaped?

ovary

17

Layer of the ovary out to in:

outer layer - a simple squamous/cuboidal/columnar germinal epithelium  

tunica albuginea (dense connective tissue)

cortex - containing ovarian follicles in various stages of development. 

medulla - occupies central region of ovary, consists of blood vessels and connective tissue.

18

Which layer has the folicles?

cortex

19

Primordial follicles

- present before birth

- consists of a primary oocyte arrested in (dictyotene) meiotic prophase I surrounded by a layer of flattened follicular cells. 

20

Outside of follicular cells are ____. 

stromal cells

21

At puberty cyclic secretion of FSH stimulates ___ to develop and produce _____ . 

groups of follicles develop and produce estrogen

22

3 things that happen every 28 days after puperty: 

- 20 primordial follicles are recruited by FSH. 

- Their follicular cells acquire more FSH receptors

- these flattened folicular cells become more columnar (now called granulosa cells). 

23

Primary Unilaminar Follicles - consists of _____

a primary oocyte surrounded by one layer of granulosa cells (unilaminar)

24

Primary Multilaminar Follicles

- consists of a primary oocyte surrounded by more than one (multilaminar) layers of granulosa cells.

25

The ___ cells deposit an extracellular coat (zona pellucida) onto the _____.  

granulosa and oocyte together deposit zona pellucida onto the primary oocyte

26

The zona pellucida is traversed by ____

delicate cytoplasmic processes from granulosa cells (filopodia) and microvilli projecting from the oocyte

27

stromal cells differentiate to form ______

theca interna

28

what does theca interna look like? 

- has vascularizations-- needs to circulate the hormones it produces 

- fat lobues inside the cell bc makes steroid hormones

29

4 segments of the oviduct

infindibulum

ampulla

isthmus

pars interstitialis (intramural portion)

30

fimbriae

trap and pull ovum into infindibulum at ovulation

31

3 layer of the wall of oviduct 

a mucosa

a muscularis 

a serosa of visceral peritoneum

32

Mucosal folds are most prominant in ____, and decrease in height and length near ____

most prominant -- ampulla region

less in Isthmas

33

mucosal folds are lined by ___

2 types of estrogen dependent cells: 

1) ciliated cells -- help move ovum through oviduct 

2) secretory (non ciliated)-- secrete protein to nurture potential zygote

34

Ovum is supended in the oviductal fluid that is formed by ___ 

transudation and E stimulated secretions from secretory cells 

35

order of layers in oviduct wall (outside to in)

serosa --> longitudinal --> circular layer of smooth muscle-> lamina propria --> ciliated simple columner epithelium--> lumen

(aka. serosa --> muscularis--> mucosa --> lumen)

36

which layer of the uterine tube is connected to broad ligament? 

outer serosa

37

___ stops secretory activity stimulated by estrogen in the oviduct cells 

progesterone 

38

oviduct can support blatocyst for ____

3-4 days post ovulaton 

39

if fetus continues to develop in ___ it's an ectopic pregnancy. ___ acts like the endometrium

in the oviduct

lamina propria of oviduct acts like endometrium and forms desidual cells 

40

blockage of ___ can result in indertility 

uterine tube

41

42

3 parts of the uterus

corpus --body

fundus -- highest part of corpus, above entrance of oviduct

cervix -- neck

43

3 layers of uterine wall 

endometrium 

myometrium 

perimetrium 

44

hypertrophy vs. hyperplasia

Hypertrophy -- enlargement of existing cells

hyperplasia -- an increase in the number of normal cells.
