7

Name the ovarian follicle stage:

Most primitive type, consisting of a primary oocyte surrounded by a single layer of squamous cells

8

Name the ovarian follicle stage:

Arrested at 1st meiotic prophase (diploid: N= 46)

Primordial follicle

9

Name the ovarian follicle stage:

1.5 M at birth, 400k at puberty

Primordial follicle 

10

Name the ovarian follicle stage:

Consisting of a primary oocyte surrounded by one or more layers of cuboidal cells that are now called "granulosa cells"

Primary follicle

11

Name the ovarian follicle stage:

Ca. 20 form each month

Primary follicle

12

Name the ovarian follicle stage:

Contains a primary oocyte, many layers of granulosa cells, and a fluid-filled space called antrum

Secondary follicle 

13

What is the function of antrum in the secondary follicle 

contains serous fluid that increases in volume as ovulation nears

14

Name the ovarian follicle stage:

contains a primary oocyte that is surrounded by two protective structures called zona pellucida and corona radiata  

Secondary Folicle

15

What are the names of the two protective structures that surround the primary oocyte of the secondary follicle?

zona pellucida

corona radiata

16

Each month a few _______ follicles become ______ follicles, and the others _______.

primary; secondary; degenerate 

17

Name the ovarian follicle stage:

Also called mature follicle 

Vesicular follicle

18

Name the ovarian follicle stage:

Contains a secondary oocyte surrounded by the zona pellucida and the corona radiata, an enlarged antrum, and many layers of follicle cells

Vesicular follicle

19

Name the ovarian follicle stage:

oocyte has completed 1st meiotic division, is in 2nd meiotic division. (haploid, N = 23)

Vesicular follicle 

20

 

Each month ____ secondary follicles become _______ follicles 

 

1 or 2; vesicular 

21

Name the ovarian follicle stage:

eventually ruptures & releases its secondary oocyte (ovulation) which will complete meiosis if fertilized 

Vesicular follicle 

22

Name the ovarian follicle stage:

Following the rupture of the vesicular follicle and the expulsion of the oocyte (ovulation), the remnants of the follicle (minus the oocyte) become this stage

Corpus luteum

23

Name the ovarian follicle stage:

secretes progesterone and estrogen, which stimulate growth of the uterine endometrium

Corpus luteum

24

Name the ovarian follicle stage:

When the corpus luteum regresses, it turns into a white connective tissue scar

Corpus albicans

25

Name the ovarian follicle stage:

Yellowish, collapsed folds of granulosa cells

Corpus luteum 

26

Name the ovarian follicle stage:

Whitish connective tissue scar, remnant of a degenerated corpus luteum 

corpus albicans

27

These extend laterally from both sides of the uterus

uterine tubes

28

What is usually fertilized in the lateral part of the uterine tube?

the secondary oocyte

29

How long does it take for pre-embryo to travel from the uterine tube to the lumen of the uterus 

approximately 3 days

30

usually, how long are uterine tubes

10-12 cm

31

32

List the continuous regions of the uterine tubes

33

Name the uterine tube region:

lateral opening of the tube encircled by fingerlike projections called fimbriae

Infundibulum 

34

Name the uterine tube region:

Name the uterine tube region:

Just medial to the ampulla and represents about 1/3 of entire length of uterine tube.

Isthmus

36

Name the uterine tube region:

interstitial segment; continuous with the uterus

Uterine part
