Flashcards in EX3 Histology - Female Reproductive System Deck (36):
1

What is the endocrine and exocrine function of the ovaries

endocrine - produce estrogens and progestogens; steriodogenesis
exocrine - produce the female gamete (ovum); gametogenesis; produce and ovulate a secondary oocyte

2

These promotes the growth and maturation of internal and external sex organs, promotes menstruation and development of secondary sex characteristics

estrogens

3

These prepare internal sex organs (uterus) for pregnancy by promoting changes in endometrium and mammary glands for lactation

progestones

4

These are found within the cortex of the ovaries and composed of an oocyte surrounded by one or more layers of epithelium

ovarian follicles

5

What indicates the developmental state of the oocyte

size of the ovarian follicles

6

What are the three basic types of ovarian follicles

primordial follicles
growing follicles (primary and secondary)
mature (or Graafian) follicles

7

What stage of the follicle has squamous epithelium

primordial follicle

8

In the third month of fetal life, what happens, what stage of meiosis is it stuck

PGCs migrate from yolk sac; the oogenia divide into primary oocyte and rest at prophase of meiosis 1

9

How many ovarian folic in the fetus? ovulated?

600,000-800,000 at birth
~400 ovulated (lost via atresia)

10

This is a sheath of connective tissue cells that develop from the stromal cells surrounding the developing follicle; found external to the basal lamina

theca folliculi

11

The theca follicli differentiates into which two parts

theca interna
theca externa

12

These are cubodial secretory cells and in response to LH, they synthesize and secrete androgens (estrogen precursor); endocrine; fibroblasts, collagen bundles and lots of vessels

theca interna

13

This is the fibrous outer portion; smooth muscle cells, fibroblasts, and collagen bundles

theca externa

14

This is produced by(and is) granular cells; produces follicular fluid and is indicative a secondary follicle

antrum (secondary Antral follicles)

15

This hormone stimulates follicle cells to grow, increase in size, and the growth of an oocyte

FSH; from pituitary gland

16

This is made of glycoproteins; vital for sperm attachment

zona pellucide

17

This is made follicular cells that have grown

stratum granulosum (granulosa cells)

18

What begins the secondary oocyte

metaphase of meiosis, this will be ovulated

19

These are the two cells of the corpus luteum

granulosa lutein cells
theca lutein cells

20

These cells undergo hypertrophy (30μm); centrally located cells derived from granulosa cells; begins to produce progesterone

granulosa leutin cells

21

These cells slightly increase in size (15μm); peripherally located cells derived from cells of the theca intern; produce estorgens

theca leutin cells

22

At what stage will the granulosa and theca leutin cells inactivate and lyse

day 14

23

This is formed from the degeneration of the corpus luteum

corpus albicans

24

This is a paired muscular tube 12cm in length, where fertilization takes place

uterine (Fallopian) tube

25

What makes up the wall of the uterine tube

folded mucosa with simple columnar epithelium, thick muscularis (smooth muscle) and serosa

26

What type of cells are found in the uterine tube

ciliated cells
secretory cells

27

These cells help move the oocyte toward the uterus

ciliated cells

28

These cells are dark staining, have apical budges and produce a nutritive fluid covering epithelium

secretory cells

29

This is the outer connective tissue later (adventitia or serosa) of the uterus

perimetrium

30

This is the middle thick layer of the uterus made up of bundles of smooth muscle separated by connective tissue and blood vessels; four poorly defined layers

myometrium

31

This is the inner layer of the uterus made up of simply columnar epithelium with both ciliated and secretory cells with lamina propria; contains uterine glands

endometrium

32

What are the two parts of the endometrium

basal layer
functional layer

33

What happens to the functional layer of the endometrium during menstrual flow

it thickens by changes in ovarian hormones and the majority is sloughed away during menstruation

34

What does the basal layer of the endometrium contain

uterine glands

35

What type of epithelium is in the vagina

wall; mucosa, muscular, adventitia
mucosa = nonkeratinized stratified squamous epithelium
smooth muscle = inner circular, outer longitudinal

36

What are the two types of primary oocytes

unilaminar and multilaminar
will see either 1 or 2+ layers
