1
Q

What is the endocrine and exocrine function of the ovaries

A

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

2
Q

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

A

estrogens

3
Q

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

A

progestones

4
Q

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

A

ovarian follicles

5
Q

What indicates the developmental state of the oocyte

A

size of the ovarian follicles

6
Q

What are the three basic types of ovarian follicles

A

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

7
Q

What stage of the follicle has squamous epithelium

A

primordial follicle

8
Q

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

A

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

9
Q

How many ovarian folic in the fetus? ovulated?

A

600,000-800,000 at birth

~400 ovulated (lost via atresia)

10
Q

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

A

theca folliculi

11
Q

The theca follicli differentiates into which two parts

A

theca interna

theca externa

12
Q

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

A

theca interna

13
Q

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

A

theca externa

14
Q

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

A

antrum (secondary Antral follicles)

15
Q

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

A

FSH; from pituitary gland

16
Q

This is made of glycoproteins; vital for sperm attachment

A

zona pellucide

17
Q

This is made follicular cells that have grown

A

stratum granulosum (granulosa cells)

18
Q

What begins the secondary oocyte

A

metaphase of meiosis, this will be ovulated

19
Q

These are the two cells of the corpus luteum

A

granulosa lutein cells

theca lutein cells

20
Q

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

A

granulosa leutin cells

21
Q

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

A

theca leutin cells

22
Q

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

A

day 14

23
Q

This is formed from the degeneration of the corpus luteum

A

corpus albicans

24
Q

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

A

uterine (Fallopian) tube

25
Q

What makes up the wall of the uterine tube

A

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

26
Q

What type of cells are found in the uterine tube

A

ciliated cells

secretory cells

27
Q

These cells help move the oocyte toward the uterus

A

ciliated cells

28
Q

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

A

secretory cells

29
Q

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

A

perimetrium

30
Q

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

A

myometrium

31
Q

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

A

endometrium

32
Q

What are the two parts of the endometrium

A

basal layer

functional layer

33
Q

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

A

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

34
Q

What does the basal layer of the endometrium contain

A

uterine glands

35
Q

What type of epithelium is in the vagina

A

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

36
Q

What are the two types of primary oocytes

A

unilaminar and multilaminar

will see either 1 or 2+ layers
