Flashcards in Female Reproductive System- Histo Deck (26):
1

Ovaries produce what?

Germ cells

2

T/F the ovaries have only endocrine functions?

False- both endocrine and exocrine

3

What two molecules are associated with endocrine function?

Estrogen
Progestogens

4

What is the job of estrogen?

promote growth and maturation of internal and external sex organs
Promote cyclic changes in uterine mucosa
Development of secondary sex characteristics

5

What do progestogens do?

prepare internal sex organs for pregnancy and (uterus) and prepare mammary glands for lactation

6

What is the exocrine function?

The ovaries produce and ovulate a secondary oocyte

7

T/F ovaries and testes have the same embryological origin?

True

8

Ovarian follicles are found within the ____ of the ovaries.

cortex

9

What is an ovarian follicle?

It is an oocyte surrounded by one or more layers of epithelial cells.

10

The size of the oocyte indicates what?

The developmental state of the oocyte

11

What are the three types of ovarian follicles?

1. Primary follicles
2. Growing follicles
3. Mature or Graffian follicles

12

What is the process of the development of a germ cell to an oocyte?

Primordial germ cells--Oogonia--Primary oocyte

13

There are like 5 million ovarian follicles in the fetus. By puberty you only have like 300k but only about 400 are ovulated

okay

14

What are the cells called that surround the developing follicle?

Theca folliculi

15

Theca folliculi are made from which cells?

Stromal cells

16

Theca folliculi are what type of tissue?

Connective tissue

17

What are the two parts of the theca folliculi? What are their jobs?

Theca interna- in response to androgens, these secrete androgens (precursors to estrogen)
Theca externa- fibrous outer portion

18

What are the two cells of the corpus luteum?

Granulosa lutein cells
Theca lutein cells

19

Granulosa lutein cells produce what?

progesterone

20

Theca lutein cells continue to produce what?

estrogens

21

Where does fertilization take place?

In the fallopian tubes

22

What type of cells are found in the uterine tubes?

ciliated cells (help move oocyte towards uterus
secretory cells (produces nutritive fluid covering epithelium)

23

T/F the fallopian tubes are muscular tubes?

truth

24

What are the three layers of the uterus?

Perimetrium- outer connective tissue
Myometrium- middle/thicketslayer, smooth muscle here
Endometrium- basal and functional layers- functional layer changes thickness

25

The vaginal canal has what type of epithelium?

non keratinized stratified squamous epithelium

26

The mammary glands are what?

tubuloalveolar apocrine sweat glands
