1
Q

Ovaries produce what?

A

Germ cells

2
Q

T/F the ovaries have only endocrine functions?

A

False- both endocrine and exocrine

3
Q

What two molecules are associated with endocrine function?

A

Estrogen

Progestogens

4
Q

What is the job of estrogen?

A

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

5
Q

What do progestogens do?

A

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

6
Q

What is the exocrine function?

A

The ovaries produce and ovulate a secondary oocyte

7
Q

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

A

True

8
Q

Ovarian follicles are found within the ____ of the ovaries.

A

cortex

9
Q

What is an ovarian follicle?

A

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

10
Q

The size of the oocyte indicates what?

A

The developmental state of the oocyte

11
Q

What are the three types of ovarian follicles?

A
  1. Primary follicles
  2. Growing follicles
  3. Mature or Graffian follicles
12
Q

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

A

Primordial germ cells–Oogonia–Primary oocyte

13
Q

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

A

okay

14
Q

What are the cells called that surround the developing follicle?

A

Theca folliculi

15
Q

Theca folliculi are made from which cells?

A

Stromal cells

16
Q

Theca folliculi are what type of tissue?

A

Connective tissue

17
Q

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

A

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

18
Q

What are the two cells of the corpus luteum?

A

Granulosa lutein cells

Theca lutein cells

19
Q

Granulosa lutein cells produce what?

A

progesterone

20
Q

Theca lutein cells continue to produce what?

A

estrogens

21
Q

Where does fertilization take place?

A

In the fallopian tubes

22
Q

What type of cells are found in the uterine tubes?

A
ciliated cells (help move oocyte towards uterus
secretory cells (produces nutritive fluid covering epithelium)
23
Q

T/F the fallopian tubes are muscular tubes?

A

truth

24
Q

What are the three layers of the uterus?

A

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

25
Q

The vaginal canal has what type of epithelium?

A

non keratinized stratified squamous epithelium

26
Q

The mammary glands are what?

A

tubuloalveolar apocrine sweat glands
