Flashcards in Histology of the female reproductive tract Deck (23):
1

At what stage in development do germ cells from the yolk sac invade the ovaries and begin to proliferate?

Week 6

2

What is oogenesis?

The development of oocytes from oogonia

3

What is folliculogenesis?

The growth of the follicle, which consists of the oocyte and any associated support cells.

4

Before birth; at what stage does meiosis halt?

Prophase 1

5

At what stage is meiosis halted prior to fertilisation?

Metaphase 2

6

What type of cells in the ovary are responsible for the production of oestrogen?

Theca cells

7

Where in the fallopian tube does fertilisation occur?

Ampulla

8

What kind of mucosa lines the ampulla of the uterine tube?

Simple columnar epithelium with ciliated and secretory cells. this is surrounded by a layer of smooth muscle.

9

What is epithelium of the isthmus of the fallopian tube?

Secretory with a few ciliated cells.

10

What are the two types of tissue in the endometrium and what is their function?

1. Stratum Functionalis: This undergoes monthly growth, degeneration and loss
2. Stratum Basalis: This is reserve tissue that regenerates the functionalis.

11

What name is given to the part of the endometrium that undergoes monthly growth, degeneration and loss?

Stratum Functionalis

12

What is the name given to the part of the endometrium that acts as a reserve tissue that regenerates the functionalis?

Stratum Basalis

13

What do the glands secrete during the secretory phase of the menstrual cycle?

Glycogen

14

What happens to cause the shedding of the lining in the uterus? (On a histological level)

Arterioles in the functionalis undergo constriction; depriving the tissue of blood and causing ischaemia.

15

What is the most common part of the cervix to undergo neoplastic change?

Transition zone

16

Describe the two parts of the epithelium of the cervix.

On the vaginal side; stratified squamous spithelium
Mucous secreting simple columnar epithelium

17

What glands secrete cervical mucus?

Endocervical glands

18

At what time in the menstrual cycle in cervical mucous thin and watery?

Proliferative (to allow passage of sperm)

19

At what time in the menstrual cycle is cervical mucous thick and viscous?

Following ovulation (to prevent the passage of sperm and microorganisms)

20

Describe the four histological layers of the vagina

1. Non keratinised stratified squamous epithelium
2. Lamina Propria
3. Fibromuscular layer
4. Adventitia

21

Are there glands in the vagina?

No. It is lubricated by mucous from the cervical glands.

22

Describe the histology of the clitoris?

Two tubes of erectile vascular tissue covered by a fibrocollagenous sheath covered by skin with a rich innervation and a thin epidermis.

23

What is the epithelium of the hymen?

Non keratinised stratified squamous epithelium.
