1

Are there glands in the mucosa of the vagina?

No

2

What types of cells detect foreign pathogens in the vagina?

dendritic cells

3

What part of the female reproductive tract provides secretions for lubrication during intercourse?

Cervical mucosa

4

The epithelial cells of the vaginal wall releases large amounts of ___?

Glycogen

5

Why do the epithelial cells of the vaginal wall secrete large amounts of glycogen?

It is metabolised by resident bacteria (lactobacillus), producing lactic acid & H2O2 - decreasing the pH (acidic), making it toxic to foreign pathogens

6

What does the adventitia of the vagina connect to?

Surrounding structures such as the urethra and urinary bladder

7

What layers exist in the muscularis of the vagina?

Outer ongitudinal and inner circular layer

8

What is the vaginas blood supply?

Internal vaginal artery branching off the uterine artery

9

What is the name of the portion of the cervix that projects into the vagina?

Ectocervix

10

What is the opening of the ectocervix called?

External os

11

What is the other name for the cervical canal?

Endocervix

12

When is the cervix relaxed and cervical mucous thin and at a ten-fold increase in secretion? What hormone causes this?

Ovulation, Oestrogen

13

What hormone causes thick secretions and a firm cervix?

Progesterone

14

The transformational zone separates the endocervix and ectocervix. What type of epithelium are these structures?

Endo: Simple columnar

Ecto: Stratified keratinised squamous

15

What is the pap smear and what does it entail?

A cytodiagnostic test for the early detection of cervical cancer. Scrape surface epithelial cells from transitional zone of cervix mucosa, spread on glass slide and stain.

16

What is the name of the stain used for a pap smear?

Papanicolaou

17

What is this?

An abnormal pap smear

18

What is this?

A normal pap smear

19

Where is a fertilised ovum implanted?

Uterus

20

What is the blood source for the uterus?

Internal illiac branches to uterine artery that also supplies the cervix and vagina

21

What are the 3 layers of the uterus? Describe them.

Perimetrium: Outer serous membrane

Myometrium: Smooth muscle (x3/4), thick, contracts during delivery. Cervix: more rigid and less contractile than rest of uterus

Endometrium: Mucous membrane, simple tubular glands, leukocytes (7%).

22

What layer of the endometrium is hormone responsive?

Stratum functionalis

23

What is the epithelium of the uterus?

Simple columnar

24

What are the two outermost layers of the overy?

Visceral peritoneum then tunica albuginea

25

Is the cortex or the medulla of the ovary the functional part for reproduction?

Cortex

26

What is the medulla of the ovary composed of?

CT, blood vessels, glands, nerves and lymphatics

27

What is the rate of pulsatile release of GnRH during follicular phase in a female?

Every 60-90 minutes

28

How many viable gametes does a female produce from 1 primary cell?

 

1

29

When do germ cells arise and colonise gonadal ridges becoming oogonia?

Week 5-6

30

Until what month of gestation are oogonia multiplying via mitosis? How many eggs present at this stage?

5th month, 7 million eggs1
