1

What completely envelops the uterine tubes?


Broad ligament

2

What are the ovaries suspended by?

Mesovarium

3

What are the ligaments that support the pelvis viscera made of?

Condensations of pelvic fascia

4

What is the role of the broad ligaments and what runs through them?

Broad ligaments are transverse mesenteries joining the uterus to the pelvic walls. They contains the uterine tubes and the uterine arteries.

5

What is the top part of the uterus called?


Fundus

6

What are the four parts of the fallopian tube?


Isthmus, Ampulla, Infundibulum, Fimbriae

7

What are the three ligaments that hold the cervix in place?


Pubocervical Ligament
Transverse (cardinal) Ligament
Uterosacral Ligament
These prevent the cervix from prolapsing

8

How is there a potential communication between the peritoneal cavity and the exterior via the reproductive passage?


The fallopian tubes open into the peritoneal cavity via the abdominal ostium of the uterine tube. This forms a connection between the exterior and the peritoneal cavity through the abdominal ostium of the uterine tube.

9

What are the two openings of the cervix?

Internal Os
External Os

10


What is the term for the opening of the fallopian tube into the uterus?


Uterine Ostium

11

Describe how the uterus changes in size throughout pregnancy.


The fundus rises up the abdomen. In the 10th month the fundus is lower than in the 9th month.

12

Describe the epithelial lining of the cervical canal.


Simple columnar epithelium - with goblet cells

13

Describe the epithelial lining of the vaginal surface of the cervix.






Non-keratinising stratified squamous epithelium - this is what is tested in the smear test

14

Describe the orientation of the axis of the cervix in relation to the axis of the vagina.


The axis of the cervix is at 90 degrees to the axis of the vagina

15

What is the normal arrangement of the uterine body, the cervix and the vagina?


Uterine body is anteflexed on the cervix
Cervix is anteverted on the vagina

16


How long is a normal vagina?

7-9 cm

17

Which fornix is important clinically?

Posterior fornix

18

What can be felt in the digital examination through the vagina?


Ischial spine
Ovaries
Uterine artery pulse
Cervix
Sacral Promontory

19

What are the main branches of the internal iliac artery that supply the pelvic viscera?


Superior Vesical Artery
Uterine Artery
Middle Rectal Artery

20

Which branches supply the walls of the pelvis?


Sacral, Gluteal and Obturator Branches

21

What artery supplies the perineum and the recto-anal region?


Pudendal Artery

22

Where is there an arterial anastomosis in the pelvic region?


Ovarian artery and the uterine artery both supply the ovaries and they anastomose.

23

What are the two divisions of the uterine artery?


Ascending Branch - supplies the uterus and ovary (along with the ovarian artery)
Descending Branch - Vaginal Artery (equivalent of inferior vesical in men) - supplies the vagina

24

Where are eggs from the ovary initially released into?


Into the peritoneal cavity because the ovary is on the posterior surface of the broad ligament

25

How is the bulbospongiosus different in women?













It splits into two around the vestibule of the vagina

26

What makes up the body and glans of the clitoris?

Body - corpora cavernosae
Glans - corpus spongiosum

27

Describe the arrangement of sphincters in the deep perineal pouch.


Part of the pelvic floor muscles form compressor urethrae (compresses the urethra)
Parts of the fibres from here combine with the external urethral sphincter to for sphincter urethrovaginalis.
It wraps around the urethra and keeps it closed.

28


What is the collective name for female external genitalia?


Vulva

29

What gland in women is the equivalent of the prostate in men?

Skene's gland (Paraurethral gland)
REMEMBER: nerve supply is the same in women

30

Which lymph nodes do the pelvic organs drain to?


External and internal iliac lymph nodes
