Flashcards in 155, 157, 158. Anatomy of the female reproductive system Deck (12):
1

What shape are the gonads and what size are they in the young?

Almond; 3cm

2

For the OVARIES, name the:
a) arterial supply
b) venous drainage
c) lymphatic drainage

a) Ovarian artery - from aorta at level of renal artery
b) Ovarian vein - drains into IVC on right, and into left renal vein on the left
c) Aortic lymph nodes - at level of renal vessels

3

List the 3 main ligaments with relation to the ovaries

Broad ligament - ovaries attach to it's posterior wall "mesovarium" (drapes over uterus and uterine tubes)

Ovarian ligament - attaches ovary to uterus

Suspensory ligament - carries ovarian artery and vein
- attaches from lateral wall of pelvis to ovary

4

Name the two peritoneal reflections

Rectouterine pouch
Uterovesical pouch

5

How long are the uterine tubes and what is their anatomical relation to the ovaries?

approx 13cm long
Do NOT attach to ovaries

6

Name the parts of the uterine tube and what is significant about each area

Infundibulum - funnel shaped opening into peritoneal cavity, fringed by finger-like FIMBRIAE

Ampulla - middle section - where fertilisation occurs

Isthmus - narrowest part of uterine tube, connected to uterine wall

7

Describe the shape and size of the uterus

Inverted pear shape
Flattened from front to back
Where foetus grows
7-8cm long, 5cm wide, 2.5cm thick in resting state (may vary in aged)

8

Name the different parts of the uterus (4)

1. Body
2. Cervix "neck" with external and internal os
3. Fundus - rounded part which projects above uterine tubes
4. Isthmus - narrowing between body and cervix

9

Define the terms in relation to the uterus' positioning:
a) antiflexion
b) antiversion

a) Body of uterus is bent forwards on the cervix
b) Whole uterus is bent forward at a right angle to the vagina

10

What % of females show retroflexion and retroversion?

20%

11

For the UTERUS, what is the:
a) blood supply
b) venous drainage
c) lymphatic drainage

a) Uterine artery - a branch of the internal iliac artery
b) Uterine vein - drains into internal iliac vein
c) Para-aortic lymph nodes - drains body
Internal iliac nodes - drains cervix

12

What is the clinical significance of the female duct system opening to the peritoneal cavity?

Females have more risk of infections spreading in and up from the exterior female gamete is spread to peritoneal cavity
