vessels come in and out of the ovary.
What happens during ovulation?
The follicle ruptures
Oocyte is released from the ovary.

Why is a sharp pain felt at ovulation?
This is due to the rupture of the capsule of the ovary due to the oocyte being released.
Why do nuns tend to get ovarian cancer?
This is because they don’t have children or sex, so they undergo more ovulations.
- In ovulation, the follicle ruptures through the capsule of the ovary.
- This means that there is an increased rate of mitosis which may result in metaplasia etc.
What is an ovarian cyst and why should you not burst it?
It is an epithelial lying fluid filled cavity.
- It shouldn’t be burst as the fluid in the cyst may be full of cancer cells and these can spill out if burst.
How might a person with an ovarian cyst present?
- mass effect - compresses adjacent structures.
- Bulky ovary can twist - ovarian torsion.
Where is the fundus?
It is the top of the uterus.
Where is the cervix and what is it like?

What does the round ligament do?
- It tethers the uterus to the pelvis.
- As the uterus grows, it pulls on the ligament resulting in pain and discomfort.

What is the infundibulum?
It is the funnel shaped part.
it is there to funnel the egg into the tube.
What are fimbriae?
They are projections on the end.
- They are motile
- They are involved in attracting the egg released from the ovary into the tube.
How is the structure of the ampulla related to function?
- It is highly folded surface
- –provides a large SA and a cosy environment for the egg and sperm.
- It has cilia, which move the egg down.
- There are also peg cells, which release nutrients for egg and sperm function.
Describe the differences in peritoneum between men and women?
- The uterine tubes in women open into the peritoneal cavity.
- In men the peritoneum is continuous.
Where is the viscicouterine recess?
-This is between the bladder and uterus.
