1

what are the ovaries?

female gonads

2

where do gonads develop in both males and females?

mesonephric ridge and descend through the abdomen

3

how is the descend of the ovaries different from the testes (both gonads)

ovaries stop in the abdomen
testes descend into the scrotum
(both guided by gubernaculum)

4

what are the ovaries? (attachment)

paired, oval organs attached to the posterior surface of the broad ligament of the uterus by the mesovarium

5

what is the mesovarium?

a (double) fold of peritoneum, continuous with the outer surface of the ovaries

6

what is the function of the mesovarium?

Neurovascular structures enter the hilum of the ovary via the mesovarium

7

what are the main functions of the ovaries?

To produce oocytes
To produce the sex steroid hormones oestrogen and progesterone

8

when are oocytes produced?

in preparation for fertilisation
(oocytes = female gametes)

9

when are oestrogen and progesterone produced from the ovaries?

in response to FSH and LH (pituitary gonadotrophins)

10

what are the components to the ovaries? (superficial to deep)

3 parts:
surface
cortex
medulla

11

what is the surface of the ovary formed by?

simple cuboidal epithelium, known as germinal epithelium

12

what is the cortex of the ovary comprised of?

The cortex (outer part) of the ovary is largely comprised of a connective tissue stroma

13

function of the CT stroma within the cortex of the ovary?

It supports thousands of follicles

14

what does each primordial follicle contain?

contains an oocyte surrounded by a single layer of follicular cells

15

what is the medulla of the ovary composed of?

The medulla (inner part) is composed of supporting stroma

16

what does the supporting stroma of the medulla contain?

contains a rich neurovascular network which enters the hilum of ovary from the mesovarium

17

what are the ligaments which attach to the ovaries?

Suspensory ligament of ovary
ligament of ovary

18

what is the suspensory ligament of ovary?

fold of peritoneum extending from the mesovarium to the pelvic wall

19

what does the suspensory ligament of ovary contain?

neurovascular structures

20

where does ligament of ovary extend from? to?

extends from the ovary to the fundus of the uterus

21

where does the ligament of ovary continue from the uterus to?

from the uterus to the connective tissue of the labium majus

22

what does the ligament of ovary continue from the uterus to the CT of labium majus as?

as the round ligament of uterus

23

when does ligament of ovary become the round ligament of uterus?

at the fundus of the uterus
(prior - from ovary: ligament of ovary, post: to labia majora as round ligament of uterus)

24

ovaries blood supply?

ovarian arteries

25

where do ovarian arteries arise?

directly from abdominal aorta
below renal arteries

26

venous drainage of ovaries?

ovarian veins

27

where do ovarian veins drain into?

R ovarian vein - IVC
L ovarian vein - left renal vein

28

lymphatic drainage of ovarian veins?

para-aortic nodes

29

where do nerve supply to ovaries run? enter?

via the suspensory ligament of the ovary with the vasculature, to enter the ovary at the hilum

30

where do ovaries receive innervation from?

The ovaries receive sympathetic and parasympathetic nerve fibres from the ovarian (sympathetic) and uterine (pelvic) plexuses (parasympathetic)
