1

where is the obturator nerve

on lateral wall of pelvis with the ovary just medial to it

2

where is obturator fascia

overlies obturator internus and gives origin to levator ani

3

what is the innervation of levator ani

S3,4

4

what is puborectalis

the muscle that creates a sling around the rectal anal junction to aid rectal continence

5

what is pubovaginalis

closure of the vagina and support of genital organs

6

how big are ovaries

3 cm long

7

where are ovaries found

on lateral pelvic wall in ovarian fossa between the internal and external iliac vessels, medial to the obturator nerve and thin wall of the acetabulum

8

what might a central dislocation of the hip do

damage the ovaries

9

is the ovary intraperitoneal

yes, it is truly intraperitoneal due to absorption of the peritoneum into the ovary meaning it lies inside the peritoneal cavity

10

where is the ligament of ovary

in the broad ligament between the ovary and the uterus

11

what is the round ligament

the continuation of the ligament of the ovary (remnant of gubernaculum)
passes from the uterus, through the inguinal canal to the labia

12

where is the ovum released into

the peritoneal cavity, hence why ectopic pregnancies may occur in the peritoneal cavity

13

what structure is at risk during surgical procedures to the ovary

ureter due to it lying posteriorly

14

where might ovarian disease refer pain to

medial thigh dues to the obturator nerve lying laterally

15

what is the blood supply to the ovary

ovarian artery at L1,2 from aorta

16

what is the sympathetic supply to the ovary

T10/11

17

where is ovarian referred pain

peri umbilical region and medial thigh

18

what is the venous drainage of the ovaries

left to left renal vein, right to IVC

19

what is the lymph drainage of the ovary

para-aortic nodes

20

what forms the suspensory (infundibulopelvic ligament)

ovarian vessels passing down the posterior abdominal wall
they then enter the broad ligament

21

where does fertilisation occur

ampulla

22

where is the mesosalpinx (upper edge of the broad ligament)

between the fallopian tube and the ovary

23

what are the parts of the fallopian tube

fimbriae around the abdominal ostium
infundibulum
ampulla
isthmus
intramural part

24

what is the blood supply of the fallopian tube

anastomosis between the ovarian and uterine arteries

25

where is fallopian tube pain referred to

lower abdominal

26

how big is the uterus

8 cm long, pear shaped

27

what structures support the uterus

levator ani, perineal body, perineal membrane

28

where are the fascial thickenings that support the uterus

pass from the uterus to the sacrum, pubis and lateral pelvic walls

29

what is the tendinous arch of pelvic fascia

where the visceral and parietal fascia mess and fuse as the organs pierce the pelvic floor
runs from pubis to sacrum

30

what can weakness of the ligaments and muscles of the pelvic floor lead to

prolapse and urinary incontinence
