Flashcards in female pelvic viscera Deck (69):
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

31

where is the broad ligament

uterus to lateral pelvic wall

32

where is the round ligament

passes in the broad ligament from the uterus to the deep inguinal ring and down the inguinal canal to fuse with the labia

33

what is the function of the broad and round ligaments

hold the uterus anteverted and anteflexed

34

what is the posterior fornix related to

pouch of douglas aka rectouterine pouch

35

what are the fornices

where the cervix pushes into the vagina

36

how can the posterior fornix be used clinically

to access the peritoneal cavity

37

how long is the cylinder of the cervix

2.5 cm long with vaginal and supra vaginal parts

38

what is the external os

where the vaginal part of the cervix opens into the vagina

39

what is the internal os

narrowing of the cervix at the isthmus of the uterus

40

describe the position of the uterine cervix in relation to the vagina

anteverted

41

describe the position of the cervix and body of the uterus

anteflexed

42

what can retoversion and retroflexion cause

back ache and difficulty in conceiving

43

what is the blood supply of the uterus and vagina

uterine and vaginal anastomoses plus vesicle artery involvement

44

how long is the vagina

1o cm

45

where is the ureter in relation to the pelvic organs

inferior to the uterine artery and adjacent to the lateral fornices

46

what sphincter surrounds the vagina

the urethral or urethrovaginal sphincter which is derived from levator ani

47

what is the blood supply to the vagina

uterine artery, superior vesicle, vaginal, internal, pudendal artery
all from the internal iliac artery

48

what is the blood supply to the urethra

vaginal and internal pudendal

49

what is the external pudendal artery derived from

femoral

50

what does the urethra pass through

deep perineal pouch with external sphincter and perineal membrane

51

what is the lymph drainage of the bladder and urethra

external and internal iliac nodes

52

what is the lymph drainage of the ovary

para aortic

53

what is the lymph drainage of the uterus and proximal vagina

internal iliac nodes

54

what is the lymph drainage of the uterine tube

para aortic and superficial inguinal

55

what is the lymph drainage of the distal vagina and urethra

deep and superficial inguinal nodes

56

what is the value of the sympathetic pre aortic plexus

T10 -T11 from sympathetic trunk

57

what is the value of the pelvic plexus

pelvic splanchnics- S2-4

58

what is the value of the internal pudendal nerve

S2-4

59

what forms the left and right pelvic plexuses

superior hypogastric plexus which is T12 - L2

60

what is the nerve supply of the ovary

pre aortic sympathetics from T10 and 11
pain is periumbilical

61

where is pain referred from the uterus

suprapubic - t12 -L1

62

where is pain from the cervix and proximal vagina felt

deep in the pelvis

63

what does the gubernaculum form in the female

ligament of ovary and round ligament

64

what is the nerve value of the pre aortic sympathetic plexus (supplies the ovary)

T10 - L 2 (boosted by lumbar splanchnics)

65

what is the nerve supply of the superior hypogastric plexus

T12 - L2

66

what is the sympathetic supply of the ovary

pre aortic sympathetics from T10- 11
pain is peri umbilical

67

why is uterine pain suprapubic

passes via pelvic plexus- mainly t12-L1

68

what is the pain line

structures inferior to the peritoneum is via the p'sympathetic pelvic splanchnics and so felt deep in the pelvis
i.e. abdominal viscera (cervix) where as vagina is somatic due to it not being an internal organ

69

what part of the vagina is supplied by the internal pudendal

distal (somatic)
