the bladder is ___-______ to the pubic bone

what is the space in between?

postero-superior

THe ureter is very close to which artery in the female?

uterine artery - crosses over it

The trigone of the bladder differs how from the rest of the bladder?

14

the base of the bladder is facing

posteriorly

15

the neck of the bladder surrounds...

the urethral outlet

16

The neck is anchored to the pelvic wall via what?

pubovesical lig.

The lateral ligaments are condensations of fascia around the vesical artery

17

what produces the sperm in the testes?

seminiferous tubules with interstitial tissue in between

18

the seminiferous tubules with interstitial tissue in between are surrounded by what capsule?

Tunica albuginea - connective tissue capsule

19

Surrounding the Tunica albuginea is the..?

peritoneum - called the tunica vaginalis

20

If there is a continuation f the peritoneum with the adbo cavity there is an increased risk of _____

herniation

21

What is the epididymus?

23

vas deferens runs through the _____ canal

inguinal canal

vas deferens crosses what at the pelvic inlet?

external iliac vessels

25

The seminal vesicles secretions are simply adding what to the semen?

volume

26

Where is the prostate gland situated?

neck of the bladder above
levator ani and urogenital diaphragm below

27

pubo-prostaticus is the male equivalent of what?

pubo-vaginalis

28

What is in the urethral crest?

bump - two gutters on eaither side called prostatic sinuses.

The ejaculatory ducts open into the urethral crest (final common pathway of vas and seminal vesicles)

29

What does the bulbouretral gland pass through to enter the penile-urethra?

peritoneal membrane -

30

What does the prostate gland relate to posteriorly?

the rectum

31

The middle lobe of the prostate lies in the urethra, what is its significance?

its the part that enlarges in benign prostatic hypertrophy

32

What is the approx size of the uterus?

8cm/5cm/3cm

33

The uterus is nromally positioned..

anti-verted (bend forwards on the vagina) and anti-flexed (flexed forward on itself)

but not always

34

true

35

The part of the body of the uterus that narrows to become the cervix is the...

Isthmus

36

What are the delineations of the cervix?

twowards the vagina: external uterine opening

towards the isthmus: internal uterine opening

37

the canal of the cervix is how long?

2-3cm in length

38

Which part of the uterus is fixed? (the ligaments are a really important, learn them)

the neck - by fascial condensations (utero-sacral lig. and lateral cervical)

39

Where does the broad ligament go from?

from side walls of uterus, uterine tubes are in the superior aspect

to

side walls of pelvis

40

how long are the uterine tubes? where are they?

10-14cm in length - in the superior part of the broad ligament

41

What is the name of the part of the uterine tube that is in the uterus?

intramural

42

What are the sections of the uterine tube AFTER the itramural part?

isthmus - straight and narrow

ampulla

infundibulum

43

The ovary is stuck on the back of the ____ ligament

broad ligament

but hangs off with its own little mesentery

44

The ovary sits on the side wall of the pelvis in a shallow fossa, between the ...

internal and external iliac vessels

where they divide

45

what attaches the ovary to the upper and angle (shoulder) of the uterus?

ovarian ligament - continuous with the round ligament

46

what supplies the ovary?

ovarian artery - one of the paired branches coming off the aorta

then gives off a branch to the uterine tube - this anastomoses with the uterine artery from the side wall of the pelvis (crosses the ureter in females remember!)
