What strucuters, in male and female, cross the ureter above it's entry into the bladder?
male: vas deferens
female: uterine artery
the bladder is ___-______ to the pubic bone
what is the space in between?
THe ureter is very close to which artery in the female?

what produces the sperm in the testes?
seminiferous tubules with interstitial tissue in between
the seminiferous tubules with interstitial tissue in between are surrounded by what capsule?
Tunica albuginea - connective tissue capsule
Surrounding the Tunica albuginea is the..?
peritoneum - called the tunica vaginalis

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)

peritoneal membrane -
What does the prostate gland relate to posteriorly?
The middle lobe of the prostate lies in the urethra, what is its significance?
its the part that enlarges in benign prostatic hypertrophy
What is the approx size of the uterus?
The uterus is nromally positioned..
anti-verted (bend forwards on the vagina) and anti-flexed (flexed forward on itself)
but not always
true or False
The uterus is slightly flattened in the anterior/posterior direction
The part of the body of the uterus that narrows to become the cervix is the...
What are the delineations of the cervix?
twowards the vagina: external uterine opening
towards the isthmus: internal uterine opening
the canal of the cervix is how long?
2-3cm in length
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)
Where does the broad ligament go from?
from side walls of uterus, uterine tubes are in the superior aspect
side walls of pelvis
how long are the uterine tubes? where are they?
10-14cm in length - in the superior part of the broad ligament
What is the name of the part of the uterine tube that is in the uterus?
What are the sections of the uterine tube AFTER the itramural part?
isthmus - straight and narrow
The ovary is stuck on the back of the ____ ligament
but hangs off with its own little mesentery
The ovary sits on the side wall of the pelvis in a shallow fossa, between the ...
internal and external iliac vessels
where they divide
what attaches the ovary to the upper and angle (shoulder) of the uterus?
ovarian ligament - continuous with the round ligament
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!)
Which wall of the vagina is shorter?
anterior - 10cm
posterior - 12
what space is in the superior part of the vagina?
fornix - circular recess around the lowermost portion of the cervix
whaat do slackenings of the ligamentous supports of the vagina lead to ?
prolapse - things moving where they shouldn't
uterus usually pushed down into the vagina
there can also be encroachment on the vagina from the..
bladder or rectum
the rectum loses what, as comapred to the sigmoid colon?
tenia coli - just one longitudinal muscle band
The upper 1/3 has no _____ but ______covering it front and side
the middle 1/3 is truly __________
lower 1/3 is a ___pelvic viscus - beneath the _________
The upper 1/3 has no mesentery but peritoneum covering it front and side
the middle 1/3 is truly retroperitoneal
lower 1/3 is a true pelvic viscus - beneeath the peritoneum
rectum has _ ____ curves, covexed to the left
rectum has 3 lateral curves, covexed to the left
creates 3 shelves "of heuston"
the ampulla of the rectum is the
dilated part inferiorly
What supplies the rectum?
after supplying colon, becomes the superior rectal artery
also reinforced by a middle rectal artery from the side wall of pelvis (from internal iliac)
