Flashcards in Cobine: Female Pelvis Deck (54):
1

Structures covered by peritoneum in the female pelvis

rectum
ovary/ovarian vessels
bladder
uterus/round lig of uterus
ureter

2

The peritoneum continues from the anterior abdominal wall, curves at the level of the (blank), covers the (blank) surface of the bladder to the (blank) of the uterus, forming the (blank) pouch; then covers the fundus/body of the uterus, extends over the (blank) of the vagina, extends from the uterus to the rectum forming the (blank) pouch, then covers the anterior/lateral parts of the superior rectum and the lateral sides of the middle rectum before becoming sigmoid (blank) at S3

pubic bone; superior; isthmus; vesicouterine; fornix; rectouterine; mesocolon

3

(blank) fossa on each side of the bladder; (blank) fossa on each side of the rectum; separated by the (blank) of the uterus

4

What is contained in the broad ligament of the uterus?

1. uterine tubes
2. ovaries and their ligaments
3. round ligament of the uterus

5

Deep recesses where fluid can accumulate in event of an infection; this pouch can collect blood or puss, is posterior to the fornix of the vagina

vesicouterine and rectouterine (Pouch of Douglas) pouches; Pouch of Douglas

6

an inflammation of the peritoneum, may result from infection (e.g. from rupture of a hollow organ) or from a non-infectious process. If left untreated, sepsis.

peritonitis

7

extraction of fluid from the Pouch of Douglas via the posterior fornix of the vagina

culdocentesis

8

small incision, endoscope inserted for viewing.

colpotomy

9

T/F: pelvic peritonitis is usually fatal

True

10

What passes over the ureter in the female on its course to the posterior bladder? This is something to keep in mind when performing a hyst.

uterine artery

11

The apex of the bladder is in direct relation to the (blank). The bladder fundus is in direct relation to the (blank).

fundus of the uterus; anterior wall of the vagina

12

When empty, the bladder is in the (blank) pelvis. When full, the bladder is in the (blank) pelvis.

lesser pelvis; greater pelvis

13

What is significant about the retropubic space?

allows distensibility of the bladder

14

What is significant about the lateral ligaments (pubovesical) of the bladder and the tendinous arch of pelvic fascia?

keep the bladder in place

15

What composes bladder walls?
Utereric orifices and the internal urethral orifice are at the angles of the (blank) bladder
Ureteric orifices are encircled by loops of (blank) that tighten as the bladder contracts to prevent the reflux of urine into the ureter

detrusor muscle; trigone; detrusor muscle

16

Blood supply to:
1. anterosuperior bladder
2. fundus and neck
3. other

1. superior vesical arteries
2. vaginal arteries (inferior vesical in males)
3. obturator and inf. gluteal arteries

17

Venous drainage in female bladder corresponds to arteries. (blank) plexus receives blood from the dorsal vein of the clitoris, and this plexus communicates with the (blank) plexus.

vesical venous plexus; vaginal

18

double layer of peritoneum extending from the sides of the uterus to the lateral walls and floor of the pelvis keeping the uterus in place

broad ligament of the uterus

19

3 parts of the broad ligament
1. contains the uterine tube
2. contains the ovary
3. acts as the mesentery for the uterus

1. mesoalpinx
2. mesovarium
3. mesometrium

20

Where the broad ligament is prolonged superiorly over the ovarian vessles; superolateral to the ovary

suspensory ligament of the ovary

21

lies anteroinferior to the uterotubal junction, courses to deep inguinal canal, passes through the inguinal canal and terminates at the labium majus

round ligament of the uterus

22

What are the ovarian ligament and round ligament of the uterus vestiges of?

ovarian gubernaculum

23

extend from the supravaginal part of the cervix and lateral vaginal fornices to the lateral walls of the pelvis (contains uterine artery and vein)

transverse cervical ligaments (cardinal ligament)

24

condensations of the pelvic fascia that extend from the cervix to the posterolateral pelvic walls

uterosacral ligament

25

The ovary is suspended by peritoneal folds: from the posterosuperior aspect of the broad ligament by the (blank) and from the lateral pelvic walls by the (blank)

mesovarium; suspensory ligaments of the ovary

26

(blank) contains ovarian vessels, lymphatics, and nerves which run within the suspensory ligament of the ovary contained within it

mesovarium

27

When an oocyte is expelled, it passes into the (blank). It is trapped by the fimbriae (finger-like projections) of the (blank) of the uterine tube and swept up into the ampulla for possible fertilization

peritoneal cavity; infundibulum

28

Two parts of the uterus - what demarcates the two parts?
Two surfaces of the uterus

body (superior 2/3) and cervix (narror inferior 1/3); isthmus; vesical and intestinal

29

The body of the uterus lies on the (blank); the cervix lies between these two things

bladder; bladder and rectum

30

What separates the supravaginal part of the cervix from the rectum?

Pouch of Douglas

31

Two parts of the cervix

supravaginal (between isthmus and vagina) and vaginal

32

Narrow space surrounding the external os of the uterus (cervix); has anterior, posterior, and lateral parts

vaginal fornix

33

Three parts of uterine wall
1. serosal layer
2. middle coat of smooth muscle, main branches of blood vessels, dilates the cervical os during childbirth, producing cramping
3. inner mucous coat that is shed during menstruation, location of blastocyst implantation

1. perimetrium
2. myometrium
3. endometrium

34

T/F:
The cervix is mostly fibrous vs. the muscular uterine body.

childbirth
aging
lack of estrogen after menopause
pressure on pelvic muscles

39

1st degree prolapse vs. 2nd degree vs. 3rd degree
