16
Q

muscular support of uterus (2)

A
  • levator ani and its fascia

- perineal body (in the perineum)

17
Q

endopelvis fascia (bands of CT) support of the uterus

A
  • transverse cervical (cardinal) lig (upper vagina + cervix to lateral pelvic wall. contains uterine and vaginal vessels
  • pubocervical ligs (cervix to pubic bones. 2 bands)
  • sacrocervical ligaments (cervix + upper vagina to lower sacrum). travels in the uterosacral fold
18
Q

broad lig + assoc structure supporting uterus

A
  • broad ligament (like a curtain covering the fallopian tubes)
  • round ligament of the uterus
  • ovarian ligament (ligament of the ovary)
  • suspensory ligament of the ovary
19
Q

what is the uterosacral fold

A

fold in back wall of cervix made by rectum being there and pushing the sacrocervical lig around (sacrocervical ligs surround the rectum)

20
Q

clinical significance of uterosacral fold

A

if any support of uterus (like this one) becomes lax, cervix can descend in the vagina or vestibule

21
Q

parts of the Fallopian tube (uterine tube)

A
  • fimbriae
  • infundibulum
  • ampulla (wide, site of fertilization)
  • isthmus (narrow near uterus)
  • intramural (part of uterine wall)
22
Q

Fallopian tube relates to what ligament

A

lies in the upper boarder of the broad ligament

23
Q

some sites of ectopic pregnancies

A
  • abdomen (fimbriae didn’t catch the egg)
  • fallopian tube
  • cervix
24
Q

most common site of ectopic pregnancies

A

Fallopian tube

25
Q

ligament of the ovary (ovarian ligament) function and position

A
  • connect uterus to ovary
  • lies below Fallopian tube, a bit posteriorly
  • is posterior to the round ligament of the uterus
26
Q

suspensory ligament of the ovary position and function

A
  • connects the ovary to the pelvic wall
  • contains ovarian a. and v
  • passes below the fimbriae
27
Q

broad ligament is what

A

curtain covering the uterus and fallopian tube anteriorly and posteriorly
IS MADE OF PERITONEUM

28
Q

round ligament of the uterus is what + POSITION**

A
  • originates at the uterine horns (meaning near the tubes)
  • lies below the Fallopian tube, a bit anteriorly
  • is anterior to the ovarian ligament
  • exits the pelvis at the deep inguinal ring
  • passes through the inguinal canal
  • reaches the labia majora
29
Q

mesometrium def

A

sheet, fold of peritoneum (mesentery) formed by the portion of the broad lig that is below the ovarian lig and round lig of the uterus anteriorly and posteriorly

30
Q

mesosalpinx def

A

sheet, fold of peritoneum (mesentery) formed by the portion of the broad ligament that extends from the Fallopian tube (uterine tube) to the round ligament of the uterus and ovarian ligamen anteriorly and posteriorly

31
Q

shape of broad ligament sagittal section

A

diamond shape

  • sup = fall tube
  • inf = wall, floor
  • ant = round lig of the uterus
  • post = ovarian lig
32
Q

mesovarium def

A

sheet, fold of peritoneum (mesentery) formed by the portion of the broad ligament that extends from the center of the diamond of the broad lig (in sagittal) to the ovary, superiorly and inferiorly (overlaps the mesosalpinx and mesometrium a bit but not really bc is only the broad lig parts that are closest to the ovary)

33
Q

blood supply to the ovaries, uterus, cervix, vagina

A
  • ovarian a (comes from aorta and travels in suspensory lig of ovary to the ovary)
  • uterine a (from internal iliac a, travels in transverse cervical (cardinal) ligaments, gives a vaginal branch travelling along uterus and cervix down to vagina)
  • vaginal a (from internal iliac a) travels in transverse cervical (cardinal) ligaments
  • vaginal branch of uterine a
  • anastomoses between vaginal branch of uterine a + vaginal a
  • veins follow back*
34
Q

equivalent of the round lig of the uterus in the male

A

testicular a coming off aorta (and testicular v going back to renal v) and going down to the scrotum via inguinal canal

35
Q

vesicouterine pouch def

A

peritoneal reflection in the female between superior bladder and anterior uterus over fundus and down posterior uterus
*bc in reality the uterus is falling to the front on top of the bladder)

36
Q

rectouterine pouch or pouch of Douglas

A

peritoneal reflection in the female between posterior fornix of the vagina and anterior surface of middle third of the rectum

37
Q

peritoneal reflections in the female genital viscera

A
  • anterior abd wall
  • sup to pubic bone
  • sup surface of bladder
  • vesicouterine pouch
  • over fundus until posterior bottom uterus
  • rectouterine pouch
  • anterior and lat surfaces of superior third of the rectum
  • posterior pelvic wall back to sigmoid colon to form the sigmoid mesocolon (mesentery holding the sigmoid colon) which is in the abd cavity**
38
Q

rectovesical pouch def

A

peritoneal reflection in the male covering the back of the bladder, top of seminal vesicles and then anterior surface of middle third of rectum)

39
Q

peritoneal reflections in the male

A
  • anterior abd wall
  • sup to pubic bone
  • sup surface of bladder
  • post surface of bladder
  • top of superior end of the seminal vesicles
  • rectovesical pouch
  • ant and lat surfaces of the superior third of the rectum
  • post pelvic wall and posterior to sigmoid colon to form the sigmoid mesocolon (mesentery of the sigmoid colon) which is in the abd cavity**
