Female Pelvis
retroflextion
bending backward
fallopian tubes
coiled, muscular, extend from ovaries to uterus
four subdivisions of fallopian tubes
interstitial, isthmus, ampulla, infundibulum
anteverted uterus
uterus is tilted or bent forward 90 degree towards cervix
bicornuate uterus
uterus with two horns
Arcuate uterus
-NO obstetric issues. indentation of fundus, normal variant.
length of ovaries
2.5 cm to 5 cm AP .6 to 2.2 cm trans 1.5 to 3 cm
fallopian tube length
7 to 12 cm
length of uterus
8 cm (nilluparous), 3 cm (AP), trans (5.5 cm)
Didelphys uterus
Complete duplication of the uterus, cervix, and vagina
Late proliferative which hormones stop
FSH goes down
volume of ovaries
L x AP x W x 0.523
secretory phase hormones
LH
Levoversion
Left lateral deviation
unicornate of uterus
Results if one of the paramesonephric ducts fails to develop
Anteflexed uterus
When the bladder is empty and the cervix and vagina form a 90-degree angle, and the uterine body and fundus are bent at a great anterior angle until the fundus is pointing inferiorly and resting on the cervix
increased resistance index
abnormal flow during pregnancy, increases small percentages of complications notching increased risk of pregnancy loss. greater than .58 RI abnormal in pregancy doppler.
reflections of uterus form
anterior and posterior cul de sac
Pelvic recesses
anterior cul de sac and posterior cul de sac (most dependent space in abdominopelvic cavity)
anteflexion
bending forward
retroflexed
bent backward
uterine ligaments (attach to inferior ovary)
broad (duperior lateral vessels and nerves sometimes seen in sonography), round, and cardinal, sacrouterine (suspensory) sacroiliac, sacrosciatic, sacrococcygeal, pubic (osseous)
Septate uterus
congenital malformation of the uterus that results in a single septum that separates two endometrial cavities.
Ovaries
ellipsoid shape, in ovarian fossa (fossa of waldeyer). bounded laterally by internal iliac artery and the ureter. the medial boundery is the uterus.
Uterus wall layers
endometrium, myometrium, perimetrium/ serosa
retroverted uterus (before uterine suspension)
entire uterus - body and cervix- tilted backwards
menses hormones
estrogen, FSH
interstitial uterus appears as
fine echogenic line from endometrial canal through myometrium to the cornua of the uterus
4 regions of the uterus
fundus, body, isthmus, cervix
ovarian vascular supple
gonadal arteries and veins, branches of uterine artery and vein rise to ovarian branches at level of cornu.
hypoplasia
incomplete development
Ovaries
lie on posterior surface of broad ligament, peritoneal, mobile with adnexa (joins)
medianus
middle
infundibulum of uterus
most lateral of the tube and opens to peritoneum and fimbria
isthmus of uterus
narrowed inferior region
female pelvis
pelvic cavity is the caudal (tail) portion of the abdominopelvic cavity. extends from iliac crest to pelvic diaphragm (peritoneal). contains urinary bladder, genetial tract, ovaries, and pelvic colon.
Vagina
posterior to bladder and urethra. anterior to rectum, extends from uterine to external genitalia, uterine cervix protrudes into anterior vaginal wall.
Posterior cul-de-sac
pouch of douglas, rectouterine space.
uterus is
retroperitoneal, covered by peritoneum
Dextroversion
right lateral deviation
two ligaments not true, but folds in peritoneum
suspensory ligament arises from pelvic wall and contains vessels within broad. broad ligament is double folds of peritoneum it fans over adnexa and divides into front and back pelvis. it does very little to support the uterus.
retroverted uterus
the entire uterus including the body and the cervix are tilted backwards; contrasts with anteverted, anteflexed, or mid-position uterus
resistance in placenta to mothers blood flow then
the uterine artery becomes notched, flow reversal outcome poor. about 5% woman have notched artery at 23 weeks, not all have problems. increase high blood pressure 3-6 times, small, problems death of fetus 2 to 3 times. if normal the chances of above are reduced by similar margin.
retroversion
tilted backward
Retroversion with retroflexion
tipped backward and posterior
anterversion of uterus
tipped forward
uterine artery
travels superiorly from cervix, lateral to uterus in the broad ligament, at the junction of uterus and fallopian tubes. joins ovarian art, arcuate, radial, which supply myo and endo, straight, anf spiral supply endo. venous channels of pelvis are similar in travek,,
internal iliac artery (hypogastric)
uterine arteries are branches of these.
uterus vascular supply
uterine artery and vein, internal iliac artery and vein, arcuate arteries and veins
Anterior cul-de-sac
utero-vesicular space, space of retzius
anteverted uterus
uterus is tilted or bent forward
ampulla of uterus
widest and longest part fertilization of the oocyte usually occurs here
