The Female Pelvis Flashcards
female reproduction organs function (3)
production of sex hormones
production of ova
serves to protect and support developing embryos
uterus haas how many regions
5
uterine wall composed of ___ layers
3
normal adult size of uterus
7-8cm in length
parts of uterus
cervix
isthmus
body
cornua
fundus
body of uterus AKA
corpus
endocervical canal length
2-3cm
internal os
superior margin of cervix
level of isthmus
external os
inferior margin of cervix
canal opens into vagina
3 layers of uterine wall
endometrium: inner, highly vascular, composed of epithelial and glandular cells
myometrium: middler, thickest, muscle
perimetrium (serosa): thin outer, serous peritoneum
uterine location:
____ to rectum, ____ to peritoneum, ____ to ovaries, ______ to bladder (full), _____ to bladder (empty)
anterior
inferior
medial
posterior
superior
anteverted uterus
most common
anterior tilt
forms 90 degree angle with cervix and vagina
anteflexed uterus
anterior flexure of the body and fundus of the uterus
retroverted
body and fundus tilt posterior
cervix is more straight on to vagina
retroflexed uterus
body and fundus flex posteriorly
more difficult to assess sonographically (running parallel to beam/further away)
uterus didelphys
2 of everything
uterus bicornis bicollis
2 uterus/cervix
1 vagina
uterus bicornis unicolis
2 uterus
1 cervix/vagina
uterus subseptus
separation/wall in uterine canal
can make it harder to have viable preganancy
uterus unicornis
smaller uterus, thinner muscle, 1 fallopian tube/ovary
fallopian tubes AKA
uterine tubes/oviducts
fallopian tube diameter
3mm or less
segments of fallopian tubes
interstitial or intramural
isthmus
ampulla
infundibulum
interstitial/intramural segment of fallopian tube
narrowest part located within uterine cornua
isthmus segment of fallopian tube
adjacent to uterine wall
short, straight and narrow
ampulla segment of fallopian tube
longest section
widens laterally
usual area of fertilization
infundibulum segment of fallopian tube
funnel shaped lateral portion
contains fimbria
fimbria
finger-like projections that sweep ovum towards the tube
located in infundibulum segment
ellipsoid meaning
almond shaped (ovaries)
ovaries produce ___ and ____
estrogen
progesterone
ovarian size post puberty
length: 3cm
width: 2cm
and to post (AP): 1 cm
ovaries are located in the
true pelvis
adnexa
ovaries are typically ____ to uterus, ____ to broad ligament, ____ to ureter, _____ to internal iliac artery, and ____ to gonadal vessels
lateral
posterior
anterior
anterior
anterior
uterine arteries are branches of the _____ and joins the ovarian artery at the level of the ______
internal iliac artery
fallopian tubes
broad ligament (what, function)
not true ligaments
double fold of peritoneum
supports uterus, encloses oviducts, divided pelvis into ant/post, prevents side to side movement
round ligament (extends, function)
extends from lateral uterus to anterior pelvic wall
responsible for anterior tilt of uterus
ovarian ligament between
the ovary and lateral uterus
cervical (cardinal) ligament (extends, function)
from lateral cervix to pelvic floor
stabilizes cervix and prevents downward displacement of uterus
anterior cul-de-sac (female pelvis) (AKA, location)
vesicouterine pouch
peritoneum draped between the post bladder wall and ant to surface of uterus
posterior cul-de-sac (female pelvis) (AKA, location)
rectouterine pouch/Pouch of Douglas
peritoneum drapes between the ant rectum and post uterus
most dependent portion of the pelvis
space of Retzius female pelvis (AKA, location, filled with)
retropubic/prevesicular space
between symphysis pubis and ant bladder
filled with extraperitoneal fat
