female pelvis Flashcards
name the bones that make the female pelvis
ilium, ischium, pubis, sacrum, coccyx
bones that form the lateral &anterior wall of pelvis
innominate:
- ilium
- ischium
- pubis
bones that form the posterior wall of pelvis
sacrum & coccyx
the socket for the femoral head (outer surface of each of the innominate bones)`
acetabulum
what structure separated the True & False pelvis
linea terminalis
“pelvic brim”
linea terminalis
3 functions of female pelvis
- weigh bearing bridge
- directs pathway of femoral head
- protects reproductive organs
true pelvis organs
pelvic colon rectum bladder uterus ovaries FT vagina suspensory ligaments
false pelvis organs
ileum & sigmoid colon
__ pelvis is inferior portion of each ileum, ischium, both pubic bones, sacrum & coccyx
true
what pelvis is superior to the linea terminalis
false
muscles that make up the pelvic floor
- Coccygeus
2. Levator ani
muscles responsible for controlling deification
levator ani
muscles of levator ani
- puborectalis
- pubococygeus
- illiococcygeus
muscle that provides sacral support
coccygeus
muscle responsible for midline anterolateral suppirt that tenses floor of pelvis, elevates and retracts anus
pubococcygeus
posterolateral support, restricts anus
illiococcygeus
anterior support
puborectalis
Two Muscles fill in the space of the True Pelvis and are functionally related to hip movement.
- Piriformis muscle
2. obturator internus
fill in the greater sciatic notches and arise from the sacrum.
piriformis
extend posteriorly and insert into greater trochanter
piriformis
easily mistaken for ovaries on US
piriformis
exit the pelvis thorough the lesser sciatic notch to the greater trochanter
obturator internus
anterior pelvic muscle
rectus abdominis
fusion of L and R rectus abdominis forms ___ (echogenic line)
linea alba
muscles of pelvis: Posterior wall
psoas major & piriformis
muscles of pelvis: posterior floor
coccygeus
muscles of pelvis: middle and anterior floor
levator ani
muscles of pelvis: lateral wall
obturator internus
false pelvis muscle
illiacus
Name the main arteries in the pelvis
- common iliac arteries
a) internal (pelvis)
- - rectal & pudendal (inf.)
- -gluteal (superior)
b) external (legs)
- -femoral
Name organs of female pelvis
- Ovaries
- Uterus
- urethra
- Vagina
- Fallopian tubes
- bladder
- colon and rectum
Name the ligaments of the uterus.
- cardinal (lateral cervical)
- uterosacral (cervix to sacrum)
- broad ligament
- round ligament
ligaments that anchor the cervix
- cardinal
- uterosacral
ligament that tether around the uterine fundus and tilt it forward in pelvis
round ligament
double fold of peritoneum ligament
broad
divides the tru pelvis into anterior and posterior
broad ligament
suspends the uterus
broad ligament
ovaries attach to the posterior surface of the __
broad ligament
ligaments of the ovaries
a. Suspensory
b. Ovarian
c. Mesovarium
what lies between the anterior wall of uterus and the UB
anterior cul de sac (vesicouterine pouch)
peritoneum between the rectum and posterior wall of the uterus
posterior cul de sac/ puch of douglas/ rectouterine pouch
Lies along the free edge of the broad ligament
FT
length of FT
7-12 cm
FT divide into 4 parts:
- infundibulum
- ampulla
- isthmus
- intersitital/ intramural
ligament extends from the uterine to the ovary
ovarian
ligament passes from pelvic brim to lateral pole of ovary
suspensory (infundibulopelvic)
from posterior surface of broad ligament, provide primary route for vessels entering ovarian hilum
mesovarium
