Lecture 30: Female Reproductive System Flashcards
1.vagina
2.rectouterine pouch
3.ovary
4.uterine tube
5.uterovesical pouch
6.urinary badder
7.urethra
is uterus intra or retroperitoneal
intra
what pouches are formed by peritoneum in F pelvic cavity
uterovesical pouch and rectouterine
lowest point in peritoneal cavity in F
rectouterine pouch
1.ovarian ligament
2.fimbriae
3.infundibulum
4.ampulla
5.isthmus
ovaries
produce ovum and E and P
which ligament holds ovaries in place
1.ligament of the ovary
2.suspensory ligament
3.mesovarium
ligament of the ovary
attaches inferior pole of ovary to lateral wall of uterus
suspensory ligament
double layer fold of peritoneum that attaches superior pole of ovary to posterior abdo wall. carries oarian vessels/nerves
mesovarium
double layer fold of peritoneum btw anterior border ovary and posterior layer broad ligament. carries vessels/nerves from broad ligament into ovary via hilum
uterine tubes
connect uterine cavity to peritoneal cavity. carries sperm toward ovaries, or fertilized egg toward uterine cavity.
=infundibulum, ampulla, isthmus, uterine part
infunidbulum
lateral end of tube, hangs over ovary. has finbriae which attach to ovary
collects released ovum
ampulla
most dilated part of uterine tube. forms lateral 2/3
isthmus
narrowest part of uterine tube. forms the medial 1/3
uterine part (intramural) uterine tube
passes thru thickness of uterine wall, opens into cavity
uterus parts
fundus: superior to entrance of uterine tubes
body: middle part. distal third of it is the isthmus
3.cervix: btw isthmus and vagina
internal os
opening from uterine cavity to cervical canal
external ox
cervical canal opens to vagina thru this
anteversion angle
angle btw axis of cervix and axis of vagina
anteflexion angle
angle btw axis of uterine body and axis of cervix
ligaments of uterus
- broad
- round
- transverse (cervical)
4.pubocervical
5.uterosacral
1.fornix
2.lumen of uterus
3.internal os
4.cervical canal
5.external os
6.vagina
fornix
circular space around cervix where it enters vaginal canal
high risk area for cervical cancer
external os. transition point of tissue type
broad ligament
doible layer peritoneum. in btw are uterine tubes, uterus, ovaries, ligaments
divided into:
1.Mesosalpinx: close to uterine tube
2.Mesovarium: close to ovaries
3.Mesometrium: attached to site uterus
round ligament oterus
invested in btw two layers broad ligament. cross section is circular. produces ridge as it travels btw two layers
starts from uterus, passes thru inguinal canal, blends with labium major
stabilizes uterus in specific position
uterosacral ligament
btw uterus and upper part of vagina anteriorly, sacrum posteriorly
1.broad ligament
a.mesoalpinx
b.mesovarium
c.mesometrium
2.round lig of uterus
3.uterosacral lig
transverse cervical ligament
connects uterine cervixx and superior part of vagina to lateral pelvic wall
what maintains angle of anteversion and anteflexion
uterine ligaments
where is semen deposited
fornix. stays for 20-30 min. enzymes denature protein
vagina
fibromuscular tube starts at vestibule, ends at ervix
1.vestibule
2.urethral orifice
3. clit
4.labia majora
5.labia minora
6.vaginal orifice
vestibule
space btw two labia minoras
receives opening of urethra anteriorly and vagina posterioy
what is clit made of
3 columnar erectile tissue
root is made by two crura of clitoris (covered by muscle)
and bulb of clitoris
major vestibular gland sits close to vestibule. equivalane to bulbourethral in M. produce lubrication
1,2=crura
3. bulb of clitoris
4.major vestibular gland
5.vestibule
1.suspensory ligament
2.pec major
3.adipose tissue
4. lobe
5. lactiferous duct
suspensory ligaments
extension of fascia of pec major. divides breast into lobes and attaches tissue of gland to chest wall.
length of lig will determine shape of breast
lactiferous duct
each lobe has its own, opens to nipple
there are 7-15 lobes, so 7-15 ducts
what sensitizes skin of breast
intercostal nerve
lymphatic drainage breast
lateral half drains in axillary LN
medial half drains innto parasternal LN
vulva/pudendum
=external genitalia
=mons pubis, labia majora/minora, vestibule, clit, greater vestibular glands
mons pubis
skin prominence in from of symphysis pubis, contains fat
labia majora
two skin folds that contain fat. eq.. to scrotum. has hair after puberty
labia minora
two hairless skin folds
root of clit
formed by L and R curra and the R and L bulbs of vesituble.
mammary glands
modified sweat glands within superficial fascia of pectoral region. rib II to VI
blood supply breast
internal thoracic artery, anterior/osterior intercostal arteries, and axillary artery
what controls secretion milk
prolactin and oxytocin secreted by anterior pituitary and HTh
blood supply to ovaties/testes
gonadal branches of abdo aorta.
visceral branches of internal iliac arteries supply remianing repro organs
symphathetic innervation to ovaries/testes
lumbar splachnic nerves
PSN innervation to gonads
pelvic splachnic
innervation of internall and external repro organs
sympathetic= lumbar and sacral splachnic
parasumpathetic= pelvic splachnic
