(1) hairy
(2) smooth.
labia minora
thin folds of skin
devoid of fat
b/w 2 labia majora
anterior pair of labia minora joins to form
prepuce of clitoris
posterior pair of labia minora joins to form
frenulum of clitoris
2 labia minora unite posteriorly to form
fourchette
clitoris is formed of
2 corpora cavernosa ONLY
clitoris crura are covered by
ischiocavernous muscle
clitoris ends in
glans clitoridis
vestibule orifices (3)
1-urethral
2-vaginal
3-orifices of Bartholin’s glands
bulbs of vestibule are covered by
bulbospongiosus muscle
arterial supply of vulva
1-superficial & external pudendal branches of femoral artery
2-posterior labial br of internal pudendal artery
veinous drainage of vulva
same as arteries

lymphatic drainage of vulva
superficial inguinal LNs
female 1ry sex organ
ovary
ovary site
ovarian fossa of lateral pelvic wall
ovary is bounded anteriorly by
obliterated umbilical artery
ovary is bounded posteriorly by
ureter
internal iliac artery
ovary is attached to upper end of broad ligament by
mesovarium
size of ovary
3m long
1.5 cm wide
1cm thick
shape of ovary
almond shaped
before puberty ovary is
smooth & greyish-pink
after puberty ovary is
puckered & irregular + greyish
in old women ovary is
atrophic
long axis of ovary is nullipara women is
vertical
long axis of ovary in multipara women is
horizontal
tubal end of ovary is related to
uterine tube
tubal end of ovary is attached to ____&_____by______
ovarian fimbria & side wall of pelvis by suspensory ligament of the ovary
uterine end of ovary is connected to superolateral aspect of uterus by
ligament of ovary
anterior attached border of ovary forms
hilum of ovary
anterior attached border of ovary is attached to____by____
broad ligament by mesovarium
posterior border of ovary is related to
uterine tube & ureter
lateral surface of ovary is related to
parietal peritoneum
parietal peritoneum separates ovary from
obturator nerve & vessels
medial surface of ovary is related to
fimbriated end of fallopian tube
uterine tube triple relations w/ ovary
tubal end
posterior border
medial surface

mesosalpinx
pt of broad ligament b/w mesovarium, ligament of ovary & tube
MC pathway for ascending infections to the peritoneum
abdominal ostium
salpingitis
inflammation of tubes
pyosalpinx
accumulation of pus in tubes
MC site of ectopic pregnancy
fallopian tubes
ligation of fallopian tube used for
birth control
blood supply of medial 2/3 of fallopian tube
uterine vessels
blood supply of lateral 1/3 of fallopian tube
ovarian vessels
nerve supply of lateral 1/3 of fallopian tube
ovarian plexus
blood supply of medial 2/3 of fallopian tube
uterine plexus
most of fallopian tube sends lymphatics along
with fundus & ovary—> lateral aortic & pre-aortic LNs
isthmus & utero-tubal junction send lymphatics along
round ligament—> superficial inguinal LNs
