female pelvis Flashcards
ureter (pelvic part)
crosses the bifurcation of common illiac artery
infront of sacroilliac joint and internal illiac artery
behind ovary and fallopian tube.
crosses forward and medially under the base of the broad ligament of uterus where it crosses the uterine artery
enters the urinary bladder lateral to the lateral fornix of vagina
where is the urinary bladder located
in lower pelvis when empty, but extends to abdominal area when its full
in children its in the abdomen either way
nerve supply of the bladder
inferior epigastric plexus
symp: L1 & L2 inhibit contraction of detrusor muscle and stimulate closure of sphincters
parasymp: S2-S4 cause contraction of detrusor muscle and stimulate opening of sphincter
whats a detrusor muscle
the muscle that causes contraction to push urine through the urethra
neck of bladder rests on?
urogenital diaphragm
apex of the bladder
faces towards the upper part of pubic symphysis and forms medial umbilical ligament
inferolateral surfaces of bladder
faces the pubic symphysis and isn’t covered by peritoneum
superior surface of the bladder
covered by peritoneum
base of infero posterior surface of bladder
triangular
vagina sperates it from rectum
suprolaterally -> ureter
inferior angle -> urethra
vesicouterine pouch
between bladder and uterus
rectouterine pouch
douglas pouch
between rectum and uterus
extension of the peritoneum
ligaments of bladder
pubovesical ligament (pubic bone to bladder)
pubovaginal ligament (pubic bone to vagina)
vesicouterine ligament
urachus (connects apex to umbilicus to form median umbilical ligament)
interior of the bladder
the mucosa of bladder is thrown into folds except at trigone (smooth)
openings of ureters and urethra form a
trigone
slight elevation may be seen in posterior portion of internal urethral orifice in male subjects called
uvula
uterus divided into
fundus, body, and cervix
where is the fundus of the uterus
above the enterance of the uterine tubes
body of the uterus
below entrance of uterine tubes
cervix
continued narrowed part of the body and pierces the anterior wall of the vagina
anteversion
uterus bent forward on long axis of vagina
anteflexsion
long axis of the uterus is bent forward at level of internal os with the long axis of the cervix
retroverted
not good for pregnancy because it blocks the rectum and causes difficulty for defecation
retrocession
cervix projected backwards
where do we drain fluid in douglass pouch
vagina
ligaments supporting the uterus
transverse cervical
pubocervical ligaments
sacrocervical ligaments
round ligament of the uterus
muscles and tendinous bodies supporting the uterus
levator ani and perineal body
broad ligament
two layer folds of peritoneum
Suspensory Ligament of ovary (contains arteries, veins, and nerves)
mesoalpnix
mesoovarium
Uretrosacral ligaments
what causes mensuration
endomatrium
blood supply of uterus: branching of abdominal aorta:
ovarian artery
blood supply of uterus: branching of internal illiac artery:
uterine artery
vaginal artery
lymphatic supply of uterus
fundus: para aortic
body and cervix: internal and external
few into superficial inguinal LN
fallopian tubes
consists of isthus, ampulla infundibullum and fimbriae
site for fetrilization is
ampulla
vaginal lumen
two lateral, posterior and anterior fornix
blood supply of vagina
vaginal branch from internal illiac artery and vaginal branch of uterine artery
lymphatic supply of vagina
upper third drain into external and internal iliac lymph node, middle third to internal iliac and lower third to superficial inguinal lymph node
where do ovaries lie
ovarian fossa
ovaries are surrounded by fibrous capsule called
tunica albuguinea
ovaries are bound by which vessels
internal and external iliac vessels
Ovaries attached to the posterior part of the broad ligament by
mesovarium
function of the ovary
production of ova, estrogen and progestrone
blood supply of ovary
ovarian artery
veins: ovary
IVC on right and left renal on left side
lymphatics: ovary
para aortic lymph nodes
ovary nerve?
aortic plexus
what anastomoses with uterine artery
vaginal artery
cyctocele
bladder prolapse
