Female Reproduction Anatomy Flashcards
ligaments supporting the female stuff
median umbilical ligament round ligament of uterus round ligament of ovary uterosacral ligament board ligament of the uterus suspensory ligament of the ovary
female spaces/pouches
supravesicular fossa
retropubic space
vesicouterine pouch
rectouterine pouch
supravesicular fossa
peritoneal depression anterior to the bladder, above the pubic symphysis
used for suprapubic approach to pelvic cavity
retropubic space
between bladder and pubic symphysis low, used for suprapubic approach
vesicouterine pouch
space between uterus and bladder when uterus is ante flexed (normal)
rectouterine pouch
between the uterus and rectum, defined by uterosacral ligament
how is the rectouterine pouch accessed
posterior fornix of the vagina
uterine prolapse
uterus protrudes into vagina
rectocele prolapse
rectum protrudes into vagina
cytocele prolapse
bladder protrudes into vagina
enterocele prolapse
intestine protrudes into vagina
what causes a prolapse
relaxed pelvic floor ligaments
damaged perineal body
excessive retroversion
parts of the uterine tube
fimbria infundibulum- first part of tube osteium- opening into peritoneal cavity isthmus- narrow area intramural- in uterine wall
salpingitis
uterine tube infection
what is the blood supply of the uterine tuve
ovarian artery
peritinitis
infection in the peritoneal cavity
blood supply to uterus
ovarian and uterine
ligments on the ovary
suspensory ligament- holds ovarian vessels
ligament of ovary- ovary to uterus
mesosalpix- part of broad ligament
bloods supply of ovary
ovarian vessels
which vaginal wall is longer
posterior
palpable structures on pelvic exam
posterior- rectum, rectouterine pouch
anterior- bladder, urethra
lateral- ureters, uterine vessels, ovaries if enlarged
vaginal blood supply
upper 1/3- uterine artery
middle- vaginal artery
lower- pudenal
mesovarium
ovary to mesometrium
mesosalpnix
surrounds uterine tuves
mesometrium
connects uterus to lateral wall
ovarian arteris
branch off aorta at T12
travel in suspensory ligament of the ovary
supply ovary and uterine tubes
uterine artery
branch off internal iliac
uterus, upper 1/3 of vagina
in transverse cervical ligament (cardinal)
vaginal artery
branch off internal iliac
lower vagina
internal pudendal artery
branch of internal iliac
supplies perineum, posterior labia, vestibule of vagina
lymph of ovary and uterine tubes
lumbar nodes
lymph of uterus and vagina
internal iliac nodes
lymph of round ligament of uterus
inguinal nodes
what forms the frenulum and prepuce
the labia minora
what is in the vestibule of vagina
vaginal orifice
urethral orifice
opening of paraurethral glands
opening of greater vestibular glands
homolog of the greater vestibular glands
seminal vesicle
homolog of the lesser vestibular glands
prostate
homolog of the bulb of the vestibule
bulb of the penis and accompanying corpus spongiosum
contents of the superficial perineal space
ishiocavernosus muscle clitoris glans and crura bulbospongiosus muscle bulbs of vestibule greater vestibular glands superficial perineus muscle
female erectile tissues
clitoris and bulb of vestibule
ishiocavernosus muscle covers the
crura of the clitoris
bulbospongiosus muscle covers the
bulb of the vestibule
contents of deep perineal space
external urethral sphincter compressor urethrae urovaginal sphincter deep transverse perineus dorsal verve of the clitoris dorsal artery of the clitoris
location of external urethral sphincter
circular muscle around the urethra at the neck of the bladder and then spreads out
location of compressor urethrae
formed by spreading out of the external urethral sphincter around the vagina
location of urovaginal sphincter
formed by external urethral sphincter around the hiatus
lymphatic drainage fot he perineum
goes to the same sine + 1 cm across midline (midline overlaps)
follows inguinal nodes or iliac nodes if along internal pudendal artery
perineum innervation
posterior labial nerve- cutaneous to labia
anterior labial- fron ilioinguinal
perineal branch of posterior cutaneous of thigh- outside labia majora
pudendal nerve block
needle through vaginal wall aimed at the sacrospinous ligament
gets posterior labial nerve only
full anesthesia of perineal area
posterior labial (pudendal) anterior labial (ilioinguinal) perineal (cutaneous nerve of thigh)
episiotomy
surgical cutting of the perineal body for more room for child birth
suboccipitolbregmatic measurement
baby head size
transverse diameter of pelvic inlet
widest part of pelvis, between the top of the ischial spines
obstetric conjugate distance
distance from sacral promontory to the middle of the pubic symphysis, indirectly measured by the diagonal conjugate
diagonal conjugate distance
distance from sacral promontory to the inferior pubic symphysis
measured by inserting fingers into vagina and palpating the sacrum and measuring to the pubic symphysis
interspinous distance
distance between ischial spine and location of baby head
ischial spine to tuberosity is 5cm
structures above the pelvic pain line
ovary, uterine tubes, upper uterus
visceral pain path above pelvic pain line
sympathetic T12-L2 segments, hypogastric plexus and lumbar splanchnic nerves
structures below the pelvic pain line
cervix, vagina, perineum
visceral pain path below the pelvic pain line
parasympathetic S2-4 via pelvic splanchnic nerves
somatic pain below the pelvic pain line
pudendal and posterior labial nerves
