pelvic organs Flashcards
anterior border of perineum
pubic symphysis
posterior border of perineum
coccyx
lateral border of perineum
ischial tuberosities
anteriorlateral border of perineum
ischiopubic ramus
posterolateral border of perneum
sacrotuberous ligament
anterior triangle of perineum
urogenital and/or vaginal canal
posterior triangle of perineum
anal canal
what muscle fills the perineum space
levator ani
two openings on the urogenital triangle
- urethral opening
- vaginal opening
what lies superior to the levator ani
perineal membrane
perineal membrane
- start point for mm
- maintain integrity of mm
- found on UG triangle
trigone of bladder
-formed by two openings of ureter and one opening of urethra
what lies posterior to bladder (female)
vagina and uterus
pathway between uterus and vaginal canal
cervix
uterus is anchored to the lateral wall and pelvic floor by
broad ligament
uterus is suspended by
round ligament
what holds/covers the ovaries
mesovarium (portion of broad ligament)
ovaries lie on top of what
broad ligament
ovaries are connected to uterus by
ovarian ligament
ovaries are connected to pelvic wall by
suspensory ligament
function of suspensory ligament
brings blood vessels
what runs along the superior free edge of broad ligament
uterine (fallopian) tube
opening of uterine tube
infundibulum
ends of infundibulum
finger-like projections
fimbria
where does fertilization occur
ampulla of uterine tube
opening of uterine tube into uterus
isthmus
function of fimbria
wave egg into uterine tube
the round ligament passes through what (female)
inguinal canal
what connects the ovaries to the broad ligament
mesovarium
what sits below bladder (males)
prostatE
what passes around the seminal vesicles
vas deferens
3 cylinders of erectile tissue
- 2 corpora cavernosa
- 1 corpus spongiosum
corpus cavernosum comes from
crus from pubic rami
corpus spongiosum originates from
perineal membrane
what forms the bulb of penis
corpus spongiosum
tip of corpus spongiosum
glans of penis
where is the spongy urethra found
corpus spongiosum
where does the urethra pass through (male)
corpus spongiosum
what surrounds the urethra when leaving the bladder
prostate
how many times does the urethra bend in males
twice
surrounds the testes
epididymis
ureter passes under (males)
seminal vesibles
function of seminal vesicle
produce alkaline type substance that protects the sperm against acidic environment of urethra and female reproductive tract
function of prostate
produce secretion that helps mobility and viability of sperm
thickened part of vas deferens
amupulla of vas deferens
path of semen
seminiferous tubules => epididymis => vas deferens => seminal vesicles
what leaves the seminal vesicles
ejaculatory duct
here is sperm produced
seminiferous tubules
ejaculatory duct empties into
prostatic urethra
