pubococcygeus
What is the function of the levator ani?
form the pelvic foor, supports and positions pelvic organs
testicle
egg shaped organ within scrotum, produces sperm and male hormones
epididymis
duct posterior to testicle that transports sperm to vas deferens
EJ duct
formed where the vas deferens meets seminal vesicle, pass through prostate and open to urethra
seminal vesicles
paired glands at posterior to bladder and superior to prostate
prostate
gland surrounding neck of urinary bladder and male urethra
bulbourtheal gland
pea shaped glands inferior to prostate and just proximal to penile tissue
corpus cavernosum
two masses of erectile tissue (anterior) forming most of the penis
corpus spongiosum
single smaller mass of erectile tissue surrounding urethra (posterior)
In a transverse transabdominal bladder and prostate image, where are the organs located?
bladder: anterior
prostate: posterior
In a sagittal transabdominal bladder and prostate image, where are the organs located?
prostate is seen posterior and inferior to bladder
What is the broad ligament?
double fold of peritoneum covering the fallopian tubes, ovaries, uterus, & blood vessels
Where does the broad ligament attach?
extends from lateral walls of uterus to sidewalls of pelvis
What is the cardinal ligament?
thickening at base of the broad ligament
Where does the cardinal ligament attach?
lateral cervix and vagina to pelvic wall
Where does the ovarian ligament attach?
extends from cornua to medial aspect of ovary
Where does the round ligament attach?
arises from the cornua anterior to fallopian tubes and extends to pelvic sidewalls
Where does the suspensory/infundibulopelvic ligament attach?
extends from lateral ovary to pelvic sidewall
Internal iliac arteries
branch of the common iliac
posterior to uterus and ovaries
uterine arteries
branch of internal iliac arteries, supplies vagina, uterus, cervix, fallopian tubes, and ovaries
arcuate arteries
branch of uterine arteries
prominent vessels in outer 1/3 of myometriumi
ovarian arteries
branch off aorta just inferior to the renal arteries
supply ovaries
Where does the right ovarian vein empty into?
The IVC
Where does the left ovarian vein empty into?
left renal vein
What are the spaces in the female pelvis?
retrouterine
anterior cul de sac
