28 A (Female Reproductive System) Flashcards
both female & males have primary sex organs called
gonads
how are the gonads differed by sex?
females have ovaries, males have testes
gonads produce sex cells called
gametes
what is different about the gametes produced by sex?
females produce oocytes, males produce sperm
what sex hormones do females product?
estrogen & progesterone
what sex hormones do males produce?
testosterone
this transports gametes from gonads to sites of ferritization
ducts
describe the structure of the ovaries
paired, oval organs, slightly larger than an almond
what are the functions of ovaries?
(1) oocyte (gamete) maturation & release
(2) sex hormone secretion (estrogen & progesterone)
this structure is anchored within the pelvic cavity by cords & sheets of CT
supporting tissues
list the types of supporting tissues
(1) broad ligament
(2) ovarian ligament
(3) suspensory ligament
peritoneum draping uterus
broad ligament
anchors ovary to lateral uterus
ovarian ligament
attaches lateral ovary to pelvic wall
suspensory ligament
within the ovary’s cortex (outer region), there are thousands of what?
ovarian follicles
what is an ovarian follicle?
a follicle consisting of an oocyte surrounded by follicle cells
this structure extends laterally from both sides of the uterus towards ovaries
uterine tubes
where are oocytes usually fertilized?
in the lateral part of the uterine tube
what are the regions of the uterine tube?
(1) infundibulum
(2) ampulla
(3) isthmus
funnel-shaped lateral margin of the uterine tube
infundibulum
what are the fingerlike projections of the infundibulum called?
fimbriae
expanded region medial to infundibulum
ampulla
what part of the uterine tube does fertilization typically occur?
ampulla
medial to the ampulla & represents ~ 1/3 of entire length of uterine tube
isthmus
pear-shaped, thick-walled muscular organ within the pelvic cavity
uterus
inner space/cavity of the uterus
lumen
lumen is continuous with the uterine tubes in what way?
superolaterally
lumen is continuous with the vagina in what way?
inferiorly
what are functions of the uterus?
(1) site of implantation
(2) supports/protects developing embryo/fetus
(3) ejects fetus during labor
