Female reproductive system Flashcards
What is the main function of ovaries?
create and secrete eggs
What are the structures of the Ovaries?
Medulla, Cortex, Tunica Albuginea, Germinal epithelium, blood vessels
Journey of the the Follicle
Primordial follicle–>Primary follicle–>secondary follicles—>Vesicular follicle—->ovulation—-> Developing corpus luteum—> Corpus Luteum—-> dying corpus lutuem
low estrogen triggers what release?
FSH release
what does FSH releas do?
promotes development of the primary and secondary follicles
What causes Estrogen levels to rise, triggering a surge in what hormone? an what does it do.?
secondary follicles, LH hormones which triggers ovulation
Corpus luteum produces what hormone? what is it s purpose?
progestrone; hormone needed for pregnancy
Ovarian cyst
cyst developed by a continued growth of follicle, ovulation never happens, when ruptured can be extremely painful
Fimbriae
finger like structure at the end of fallopian tube; responds to hormones released by the follicle so that is catches the released ovulated egg
Infundibulum
funnel shaped cavity in the fallopian tube
Ampulla
longest part of the fallopian tube
Isthmus
the narrowest part of the fallopian tube
Intramural
passes through the walls of the uterus
How does the ovulated egg move through fallopian tube to the uterus?
ciliated epithelium that contains mucosa
Uterus structure
fundus, body, cervix
describe two tissues in the uterus.
Endometrium- deep, contains epithelium cells
Myometrium- fibromuscularis layer, smooth muscle
what happens when oxytocin levels are high?
contraction of the uterus will be more frequent, common in birth
describe cervix
lowest part of uterus, thick wall due to more muscle
what happens at the secretory phase of the menstrual phase?
uterine line at maximum, hormone maintain the wall my secreting progesterone
What happens during fertilization?
increase in progesteron increase endometrium
What happen when fertilization does not occur?
decrease in progesteron decrese endometrium= period
What two hormones does birth control maintain and why?
progesterone and estrogen so that ovulation never occurs
what is the prepuce?
flap of skin that covers/protects clitoris
what is the clitoris?
a bundle of nerves
Glans of clitoris?
similar to male reproductive system
