opening
FALLOPIAN TUBE what does infundibulum contain
fimbriae
FALLOPIAN TUBE what is the function of fimbriae
sweep secondary oocyte into fallopian tube

fertilization
what is mespsalphix
broad ligament surrounding fallopian tubes
what is mesovarium
broad ligament surrounding ovaries
what is mesometrium
broad ligament surrounding uterus
what is broad ligament
2 layers of parietal p draping over entire female repro system
SUPPORTING LIGAMENTS what are ligaments
- thickening of parietal p
2. thickening of tissue in pelvis
SUPPORTING LIGAMENTS where do ovaries receive vasculature
abdominal aorta
SUPPORTING LIGAMENTS what do ovarian arteries and veins do
go through parietal p
SUPPORTING LIGAMENTS what is suspensory ligament
ovarian arteries and veins enveloped by parietal p
SUPPORTING LIGAMENTS what is the function of suspensory ligaments
anchor ovaries to posterior abdominal wall
SUPPORTING LIGAMENTS what is the function of ovarian ligament
anchor ovaries to uterus
SUPPORTING LIGAMENTS what is the function of round ligament
anchor ovaries to anterior abdominal wall
SUPPORTING LIGAMENTS what is the function of transverse ligaments
anchor uterus to lateral wall
SUPPORTING LIGAMENTS what is the function of uterosacral ligament
posterior anchoring of uterus
what kind of glands are ovaries
endocrine
what do ovaries contain since they are endocrine glands
- medulla
2. cortex
what is vasectomy
- remove vas deferns
2. retain testes
what is result of retaining testes
continue producing testosterone
what is uterectomy
- remove uterus
2. retain ovaries
what is the result of retaining ovaries
continue producing estrogen + progesterone
OOGENESIS what is oogenesis
production of gamete (ovum)
OOGENESIS what happens before birth
- mitosis ==> primary oocyte + oogonia
2. DNA replication ==> primary oocyte
OOGENESIS what happens at birth
suspended in meiosis 1 ==> primary oocyte
OOGENESIS what is required for completion of meiosis 1
FSH
OOGENESIS what is produced in meiosis 1
- first polar body
2. secondary oocyte
OOGENESIS what stimulates ovulation
LH
OOGENESIS what happens during ovulation
secondary oocyte starts meiosis 2
OOGENESIS what is produced in meiosis 2
- second polar body
2. ovum
OVARIES what occurs in cortex
- oogenesis
2. ovarian cycle
OVARIES what does cortex contain
- capillaries
2. follicle cells the surround oocyte
OVARIES what is medulla closer to
parietal p
OVARIES what is cortex closer to
vasculature
OVARIES what is female born with
- primary oocyte
- follicle cells
=primordial follicle
what are the steps of follicular development
- primordial
- primary
- secondary
- mature
PRIMORDIAL what is primordial follicle
- primary oocyte
2. follicle cells
PRIMORDIAL what are follicle cells
simple squamous
PRIMARY what is the function of FSH
stimulate follicles surrounding primary oocyte
PRIMARY what happens to stimulated follicles
- become granulosa cells
- become theca cells
PRIMARY what do primary oocyte + granulosa cells form
basil mem / zona pellucida
PRIMARY what is primary follicle
- primary oocyte
- granulosa cells
- theca cells
SECONDARY what happens during secondary follicle development
few primary follicles develop into secondary follicles
SECONDARY what is antral fluid
fluid secreted by granulosa cells
SECONDARY what do granulosa cells + theca cells release
- estrogen
2. progesterone
SECONDARY what is the function of estrogen
- support re-growth of endometrium layer after menstruation
- feedback to pituitaty to decrease release of FSH
+ increase release of LH (when estrogen levels become too high)
MATURE what happens during mature follicle development
one secondary follicle develops into mature follicle
MATURE what happens to primary oocyte
- complete meiosis 1
- become secondary oocyte
MATURE what is the function of granulosa cells
lift secondary oocyte
MATURE what happens after granulosa cells lift secondary oocyte
- some degenerate
2. some survive
MATURE what happens when some of the granulosa cells degenerate
secondary oocyte becomes free floating
what happens to the follicles that started maturation but did not reach mature follicle development
continue to produce estrogen
what is required for the release of LH
estrogen
OVULATION what is required for ovulation
LH
OVULATION what is the function of theca cells
secrete enzymes that chew through cortex and parietal p
OVULATION what happens after ovulation
enter luteal phase
LUTEAL PHASE what is the function of granulosa cells + theca cells
develop into corpus lutetium
LUTEAL PHASE how is corpus lutetium maintain
presence of LH
presence of hCG
LUTEAL PHASE when is hCG produced
after implantation
LUTEAL PHASE what happens if there is no implantation
