What supports the fallopian tube
mesosalpinx of the broad ligament
26
What structure supports the ovary
mesovarium
27
What part of the broad ligament supports the uterus
mesometrium
28
What do the fimbrae do
They pull in oocytes from the ovary into the fallopian tube
29
What is the largest aspect of the fallopian tube
Ampulla Where fertilization occurs
30
How big are the ovaries
roughly the size of an almond
31
What do the ovaries produce
sex hormones also contains the oocytes
32
What is the most important hormone for egg development
estrogen
33
What is the difference between the oocyte and an ovum
oocyte is developing ovum is a mature egg
34
What structure contains an unfertilized oocyte
follicle
35
How many eggs are women born with
3 million
36
How many oocytes do women have at puberty
300,000
37
what is a primordial follicle
primary oocyte with one layer of granulosa cells *stuck in prophase 1
38
What is a primary follicle
advancing primordial stimulated by FSH with beefier granulosa cells
39
What is a secondary follicle
more granulosa cells that secrete follicular fluid
40
What are the phases of the ovarian cycle
follicular luteal
41
What is responsible for giving nutrients to the ovum for development
granulosa
42
What hormone will increase follicular growth
FSH** LH
43
How many follicles will reach the primary follicular phase each month
6-12
44
What occurs when granulosa cells start to proliferate
secondary follicle
45
What layer around the proliferating cells will produce estrogen
Theca layer
46
What is the purpose of estrogen acting on the follicle
increase FSH receptors
47
What will estrogen and FSH do to the follicle they're acting on
increase LH
48
When does ovulation occur in the cycle
day 14
49
What encases the expressed. ovum
corona radiata
50
What is the corona radiata
Mass of granulosa cells
51
When does LH secretion increase dramatically
2 days before ovulation
52
What is the corpus luteum
The cells that remain after expulsion of the ovum
53
What does the corpus luteum produce
progesterone
54
Which layer is the functional layer of the endometrium
stratum functionalis
55
What makes the stratum functionalis grow
estrogen
56
What activates the stratum functionalis
progesterone
57
What phase marks the completion of menstruation
Proliferative
58
What hormones causes proliferation of the stroll cells and epithelial cells
Estrogen
59
What hormone is the primary driver of the secretory phase
Progesterone
60
how long once an egg is released does someone have to fertilize it
12-24 hours
61
What causes menstruation to occur
a decrease in progesterone which will call the vessels to become vasospastic
62
What causes the uterus to contract to excrete menstrual flow
Prostaglandins
63
What fluid is contained within menstrual fluid
40mL blood 35mL serous fluid
64
Why are there typically no clots with menstruation
fibrinolysin
65
how frequently is GnRH released
every 1-2 hours for 5-25 minutes
66
What is the main job of progesterone
prep the uterus for housing the fetus lactation
67
Where is estrogen made
primarily made in the ovaries also the zona reticularis
68
How does estrogen effect osteoclasts
prevents them
69
How does estrogen effect the kidneys
retain Na+ and H2O
70
How does estrogen effect the vaginal cells
changes them from cuboidal to stratified
71
How much do gonadotropins increase in puberty
20x increase
72
Where is progesterone broken down
in the liver and released in bile or urine
73
What role in breast development does progesterone have
helps develop the lobules and alveoli
74
When in their cycle are women more sexually aroused
around day 14
75
What do female orgasms help with
fertilization
76
How long will the cervix dilate after orgasm
Around 30 minutes post orgasm
77
What may cause the uterine contractions s/p orgasm
thought to promote oxytocin release
78
What causes sexual arousal
parasympathetic control from the sacral plexus, causing the dilation of the erectile tissue acetylcholine is released
