Q

primary follicles

A 
20-50/month respond to FSH
 - still in prophase 1

Q

What causes ovulation

what cells are receptive

A

surge of LH
granulosa and theca cells
- usually one 1 follicle responds

25
stigma formation? | spot where graafian follicle breaks out of ovary
follicular near albuginea thins out. decreased blood flow. rupture --> cumulus mass and follicular fluid go out and captured by fibria
26
Role of FSH
stimulates granulosa cells and estrogen synthesis later -> formation of LH receptors
27
Role of LH
simulates thecal cell growth and androgen production - granular cells convert the androgens to estrogen stimulates progesterone production by granular cells
28
temporary glandular structure from ruptured follicle
corpus leuteum | - its granular cells and thecal cells left over
29
granular cell becomes this after LH surge
granulosa lutein cells - steroid secreting - make estrogen and progesterone
30
theca cell becomes this after LH surge
theca lutein cells - steroid secreting - make estrogen and
31
name of scar formed from corpus luteum
corpus albicans
32
after ovum is dischared, what is the remaider in the ovary called?
corpus luteum
33
2 types of corpus luteum
``` corpus luteum of menstration - always forms. turns into scar if pregnancy doesnt happen corpus luteum of pregnancy - after implantation - maintainted by HCG from trophoblasts - persists for 1st trimester ```
34
estrogen made by what functions?
made from growing follicle and granulosa cells maturation of reproductive tract repairs uterus after menstruation grows yer boobies
35
progesterone made by what functions?
corpus lutem uterine gland secretion prepares uterus for implantation growth of mammary glands inhibits uterine contractions
36
relaxin made by what function
corpus lutem and decidual cells of placenta inhibits contractions promotes dilation of cervix
37
inhibin role
negative feedback of FSH
38
What's the oviduct? | what are the parts of it called?
it's the fallopian tube ampulla - open end with fimbria isthmus intramural portion
39
Ampula mucosa epithelium type 2 cell types
lots of branching folds simple columnar peg cells - secretes tubal fluid ciliated cells - transport egg
40
isthmus cilia? folds?
fewer folds, some ciliated cells | still active secretory cells
41
intramural segment cilia? folds?
no folds | no cilia
42
non-epithilial layers of the oviduct
lamina propria muscularis - inner layer of circular muscle - outer, longitudinal layer
43
3 layers to uterus
endometrium myometrium perimetrium
44
endometrial layer of uterus | epithelium type
simple columnar there are tubular glands lamina propria has mesenchymal cells and CT
45
layer of endometrium that doesn't get shed
basal layer | - it' deep and narrow
46
2 layers of superficial layer of endometrium characteristics of the glands in each layer
``` superficial - narrow - strait glands deep spongy - most of endometrium - edema - glands have large lumens ```
47
how many layers in myometrium
3, they're intertwined though
48
perimetruim
loose conective tissue (serosa)
49
blood supply of uterus
uterine artery --> arcuate arteries --> branch to strait and spiral arteries strait (basal) spiral (functional layer)
50
Phases of menstrual cycle
``` proliferative (estrogen) secretory (progesterone) premenstrual (ischemic) menstrual repair ```
51
proliferative phase length starts when?
1-2 weeks | starts @ end of menstrual flow, induced by estrogen
52
secretory phase length starts when?
2-3 weeks starts at ovulation - lots more progesterone, also most estrogen glands begin to secrete glycogen and look wavy coiled arteries enlongate
53
premenstrual stage happens when?
``` days 27-28 - corpus leutum regresses decline in progesterone less edema anoxia --> necrosis ```
54
menstrual phase how long what happens
few days functional layer --> necrosis blood doesn't clot
55
repair phase | what happens
re-epithelization | coiled arteries regrow
56
cervix. 2 layers and what they're made of
``` lamina propria - dense CT Myometrium - dense CT - smooth muscle ```
57
What is cervical mucous made of | 2 things that change the viscosity
glycoprotein estrogenic mucus - low viscosity (helps sperm migration) gestrogenic mucous - high viscosity
58
where does most cervical cancer present
the squamoucolumnar junction
59
vagina epithelium
stratified squamous, non-keritinizing
60
vaginal mucosal changes during various stages of menstration
``` follicular phase - proliferation - glycogen storage - eosinophilic luteal phase - less height - exfoliated cells are basophilic ```
61
vaginal lamina propria features
dense CT leukocytes elastic fibers rugae
62
muscularis of vagina features
interlaced smooth muscle | bulbocaernousum is skeletal muscle that makes a sphicter around osteum of vagian
63
adventitia of vagina
thin layer of loose CT | venous plaxuses
64
what causes the vagina to store glycogen | what actually makes it
estrogen | made from lactobacilli --> makes environment acidic to stpo infections
