Q

stigma formation?

spot where graafian follicle breaks out of ovary

A

follicular near albuginea thins out. decreased blood flow. rupture –> cumulus mass and follicular fluid go out and captured by fibria

26
Q

Role of FSH

A

stimulates granulosa cells and estrogen synthesis

later -> formation of LH receptors

27
Q

Role of LH

A

simulates thecal cell growth and androgen production
- granular cells convert the androgens to estrogen

stimulates progesterone production by granular cells

28
Q

temporary glandular structure from ruptured follicle

A

corpus leuteum

- its granular cells and thecal cells left over

29
Q

granular cell becomes this after LH surge

A

granulosa lutein cells

  • steroid secreting
  • make estrogen and progesterone
30
Q

theca cell becomes this after LH surge

A

theca lutein cells

  • steroid secreting
  • make estrogen and
31
Q

name of scar formed from corpus luteum

A

corpus albicans

32
Q

after ovum is dischared, what is the remaider in the ovary called?

A

corpus luteum

33
Q

2 types of corpus luteum

A 
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
Q

estrogen made by what

functions?

A

made from growing follicle
and granulosa cells

maturation of reproductive tract
repairs uterus after menstruation
grows yer boobies

35
Q

progesterone made by what

functions?

A

corpus lutem

uterine gland secretion
prepares uterus for implantation
growth of mammary glands
inhibits uterine contractions

36
Q

relaxin made by what

function

A

corpus lutem and decidual cells of placenta

inhibits contractions
promotes dilation of cervix

37
Q

inhibin role

A

negative feedback of FSH

38
Q

What’s the oviduct?

what are the parts of it called?

A

it’s the fallopian tube

ampulla - open end with fimbria
isthmus
intramural portion

39
Q

Ampula mucosa
epithelium type
2 cell types

A

lots of branching folds
simple columnar
peg cells - secretes tubal fluid
ciliated cells - transport egg

40
Q

isthmus
cilia?
folds?

A

fewer folds, some ciliated cells

still active secretory cells

41
Q

intramural segment
cilia?
folds?

A

no folds

no cilia

42
Q

non-epithilial layers of the oviduct

A

lamina propria
muscularis
- inner layer of circular muscle
- outer, longitudinal layer

43
Q

3 layers to uterus

A

endometrium
myometrium
perimetrium

44
Q

endometrial layer of uterus

epithelium type

A

simple columnar
there are tubular glands
lamina propria has mesenchymal cells and CT

45
Q

layer of endometrium that doesn’t get shed

A

basal layer

- it’ deep and narrow

46
Q

2 layers of superficial layer of endometrium

characteristics of the glands in each layer

A 
superficial
 - narrow
 - strait glands
deep spongy
 - most of endometrium
 - edema
 - glands have large lumens
47
Q

how many layers in myometrium

A

3, they’re intertwined though

48
Q

perimetruim

A

loose conective tissue (serosa)

49
Q

blood supply of uterus

A

uterine artery –> arcuate arteries –> branch to strait and spiral arteries
strait (basal)
spiral (functional layer)

50
Q

Phases of menstrual cycle

A 
proliferative (estrogen)
secretory (progesterone)
premenstrual  (ischemic)
menstrual
repair
51
Q

proliferative phase
length
starts when?

A

1-2 weeks

starts @ end of menstrual flow, induced by estrogen

52
Q

secretory phase
length
starts when?

A

2-3 weeks
starts at ovulation - lots more progesterone, also most estrogen
glands begin to secrete glycogen and look wavy

coiled arteries enlongate

53
Q

premenstrual stage happens when?

A 
days 27-28
 - corpus leutum regresses
decline in progesterone
less edema
anoxia --> necrosis
54
Q

menstrual phase
how long
what happens

A

few days
functional layer –> necrosis
blood doesn’t clot

55
Q

repair phase

what happens

A

re-epithelization

coiled arteries regrow

56
Q

cervix. 2 layers and what they’re made of

A 
lamina propria
 - dense CT
Myometrium
 - dense CT
 - smooth muscle
57
Q

What is cervical mucous made of

2 things that change the viscosity

A

glycoprotein
estrogenic mucus - low viscosity (helps sperm migration)
gestrogenic mucous - high viscosity

58
Q

where does most cervical cancer present

A

the squamoucolumnar junction

59
Q

vagina epithelium

A

stratified squamous, non-keritinizing

60
Q

vaginal mucosal changes during various stages of menstration

A 
follicular phase
 - proliferation
 - glycogen storage
 - eosinophilic
luteal phase
 - less height
 - exfoliated cells are basophilic
61
Q

vaginal lamina propria features

A

dense CT
leukocytes
elastic fibers
rugae

62
Q

muscularis of vagina features

A

interlaced smooth muscle

bulbocaernousum is skeletal muscle that makes a sphicter around osteum of vagian

63
Q

adventitia of vagina

A

thin layer of loose CT

venous plaxuses

64
Q

what causes the vagina to store glycogen

what actually makes it

A

estrogen

made from lactobacilli –> makes environment acidic to stpo infections
