This is apart of what phase ?

A

Follicular

26
Q

A

LH

27
Q

_____ arrests estrogen synthesis in granulosa cells (sudden concentration drop)

A

LH

28
Q

____ triggers vascular changes and swelling to promote follicle rupture and oocyte release (ovulation)

A

LH

29
Q

Ovulated secondary oocyte has complete MI arrested in MII
This is apart of what phase ?

A

Ovulation

30
Q

What day of cycle is the follicular phase ?

A

1-13

31
Q

What day of cycle is the Ovulation phase ?

A

14

32
Q

Oocyte is surrounded by ZP and a Halo of granulosa cells and oocyte is captured by fimbriae of the oviduct
What phase does this occur

A

Ovulation

33
Q

What day of cycle is Early literal phase ?

A

15-22

34
Q

Remaining granulosa cells luteinize and form the corpus luteum
What phase does this occur?

A

Early luteal

35
Q

Produces high levels of steroid hormones progesterone and estrogen. Prepares endometrial layer ready for an embryo to implant
What phase does this occur?

A

Early luteal

36
Q

In the early luteal phase remaining granulosa cells “luteinize” and form the _____

A

Corpus luteum

37
Q

The uterus consists of______ (outer smooth muscle) and_______ (inner lining of epithelial cells, blood vessels and glands)

A

Myometrium
Endometrium

38
Q

High ____ concentrations in the follicular have rimes the endometrium, (PR) to respond to progesterone in the secretory phase

A

Estrogen

39
Q

High estrogen concentrations in the follicular phase primes the _____ to respond to progesterone in the secretory phase

A

Endometrium

40
Q

In the ____ phase the endometrial layer becomes loose and water filled (edamatous). Highly vascularized and glycogen loaded, suitable for implant implantation

A

Secretory

41
Q

In the secretory phase the ________ becomes loose and water filled , highly vascularized and glycogen loaded; suitable for embryo implantation

A

Endometrial layer

42
Q

In the secretory phase the endometrial layer becomes loose and water filled , highly vascularized and glycogen loaded; suitable for _________

43
Q

What day of cycle does the late luteal phase occur ?

A

24-28

44
Q

In the absence of embryo implantation , corpus luteum has a finite period of hormone-producing activity ; degenerates to corpus alibi and and estrogen & progesterone levels fall
