18
Q

Spiral arteries…

A

regenerate and degenerate, they constrict causing menstruation

19
Q

Ph level of uterus

A

acidic because of bacteria that produces lactic acid to prevent infection (prior puberty is not acidic)

20
Q

Layers of vaginal wall

A

fibroelastic adventitia
smooth muscle (muscularis)
stratified squamous mucosae with rugae

21
Q

fibroelastic adventitia (vagina)

A

lots of movement, no glandular tissue, just cervical mucus

22
Q

muscularis (vagina)

A

smooth muscle, can contract

23
Q

stratified squamous mucosa with rugae

A

deep layer, non keratinized, multiple layers deal with friction. rugae in organs collapse and expand

24
Q

mammary glands function

A

milk production: vitamins, nourishment immunity

25
Q

How many lobes in sweat glands?

A

15-25 lobes

26
Q

Suspensory ligaments in mammary glands

A

overlying skin with overlying muscle to hold breast

27
Q

the lobe in mammary gland

A

alveoli sac in lactiferous duct

28
Q

lactiferous sinus in mammary gland

A

collecting area when nursing

29
Q

flow of liquid in mammary gland

A

alveoli (lobules) —> lactiferous ducts —-> lactiferous sinus—->opening of lactiferous duct

30
Q

Ovulation occurs

A

midcycle between phases, monthly every 28 days

31
Q

ovulation is

A

the maturation of an egg

32
Q

Follicular phase

A

period of vesticular follicle phase (days 1-14)

33
Q

luteal phase

A

period of corpus luteum activity (days 14 -28)

34
Q

The luteal phase is always ____ days from ovulation to end of cycle

A

14 days

35
Q

ovarian cycle

A

Primordial into Primary (cubodiol)

Primary into secondary (multiple layers now surround the follicle

Early follicle : clear liquid starts to accumulate between the granular cells, continually accumulates and expands. liquid that accumulates in the antrum.

Liquid expands pushes oocyte to edge of ovary and ovulation occurs
the rupture follicle that remains (corpus luteum) fills up with blood and becomes a gland (secretes estrogen and progestron)

36
Q

During the follicular phase the hypothalamus releases more

A

Gnrh and Lh for sex hormone production

37
Q

During the follicular phase, the cells will become ______ and then ____

A

androgens, (male sex but converted into Estrogens)

38
Q

Fertilization occurs in

A

fallopian tube, and implants in uterus

39
Q

In fertilization the secondary oocyte completes

A

meosis 2

40
Q

Placenta is composed of

A

maternal and embryonic tissue

41
Q

the placenta secretes

A

estrogen and progesterone

42
Q

If fertilzation does not occur

A

progesterone and estrogen levels drop

and menstruation occurs

43
Q

3 phases of uterine cycle

A

menstrual (endometrium is shed)
proliferative (endometrium is rebuilt)
secretory (after ovulation, enrichment of blood supply and secretion of nutrients)
