17
Q

Follicular phase

A

Increase size of follicle

Occurs before ovulation

Days 1-14
Includes pre-ovulatory phase

Most variable part of cycle

FSH stimulates follicles to grow and secrete estradiol

Q

What are the steps in the ovarian cycle

A
  1. Formation of primary, secondary, and tertiary follicles
  2. Ovulation
  3. Formation and degeneration of the corpus luteum

Corpus luteum begins to degenerate 12 days after ovulation if there is no fertilization (THIS PART WILL SHED)

  1. Degrading of corpus luteum
20
Q

How long is a normal cycle?

A

28 days

+/- 7 days

First day of menstration = first day of cycle

21
Q

How many eggs are female born with

A

2 million eggs

22
Q

Ovulation

A

Rupture of mature follicle and release of the ovum

Happens day 14

Estradiol stimulates a surge of LH and a smaller amount of FSH

LH stimulates primary oocyte completes meiosis I (MAKES SECONDARY OOCYTE)

23
Q

What are the parts of the uterine tubes

A

Infundibulum

Ampulla

Isthmus

24
Q

What are the other names for uterine tubes

A

Fallopian tubes

Oviductss

25
Q

Structure of infundibulum

A

End of infundibulum closest to the ovary has numerous fingerlike projections (THIS IS CALLED FIMBRIAE)

26
Q

What is the middle portion of the uterine tubes

A

Ampulla

27
Q

Structure of isthmus

A

A short segment connected to uterine wall

28
Q

Each uterine tube opens directly into

A

Uterine wall

29
Q

When does fertilization occur in the uterine tube

A

12-24 hours after ovulation

30
Q

What are the functions of the uterus

A

Mechanical protection

Nutritional support

Waste removal for the developing embryo and fetus

31
Q

List the layers of the uterine wall from outside to inside

A

Perimetrium

Myometrium

Endometrium

32
Q

Perimetrium

A

External serosa layer

33
Q

Myometrium

A

Middle muscular layer

Is majority of the uterine wall

Composed mainly of smooth muscle
Produces labor contractions, expels fetus

34
Q

Endometrium

A

Inner mucosa

Simple columnar epithelium

Has two layers: functional layer, and basal layer

35
Q

Functional layer (stratum functionalis)

A

Superficial half, shed each menstrual period

36
Q

Basal layer (stratum basalis)

A

Deep layer

Stays behind and regenerates a new stratum functionalis with each menstrual cycle

37
Q

What is the function of the endometrium during pregnancy?

A

Endometrium is the site of attachment of embryo

Forms the maternal part of the placenta from which the fetus is nourished

38
Q

What are the 3 phases of uterine cycle

A

Menses

Proliferative phase

Secretory phase

39
Q

Uterine cycle continues from _____ to ______

A

Uterine cycle continues from menarche (the first menstruation) to menopause (the last menstruation)

40
Q

Menes

A

Menstruation phase

Degeneration of the endometrium (SHEDS THIS LAYER)

Menstruation

41
Q

Proliferative phase

A

Restoration of the endometrium

42
Q

Secretory phase

A

Endometrial glands enlarge and accelerate their rates of secretion

43
Q

What do the hormones of the female reproductive cycle do

A

Control the reproductive cycle

Coordinate the ovarian and uterine cycles

44
Q

What does estradiol/estrogen stimulate in puberty

A

Stimulate growth of ovaries and secondary sex organs

Stimulates growth hormone secretion

(Height and widening of pelvis)

Stimulates fat deposition (breast and hips)

45
Q

What is the function of progesterone

A

Primarily act on uterus preparing it for pregnancy in second half of menstrual cycle

46
Q

Estrogens and progesterone suppress FSH and LH secretion through ____

A

Negative feedback

47
Q

Menopause

A

NO PROGESTERONE SECRETION

45-55 years old

Decline in circulating estrogen and progesterone

Rise in GnRH, FSH, LH
THIS IS BC ESTROGEN IS NO LONGER THERE TO STOP HORMONE SECRETION
