Q

The menstrual phase occurs on what days and is characterized by..

A

Days 1-5. Characterized by bleeding and sloughing as the corpus luteum regresses and a decrease in ovarian hormones occurs.

Q

Hormone that is from the pituitary gland, responsible for the ripening of the graafian follicle, stimulates the ovarian follicles, promotes follicular maturation in the secretion of estrogen

Q

Hormone that comes from the pituitary gland, stimulates the final ripening of the ovarian follicle, the ovary secretion of progesterone, the rupture to release the egg, the conversion of the ruptured follicle into a corpus luteum

Q

Where is estrogen produced

Q

Which three hormones are necessary for follicle growth

A

FSH, LH, and estrogen

20
Q

List functions or effects of estrogen

A

1) growth of ovaries and follicles
2) sensitizes the muscle to induce contractions of the Fallopian tubes
3) stimulates myometrial growth, cervical mucus secretion
4) growth and maintenance of epithelial surfaces and reproductive tract
5) growth of external genitalia
6) breasts- specifically duct growth
7) responsible for female body contours
8) sex drive and behavior
9) H20 retention
10) peaks slightly before ovulation causing an LH surge

21
Q

This hormone is produced by the corpus luteum and will decrease if the ovum is not fertilized

A

Progesterone

22
Q

List causes of progesterone

A

1) increase basal body temperature
2) induces secretory activity in the endometrium
3) prepares the uterus for the ovum (maturation of endo)
4) affects appetite
5) breast changes
6) inhibits the secretion of LH blocking LH surge in ovulation

23
Q

A decrease in which two hormones causes the degeneration of the endometrial lining and subsequent menstruation

A

Estrogen and progesterone

24
Q

The decrease in which hormone re-initiates the cycle

A

Ovarian hormone

25
Q

Androgens are produced by what

A

The ovary and adrenal gland

26
Q

List the two types of androgens and what they are responsible for

A 
1) testosterone 2) aldosterone
Both responsible for 
-male pattern hair growth
- cycle irregularity
- deepening of the voice
27
Q

Series of hormonal changes or reactions involving the hypothalamus, anterior pituitary gland, ovaries, uterus, uterine tubes, vagina and memory glands which All prepare the system for pregnancy, this is also known as the

A

Hypothalamic- pituitary- ovarian axis

28
Q

Which hormone stimulates the release of FSH and where does it come from

A

Follicle-stimulating hormone releasing factor (FSHRF). The hypothalamus

29
Q

What hormone stimulates the release of LH and where does it come from you

A

Luteinizing hormone releasing factor (LHRF). The hypothalamus

30
Q

List all hormones that are released from the ovary

A

Estrogen, progesterone and androgens

31
Q

Which hormone is responsible for ovulation

A

LH

32
Q

When does progesterone reach its peak

A

About seven days post ovulation

33
Q

As progesterone increases, LH will

A

Decrease

34
Q

As estrogen increases, LH will

A

Increase

35
Q

If the ovum is not fertilized the corpus luteum will regress at what day

A

22

36
Q

If the ovum is not fertilized progesterone levels will

A

Decrease

37
Q

If the ovum is not fertilized the Endo will

A

Slough off resulting in menstruation

38
Q

List characteristics if the ovum is fertilized

A

1) Stimulates development of the alveolar system
2) desensitizes the myometrium
3) inhibits cervical gland secretions
4) decreases immune response and uterine contractility

39
Q

The ovarian cycle is divided into what two portions

A

The follicular phase and the luteal phase

40
Q

Which day does follicular phase occur

A

1-14

41
Q

Which days does the luteal phase occur

A

15-28

42
Q

What occurs during the follicular phase

A

The follicular cells are stimulated by FSH and one or more follicles develop

43
Q

What occurs during the luteal phase

A

Ruptured follicle converts into a corpus luteum and then corpus Albicans

44
Q

Females are born with approximately how many primordial follicles

A

200,000- 400,000

45
Q

Each primordial follicle is 1 —- surrounded by a thin layer of cells

A

Ovum
