Menstruall Cycle

Question 1

What is the Menstrual Cycle

Answer 1

A 28 day cycle that prepares the female body for pregnancy, it consists of two interconnected cycles(Ovarian cycle and Uterine Cycle)

Question 2

What is the ovarian cycle

Answer 2

The Ovarian cycle controls the growth, maturation and release of an egg

Question 3

What are the phases of the ovarian cycle

Answer 3

1. Follicular phase(Day 1-14)
2. Ovulation(Day14)
3. Luteul Phase(15-28)

Question 4

What are the phases of the uterine cycle

Answer 4

1. Flow Phase(Days 1-5)-Period
2. Proliferative Phase (Days6-13)
   3.Ovulation(day 14)
3. Secretory Phase(15-28)

Question 5

Follicular Phase(Days 1-13)

Answer 5

FSH released by AP, that FSH stimulates follicles to mature and then estrogen is released. High levels of estrogen send negative feedback to AP but also cause sudden release of GnRH which stimulates the release of LH from AP and increase in LH trigger ovulation(Follicle bursts releasing an ovum)

Question 6

Ovulation phase(Day 14)

Answer 6

LH increase triggers the release of an ovum frrom the follicle into the oviduct(fallopian tube)

Question 7

Luteul Phase(15-28)

Answer 7

LH causes follicle to devlope into a corpus luteum which secretes progesterone. High levels of progesterone send feedback to AP to inhibit the FSH and LH production. Corpus luteum degenerates leading to low levels of progesterone, those low levels of the hormones in blood cause AP to increse secretiong of FSH and LH

Question 8

Menstrual Phase(days 1-5)

Answer 8

-Shedding the endometrium and egg(menstruation)

Question 9

Proliferative Phase(6-13)

Answer 9

-Estrogen from the growing follicle rebuilds the endometrium
-Development of follicles in ovary

Question 10

Ovulation(Day14)

Answer 10

Ovum is released and uterine lining continures to thicken(prepares for a possible implantation)

Question 11

Secretory Phase(Day15-28)

Answer 11

Corpus luteum forms and produces estrogen which thickens endometrium

Question 12

Endometrium

Answer 12

The endometrium is the inner lining of the uterus, and its main function is to support a fertilized egg and nurture early pregnancy.

Question 13

Ectopic pregnancy

Answer 13

When implantation happens somwhere that isnt the uterus

Question 14

What affects do estrogen and progestrone have on the endometrium

Answer 14

Estrogen thickens the endometrium and progesterone stabilizes the endometrium and prevents further shedding, if pregnancy doesnt occur estrogen and progesterone levels decrease leading to shedding of endometrium
