20
Q

What is menopause?

A

When ovulation and menstruation stop happening in a female

21
Q

What is menstruation and when does it occur?

A

Menstruation is the discharge of the walls of the endometrium and unfetilised egg.
Occurs Days 1-5 of menstrual cycle

22
Q

What is the egg produced by ovulation surrounded in?

A

Graffian follicle

23
Q

What hormone does the graffian follicle produce after day 5?

24
Q

What are the roles of oestrogen in the menstrual cycle during days 6-14?

A

1.Prevent new eggs developing
2. Causes endometrium to thicken again
3. Causes production of LH

25
Q

How does ovulation occur on day 14?

A

The graffian follicle bursts and releases the egg from the ovary

26
Q

What happens to the remains of the graafian follicle during days 14 - 28

A

They develop into the corpus luteum

27
Q

What is the role of corpus luteum?

A

Makes the hormone protestorone

28
Q

What are the roles of progesterone?

A
  1. Cause the endometrium to thicken
  2. Prevent production of eggs
29
Q

What happens as a result of no fertilisation taking place during the menstrual cycle?

A

The corpus luteum degenerates which causes the endometrium to break down due to low progesterone levels

30
Q

Name a menstrual disorder, it’s cause and treatment

A

Disorder: Fibroids
Cause: abnormal response to oestrogen
Treatment: Large fibroids removed by surgery, small ones just get examined

31
Q

What hormones are produced by pituitary gland?

A

FSH and LH

32
Q

What hormones are produced by the graafian follicle?

Chemotaxis

38
Q

What are survival times for both egg and sperm

A

Egg: up to 2 days
Sperm: up to 7 days

39
Q

Define implantation

A

The embedding of a fertilised egg into the endometrium

40
Q

What happens at day 3 of zygote development

A

It forms a morula

41
Q

Define morula

A

A morula is a solid ball of cells formed from a zygote by mitosis

42
Q

What happens by day 5 of zygote development

A

The morula develops into a blastocyst

43
Q

What is a blastocyst?

A

A hollow ball of cells formed from a morula

44
Q

What event happens 10 days after fertilisation

A

Embryotic development (Germ layers form)

45
Q

What are the 3 layers of embryonic development

A
  1. Ectoderm
  2. Mesoderm
  3. Endoderm
46
Q

Define germ layers

A

Germ layers are basic levels of cells in the blastocyst from which all adult tissues and organs will form
