25
Q

What is the function of the endometrium?

A

An exchange point of nutrients between the mother and the child

26
Q

What is found throughout the entire endometrium?

A

Blood vessels

27
Q

What does the endometrium look like?

A

The surface of the endometrium layer looks like protruding fingers

28
Q

What is the point of the finger-like surface on the endometrium

A

More surface area for the blood of the baby to have contact with the blood of the mother

29
Q

What is the myometrium made of?

A

Muscle tissue

30
Q

What is the function of the myometrium layer of the uterus?

A

The muscular layer contracts during birth

31
Q

What causes the contractions of the myometrium?

A

Oxytocin

32
Q

What are the functions of the perimetrium?

A

It is tough, rubbery and fibrous to support the uterus
It provides attachment points for ligaments to keep your uterus in place
It decreases the size of the endometrium after birth

33
Q

What is the cervix?

A

The opening from the vagina into the uterus

34
Q

What is found in the cervix?

A

Cervical mucus

35
Q

What happens to the cervical mucus when pregnancy occurs?

A

The cervical mucus hardens to become the cervical plug

36
Q

What happens over time to the cervix during pregnancy?

A

The cervix slowly relaxes

37
Q

What causes the cervix to relax?

A

A hormone is released when pregnant called relaxin

38
Q

How wide has the cervix dilated by the time of birth?

A

10 cm

39
Q

What causes cervical cancer?

A

Carcinogens and viruses (HPV) can get into the mucus of the cervix

40
Q

Describe the fallopian tubes

A

About 5 cm long
Smooth muscle layer
Lined with ciliated cells

41
Q

What is the function of a fallopian tube?

A

Carries the ovum down to uterus
The top third of the fallopian tube should be the site of fertilization
A pathway for sperm

42
Q

What is the function of the smooth muscle layer of the fallopian tube?

A

The smooth muscle undergoes peristalsis which moves the egg down the fallopian tube

43
Q

What is the function of the ciliated cells lining the fallopian tube?

A

The cilia beat rhythmically to create a current which helps move the egg down

44
Q

How long does it take an egg to move down the fallopian tube?

A

5 days

45
Q

Why does the ovum have to be fertilized in the top third of the fallopian tube?

A

It has to have enough time to develop and implant itself before menstruation

46
Q

Describe the ends of the fallopian tube closest to the ovary

A

The ends of the fallopian tubes are not directly attached to the ovaries, but instead have fingerlike extensions that catch the ovums leaving the ovary

47
Q

What are the fingerlike extensions of the fallopian tubes called?

A

Fimbriae (pl.)

48
Q

What is an ectopic pregnancy?

A

The egg implants itself in the wrong place (ex. Outside the uterus or in the fallopian tube)

49
Q

What is endometriosis?

A

When the endometrium cells move up the Fallopian tube and into the body cavity. The cells can attach to the outside of the uterus or other organs and go through the menstrual cycle.

50
Q

What is oogenesis?

A

The creation of the ovum

51
Q

How many follicles does each ovary contain?

A

200 000

52
Q

How many follicles are stimulated during each ovulation?

A

1000

53
Q

What pattern do the ovaries ovulate in?

A

They alternate during each ovulation (both don’t release egg cells at the same time)

54
Q

What is the oogonium?

A

A diploid egg cell

55
Q

What surrounds the oogonium?

A

Granulosa cells (nurse cells)

56
Q

What is a follicle made of?

A

Granulosa cells and an oogonium

57
Q

How many divisions does the oogonium go through?

A

2

58
Q

What is the resulting cells of the first division of the oogonium?

A

A haploid secondary oocyte and a polar body

59
Q

What is the resulting cells of the second division of the oogonium? (The division of the secondary oocyte)

A

An ootid and a polar body

60
Q

What does the ootid become?

A

An ovum
