Q

How does the functional layer regenerates each month? Describe what happens to this layer during menstruation include the hormones responsible for this

Q

Describe two factors that may impede the movement of the oocyte (or ovum if fertilised) in the uterine tubes

A
  • Infection in the uterine tubes due to pelvic inflammatory disease like chlamydia may lead to scar tissue in the uterine tube, this may narrow or block the uterine tubes causing sterility
  • Ectopic pregnancy may also result from cigarette smoking which reduces activity of cilia. This slows transport of the fertilised ovum to the uterus so it starts implant into the uterine tube

Q

Function of the perimetrium

A

Outer serous layer of the uterus. The serous layer secretes a lubricating fluid that helps to reduce friction.

27
Q

Describe the location of the cervix

A

Lowermost part of the uterus

28
Q

Name the hormone that causes the cervical mucus to become thinner and explain why this happens.

A

Becomes thin under the influence of oestrogen in mid-cycle allowing sperm to pass through the cervix

29
Q

Explain how cervical cancer can be prevented

A

Cervical smear test scrapes some of these epithelial cells which cover the tip of the cervix and examines them for abnormalities

30
Q

Describe the location of the vagina

A

Canal that extends from the cervix to the exterior, situated between the urethra & rectum.

31
Q

Name the two hormones involved in milk production and secretion

A
  • Prolactin

- Oxytocin

32
Q

State the stimulus for the secretion of follicle stimulating hormone (FSH) and luteinising hormone (LH)

A

Gonadotropin releasing hormone (GnRH) secreted by the hypothalamus stimulates the anterior pituitary gland to release follicle stimulating hormone and luteinising hormone

33
Q

Name the gland where FSH and LH are made and secreted from

A

Anterior pituitary gland

34
Q

What are the 4 phases of the reproductive cycle?

A
  • The menstrual phase (menstruation)
  • Pre-ovulatory phase
  • Ovulation
  • Post-ovulatory phase
35
Q

What days does the menstrual phase occur?

A

Days 1-5 (first day of bleeding is considered beginning of the 28 day cycle)

36
Q

What days does the Pre-ovulatory phase occur?

A

Days 6-13

37
Q

What days does the ovulation phase occur?

A

Day 14

38
Q

What days does the post-ovulatory phase occur?

A

Days 15-28

39
Q

What are the changes that occur with the menstrual phase?

A
  • Low levels of progesterone causes the spiral arterioles to constrict and the functional layer of the endometrium dies
  • The dead functional layer detaches from the uterine was causing 3-5 days of bleeding
    - 50 to 150ml of blood, tissue fluid and epithelial
    cells is shed from the endometrium
40
Q

What are the changes that occur with the pre-ovulatory phase?

A
  • Ovary: Development of mature follicle that enlarges and is ready for release from the ovary, production & release of oestrogen occurs
  • Uterus: creation of new functional layer to develop into the endometrium (with glands & spiral arteries growing into it)
41
Q

What are the changes that occur with the ovulation phase?

A
  • The ovarian follicle collapses and the follicular cells slowly begin to:
    - Enlarge and change character
    - Form the corpus luteum
  • The corpus luteum then secretes progesterone and oestrogen
42
Q

What are the changes that occur with the post-ovulation phase?

A
  • Ovary: Corpus luteum secretes oestrogen & progesterone. If secondary oocyte is not fertilized the corpus luteum becomes a corpus albicans (non-functional)
  • Uterus: oestrogen & progesterone promote thickening of the endometrium (in preparation for receiving the fertilised ovum). If fertilisation does not occur menstruation will begin a new cycle
43
Q

What hormone is dominant during the menstrual phase?

A

Decrease in progesterone

44
Q

What hormone is dominant during the pre-ovulation phase?

A

Increase in Oestrogen

45
Q

What hormone is dominant during the ovulation phase?

A

A surge in the level of LH

46
Q

What hormones is dominant during the post-ovulation phase?

A

Increase in oestrogen and progesterone

47
Q

State four signs of ovulation

A
  • Increase in basal body temperature
  • Cervical muscles thins and forms channels to allow sperm to pass through it - caused by rising oestrogen levels
  • Cervix softens
  • Discomfort/pain
48
Q

Describe the difference between the corpus luteum & corpus albicans

A
  • Corpus luteum is the hormone-secreting body formed immediately after ovulation from the opened follicle while corpus albicans is the white degenerated fibrous body.
49
Q

Describe the age related changes that occur during puberty and at menopause

A
  • Peak of reproductive abilities in late 20’s, after this, ovaries become less responsive to hormonal stimulation and ovarian function gradually declines
  • Ovulation and menstruation cease completely at age 46-64 years old (menopause). The ovaries continue to produce oestrogen for a while after menopause but then stop hormone production
50
Q

What would happen without sufficient oestrogen?

A
  • The reproductive organs and breasts atrophy
  • The vagina becomes dry
  • Weight gain
  • Loss of bone mass
  • Rising total blood cholesterol but decreased HDL levels
  • Hot flushes and sweating
  • Some women experience irritability and depression

Q

The mature (Graafian) follicle continues to enlarge and increase its oestrogen production during what stage?

Q

The open, funnel-shaped portion of a uterine tube is called the…

A

Infundibulum

59
Q

The basal layer of the endometrium of the uterus repeatedly gives what?

A

Repeatedly gives rise to a new functional layer after each menstruation

60
Q

A

Oestrogen
