Hormones repeat

Goal

The goal of this lessonup is for you to practice with the hormones in the menstrual cycle.

Please use this as a way of checking the level of your knowledge. Don't click until you get it right (we can see how often you tried). Don't just copy from friends. Try to really figure out the correct answers for yourself so you will remember for next time.

Which structure is the main producer of these hormones?

Pituitary gland

Follicle

Corpus luteum

FSH

Progesterone

Oestrogen

LH

Which hormone, produced by the ovaries, stimulates the uterus lining to build up after menstruation?

1. Oestrogen
2. Progesterone
3. FSH
4. LH

Why does progesterone inhibit the release of LH after ovulation has occurred?

1. So the uterus lining can be broken down during menstruation
2. So multiple eggs can be released from the ovaries
3. So only one egg is released from the ovaries
4. So FSH can be produced and can stimulate the egg to mature

Which hormone, produced by the ovaries, maintains the lining of the uterus after ovulation?

1. Oestrogen
2. Progesterone
3. FSH
4. LH

Which hormone, released by the pituitary gland, stimulates ovulation?

1. Oestrogen
2. Progesterone
3. FSH
4. LH

Which hormone, released from the pituitary gland, stimulates the egg to mature?

1. Oestrogen
2. Progesterone
3. FSH
4. LH

Sperm can survive in the female reproductive system for around 4 days. Assuming a female is following a typical 28-day cycle, when would a pregnancy be most likely?

1. Days 6–10
2. Days 12–16
3. Days 0–5
4. Days 24–28

The diagram provided shows the changes in the hormones produced by the ovaries over a typical 28-day menstrual cycle. What event typically occurs between days 0 and 5?

1. Thickening of the uterus lining
2. Menstruation
3. Ovulation
4. Follicle maturation

The diagram provided shows the changes in the hormones produced by the ovaries over a typical 28-day menstrual cycle. Why do the levels of oestrogen peak just before day 14?

1. To stimulate the production of LH
2. To release an egg from the ovaries (ovulation)
3. To ensure the uterus lining is ready to be broken down
4. To stimulate the production of FSH

The diagram provided shows the changes in the hormones produced by the ovaries over a typical 28-day menstrual cycle. When is progesterone the highest and why?

1. Between ovulation and menstruation, to stimulate the maturation of an egg
2. Between menstruation and ovulation, to rebuild the uterus lining
3. Between ovulation and menstruation, to maintain the uterus lining
4. Between menstruation and ovulation, to stimulate the maturation of an egg

Which of the following is not a hormone that actively regulates the menstrual cycle?

1. Adrenaline
2. LH
3. Oestrogen
4. Progesterone

The diagram provided shows the changes in the lining of the uterus wall over a typical 28-day cycle. What hormone maintains the uterus lining between days 14 and 28?

1. FSH
2. LH
3. Oestrogen
4. Progesterone

The diagram provided shows the changes in the lining of the uterus wall over a typical 28-day cycle. The menstrual cycle begins with the breakdown and shedding of the uterus lining. What scientific term is given to this event?

1. Follicular maturation
2. Ovulation
3. Uterine breakdown
4. Menstruation

The diagram provided shows the changes in the lining of the uterus wall over a typical 28-day cycle. Around day 14, an egg ready for fertilisation is released from the ovaries. What scientific term is given to this event?

1. Ovarian secretion
2. Ovulation
3. Follicular maturation
4. Menstruation

Uterus lining builds up

ovulation

menstruation

Inhibits

Stimulates

Oestrogen (low concentration) --> FSH & LH production

Oestrogen (high concentration) --> FSH&LH production

Progesterone --> FSH & LH production

Oestrogen --> uterine lining

Progesterone --> uterine lining

What happens to the levels of oestrogen and progesterone during menstruation?

1. During menstruation, the levels of oestrogen and progesterone are low.
2. During menstruation, the levels of oestrogen are high and the levels of progesterone are low.
3. During menstruation, the levels of oestrogen are low and the levels of progesterone are high.
4. During menstruation, the levels of oestrogen and progesterone are high.

The diagram provided shows the changes in the concentrations of the pituitary gland hormones over a typical 28-day menstrual cycle. Why do the levels of LH peak on day 14?

1. To stimulate ovulation
2. To inhibit the production of progesterone
3. To encourage the uterus lining to break down
4. To stimulate the production of oestrogen

The diagram provided shows the changes in the concentrations of the pituitary gland hormones over a typical 28-day menstrual cycle. Which hormone increases in concentration after ovulation to keep the levels of both FSH and LH low?

1. Progesterone
2. Oestrogen

Increase of which pituitary hormone?

Increase of?

Peak of?

Increase of?

Decrease of?

FSH

Progesterone

Progesterone

LH

Oestrogen
