Lesson Worksheet: The Menstrual Cycle Biology

In this worksheet, we will practice describing the roles of hormones in controlling the menstrual cycle and explaining how they interact with each other.

Q1:

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

  • AEstrogen
  • BProgesterone
  • CFSH (follicle-stimulating hormone)
  • DLH (luteinizing hormone)

Q2:

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

  • AEstrogen
  • BFSH (follicle-stimulating hormone)
  • CProgesterone
  • DLH (luteinizing hormone)

Q3:

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

  • AEstrogen
  • BProgesterone
  • CFSH (follicle-stimulating hormone)
  • DLH (luteinizing hormone)

Q4:

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

  • AFSH (follicle-stimulating hormone)
  • BProgesterone
  • CEstrogen
  • DLH (luteinizing hormone)

Q5:

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

  • ASo the uterus lining can be broken down during menstruation
  • BSo multiple eggs can be released from the ovaries
  • CSo only one egg is released from the ovaries
  • DSo FSH can be produced and can stimulate the egg to mature

Q6:

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

  • ALH (luteinizing hormone)
  • BEstrogen
  • CFSH (follicle-stimulating hormone)
  • DProgesterone
  • EAdrenaline

Q7:

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?

  • ADays 6–10
  • BDays 12–16
  • CDays 0–5
  • DDays 24–28
  • EA pregnancy is equally likely all of the time.

Q8:

The diagram provided shows the changes in the lining of the uterus wall over a typical 28-day cycle.

What hormone maintains the uterine lining between days 14 and 28?

  • AFSH
  • BLH
  • CProgesterone
  • DEstrogen

The menstrual cycle begins with the breakdown and shedding of the uterine lining. What scientific term is given to this event?

  • AFollicular maturation
  • BOvulation
  • CUterine breakdown
  • DMenstruation

Around day 14, an egg ready for fertilization is released from the ovaries. What scientific term is given to this event?

  • AOvarian secretion
  • BOvulation
  • CFollicular maturation
  • DMenstruation

Q9:

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?

  • AThickening of the uterine lining
  • BMenstruation
  • COvulation
  • DFollicle maturation

Why do the levels of estrogen peak just before day 14?

  • ATo stimulate the production of LH
  • BTo release an egg from the ovaries (ovulation)
  • CTo ensure the uterine lining is ready to be broken down
  • DTo stimulate the production of FSH

When is progesterone the highest and why?

  • ABetween ovulation and menstruation, to stimulate the maturation of an egg
  • BBetween menstruation and ovulation, to rebuild the uterine lining
  • CBetween ovulation and menstruation, to maintain the uterine lining
  • DBetween menstruation and ovulation, to stimulate the maturation of an egg

Q10:

Complete the table to describe some key events that take place in a typical 28-day menstrual cycle.

Day(s)0–5 5–14 14
Event
  • AUterine lining builds up, ovulation, menstruation
  • BMenstruation, ovulation, uterine lining builds up
  • COvulation, uterine lining builds up, menstruation
  • DMenstruation, uterine lining builds up, ovulation
