LESSON 3.1

Menstrual cycle

Learning objectives

• I am familiar with the chronology of the menstrual cycle
• I am familiar with the key events of the menstrual cycle
• I can explain the role of the organs in the menstrual cycle
• I can explain the role of hormones in the menstrual cycle

Keywords

• menstrual cycle
• menstruation
• ovulation
• follicular phase
• luteal phase
• uterus 
• uterus lining / endometrium
• contractions
• ovary
• follicle
• estrogen
• progesterone

Menstrual cycle: a timeline

• 28 days on average
• day 1-day 4: menstruation: shedding of the uterus lining
• Follicular phase: between menstruation and ovulation
• around day 14: ovulation: bursting of follicle in the ovary
• most fertile period
• Luteal phase: between ovulation and menstruation

day 5-day 13: follicular phase

• Follicular phase: follicle grows and matures in ovary
• Ovulation: Ripe follicle bursts and ovum is released
• Ovulation is triggered by a hormone (LH)
• Estrogen causes the uterus lining to grow thicker

day 14-day 28: luteal phase

• luteal phase: uterus prepares for implantation (lesson 3.2)
• progesterone: causes the uterus lining to get more glands and more blood vessels
• remnant of the follicle in ovary is producing the progesterone
• this remnant is called: corpus luteum / yellow body
• menstruation is caused by a LACK of progesterone 
• corpus luteum is degenerating
