Put the following structures in order to trace the journey of the egg from ovulation to release during menstruation: cervix, fallopian tube, ovary, uterus, vagina.
Ovary → Fallopian tube → Uterus → Cervix → Vagina
Ovary → Uterus → Fallopian tube → Cervix → Vagina
Ovary → Cervix → Uterus → Fallopian tube → Vagina
Ovary → Vagina → Cervix → Uterus → Fallopian tube
What are the two cycles called that the female body goes through each month?
Ovarian and uterine cycles
Respiratory and digestive cycles
Cardiac and pulmonary cycles
Renal and hepatic cycles
How often does the ovarian cycle occur?
Approximately every 28 days
Once a year
Every 7 days
Every 3 months
What is the word for an immature egg?
Oocyte
Zygote
Spermatozoon
Blastocyst
What is the term for “releasing the egg from the ovaries for fertilization”?
Ovulation
Menstruation
Implantation
Fertilization
What is the first phase of the ovarian cycle?
Follicular phase
Luteal phase
Ovulation
Menstrual phase
What is the “big idea” behind the first phase?
The follicles grow
The follicles shrink
The follicles disappear
The follicles remain unchanged
What is the second phase of the ovarian cycle?
Ovulation
Follicular phase
Luteal phase
Menstruation
What is the “big idea” behind the second phase?
One oocyte ruptures from the follicle
The follicle begins to form a new oocyte
Multiple oocytes are released at once
The follicle remains dormant
Which hormone spikes during the second phase of the ovarian cycle?
LH
FSH
Estrogen
Progesterone
Explain what exactly happens in the second phase of the ovarian cycle.
The spike in LH triggers an oocyte to rupture from the mature follicles into the fallopian tube. The oocyte lasts 24 hours (fertilization must occur during that window).
The uterine lining is shed and menstruation begins.
The corpus luteum degenerates and hormone levels drop.
The primary oocyte completes meiosis II and forms a zygote.
How long is an oocyte (egg) viable after ovulation?
12 to 24 hours
2 to 3 days
5 to 7 days
1 week
What is the third phase of the ovarian cycle? How long does it last?
Luteal phase
Follicular phase
Ovulation phase
Menstrual phase
What is the “big idea” behind the third phase?
The follicle turns into a corpus luteum
The egg is released from the ovary
The uterine lining is shed
The sperm fertilizes the egg
What is the corpus luteum? How is it formed?
The corpus luteum is a tiny endocrine gland that is formed after ovulation from the empty follicle.
The corpus luteum is a part of the fallopian tube that helps in fertilization.
The corpus luteum is a layer of cells that covers the ovary throughout the menstrual cycle.
The corpus luteum is a hormone secreted by the pituitary gland during ovulation.
What would happen if progesterone and estrogen levels did not trigger a drop in FSH and LH during the luteal phase?
A second ovulation could occur (while the body is already pregnant), leading to a second pregnancy.
Menstruation would occur immediately after ovulation.
The menstrual cycle would stop entirely.
The body would be unable to produce any hormones.
The third phase of the ovarian cycle is known as the ________.
follicular phase
ovulation
luteal phase
menstrual phase
Where is GnRH produced?
Hypothalamus
Pituitary gland
Thyroid gland
Adrenal gland
Where is FSH produced?
Pituitary gland
Thyroid gland
Adrenal gland
Pancreas
Where is LH produced?
Pituitary gland
Thyroid gland
Adrenal gland
Pancreas
Where is estrogen produced?
Corpus luteum
Pancreas
Thyroid gland
Adrenal medulla
Where is progesterone produced?
Corpus luteum
Adrenal medulla
Pancreas
Thyroid gland
Which hormone triggers the release of FSH and LH from the pituitary?
GnRH
Insulin
Thyroxine
Cortisol
Which hormone triggers follicles to grow, mature, and release estrogen?
FSH
LH
Progesterone
Testosterone
Which hormone triggers ovulation?
LH
FSH
Estrogen
Progesterone
What impact do the hormones produced by the corpus luteum have on the uterine lining? Why is this important?
They cause the uterine lining to thicken, preparing the endometrium for an embryo.
They cause the uterine lining to shed immediately, preventing implantation.
They thin the uterine lining, making it unsuitable for embryo attachment.
They have no effect on the uterine lining at all.
How often does the uterine cycle occur?
Approximately every 28 days
Once a year
Every 7 days
Every 3 months
What is the uterine cycle also known as?
Menstrual cycle
Ovarian cycle
Cardiac cycle
Respiratory cycle
What is occurring in the ovarian cycle during the menstrual phase of the uterine cycle?
Follicular phase (follicles are growing)
Luteal phase (corpus luteum is active)
Ovulation (release of the egg)
Corpus albicans formation
What is occurring in the ovarian cycle during the secretory phase of the uterine cycle?
The luteal phase
The follicular phase
Ovulation
Menstruation
What is the “big idea” behind the first phase?
Bleeding phase
Ovulation phase
Luteal phase
Follicular phase
The first phase of the uterine cycle is characterized by which of the following events?
Shedding of the endometrial lining
Ovulation
Thickening of the myometrium
Implantation of the embryo
What is the second phase of the uterine cycle? What days of the cycle is this phase?
Proliferative phase; days 4/5 → 14
Menstrual phase; days 1 → 4/5
Secretory phase; days 15 → 28
Ovulatory phase; day 14
What is the “big idea” behind the second phase?
Continue growth & vascularization to prepare for a fertilized egg
Initiate menstruation and shedding of the uterine lining
Trigger ovulation and release of the egg
Halt all hormonal activity in the reproductive system
The second phase of the uterine cycle is known as the ________.
menstrual phase
proliferative phase
secretory phase
