Ovarian and Uterine Cycles Questions

During which phase of the ovarian cycle does a mature egg get released from the ovary?

• Follicular phase

• Ovulation phase

• Luteal phase

• Menstrual phase

If fertilization does not occur after ovulation, what happens to the corpus luteum?

• It becomes larger and releases more estrogen

• It degenerates and hormone levels drop

• It continues releasing progesterone indefinitely

• It turns into a new follicle

The main purpose of the follicular phase in the ovarian cycle is to:

• Prepare the uterus for implantation

• Release a mature egg into the fallopian tube

• Develop and mature an egg within the follicle

• Break down the endometrial lining

Which hormone triggers ovulation during the middle of the ovarian cycle?

• Estrogen

• Progesterone

• Follicle-Stimulating Hormone (FSH)

• Luteinizing Hormone (LH)

During the luteal phase, what hormone is primarily responsible for maintaining the uterine lining?

• FSH

• LH

• Estrogen

• Progesterone

Which phase of the uterine cycle corresponds to the shedding of the endometrial lining?

• Menstrual phase

• Proliferative phase

• Secretory phase

• Ovulatory phase

The proliferative phase of the uterine cycle happens when:

• The uterus prepares to receive a fertilized egg

• The lining of the uterus thickens under the influence of estrogen

• The corpus luteum degenerates

• The uterine lining breaks down and exits the body

If fertilization occurs, what prevents menstruation from happening?

• Continuous release of LH from the pituitary gland

• Human chorionic gonadotropin (hCG) maintains the corpus luteum

• A surge of FSH that sustains the endometrium

• Rapid decline of progesterone and estrogen

The ovarian and uterine cycles are synchronized mainly through the actions of which hormones?

• LH and FSH only

• Estrogen and progesterone only

• FSH, LH, estrogen, and progesterone

• Testosterone and estrogen

What best describes the relationship between the ovarian and uterine cycles?

• They occur independently and do not affect each other

• The ovarian cycle controls the release of an egg, while the uterine cycle prepares for possible implantation

• The uterine cycle triggers ovulation directly while the ovarian cycle thickens the endometrial lining

• Both cycles are only controlled by FSH
