- Q1
This hormone is released from the hypothalamus and stimulates cells in the anterior pituitary.
FSH
GnRH
LH
Estrogen
30s - Q2
What is the primary function of estrogen in females?
Regulate the menstrual cycle
Regulates the calcium level
Regulation of blood sugar levels
Regulation of cholesterol levels
30s - Q3
What is testosterone?
A psychological term that is only used by clinicians to determine one's risk of mental illnessSave Answer
A drug doctors give us to treat depression
a specific hormone is released by the hypothalamus which triggers the pituitary gland
A male hormone essential for sexual and reproductive development
30s - Q4
Why is progesterone important to the female body?
It aids in the development of the ovarian follicle.
It inhibits muscular contractions of the uterus that would result in the rejection of the adhering egg.
It causes the thickening of the endometrium to prepare the uterus for pregnancy.
It causes the egg cell to be released from the ovary.
30s - Q5
Which of the following is not related to estrogen function?
Influences the production of cervical mucous and the structure of the vaginal epithelium.
Encourages fluid depletion.
Assists in the maturation of the ovarian follicles.
Development of female secondary sex characteristics such as widening of the hips, growth of breasts, and uterus.
30s - Q6
Which hormones are released by the pituitary gland and play the central role in both male and female reproductive functions?
Testosterone and follicle-stimulating hormone
Luteinizing hormone and follicle-stimulating hormoneSave Answer
Progesterone and luteinizing hormone
Estrogen and testosterone
30s - Q7
What role does FSH play in the reproductive systems of both males and females?
FSH triggers ovulation in females while it promotes testosterone production in males.
FSH supports the development of ovarian follicles while stimulating the production of sperm cells in males.
FSH stimulates the production of estrogen in females while stimulating the production of sperm cells in males.
FSH regulates the thickening of endometrium in females while stimulating sperm production in males.
30s - Q8
Which of these events is NOT correctly matched with the time when it occurs?
LH surge - day 21
corpus luteum formed - days 14-26
beginning of menses - day 1
ovulation - day 14
30s - Q9
Which statement/s is/are TRUE about the menstrual cycle?
I. During menstruation, the entire endometrium is shed.
II. The menstrual cycle typically lasts 28 days for every individual.
III. In a normal menstrual cycle, ovulation would take place at day 7.
IV. The corpus luteum develops and produces progesterone around the 14th day of the menstrual cycle.
I and III
II, III, and IV
IV only
II and IV
30s - Q10
Arrange the following events from days 1 to 28 of the female reproductive cycle.
I. The endometrium regrows
II. The corpus luteum deteriorates
III. Ovulation takes place
IV. The endometrium breaks down
I, III, II, IV
II, IV, III, I
II, I, III, IV
IV, I, III, II
30s - Q11
Which of the following hormones is CORRECTLY matched?
FSH : maturation of egg ; LH : thickening of endometrium
FSH: ovulation; LH: maturation of egg
FSH: maturation of egg; LH: ovulation
FSH: thickening of endometrium; LH: ovulation
30s - Q12
Progesterone is one of the steroid hormones. It is secreted by the corpus luteum and by the placenta. Which of the following is the function of progesterone?
It prepares the uterus for possible pregnancy.
It causes the egg cells to be released from the ovary.
It causes the shedding of the uterine lining leading to menstruation.
It causes the development of the ovarian follicle.
30s - Q13
The cause of menses in the menstrual cycle is ______________.
increased estrogen secretion from the ovary, which stimulates the muscles of the uterus to contract.
decreased progesterone and estrogen secretion by the ovary.
increased progesterone production from the ovary, which produces blood clotting.
decreased production of oxytocin, causing the muscles of the uterus to relax.
30s - Q14
Which of the following represents the correct order of events during the menstrual cycle?
Luteal phase, menstruation, FSH rise, ovulation, follicular phase
FSH rise, ovulation, LH surge, luteal phase, menstruation
Menstruation, FSH rise, LH surge, ovulation, luteal phase
Follicular phase, luteal phase, FSH rise, ovulation, menstruation
30s - Q15
The feedback which is important for pregnancy to progress is __________.
After FSH has stimulated follicle development, negative feedback keeps FSH concentration low.
Estrogen stimulates the anterior pituitary gland to release LH and stimulates the ovary to release more estrogen.
LH stimulates the corpus luteum to develop, which produces progesterone. Progesterone inhibits the further release of LH.
FSH stimulates the ovary to release estrogen, but estrogen inhibits the production of FSH.
