What is the similarity between spermatogenesis and oogenesis?
Both are processes of gametes formation in human.
Both produces one gamete per germ cell.
Timing of gamete release is any time in spermatogenesis and oogenesis
Based on FIGURE , Identify stages: S, Y and Z.
S = Primordial germ cell,
Y = Primary spermatocyte (2n),
Z = Secondary spermatocyte (n)
S = Spermatogonium,
Y = Primary spermatocyte (2n),
Z = Secondary spermatocyte (n)
S = Spermatogonium,
Y = Primary spermatocyte (n),
Z = Secondary spermatocyte (2n)
Based on FIGURE , Identify V, W and X.
V = Meiosis I
W = Meiosis II
X = Mitosis
V = Meiosis I
W = Mitosis
X = Meiosis II
V = Mitosis
W = Meiosis I
X = Meiosis II
V = Meiosis II
W = Mitosis
X = Meiosis I
Sexual reproduction is vital to the propagation of the Human race. Which of the following sequences represents the correct order of events in the formation of a human fetus?
Zygote → Blastocyst → Embryo → Fertilization
Fertilization → Zygote → Blastocyst → Embryo
Blastocyst → Embryo → Differentiation → Zygote
Fertilization → Growth → Differentiation → Zygote
Which of the following hormones inhibits contraction of uterus?
Cortisol
Oxytocin
Prostaglandin
Progesterone
Beginning with the flow phase, arrange the biochemical processes in the order in which they occur during the menstrual cycle:
J. FSH and LH stimulate the follicles to develop and the oocyte to produce estrogen.
K. A breakdown of corpus luteum causes progesterone levels to drop.
L. A spike in LH causes the follicle to rupture.
M. The endometrial lining breaks down and low levels of estrogen stimulate the pituitary to release FSH and LH.
N. Rising estrogen levels suppress FSH production and development of other follicles.
O. High progesterone levels maintain the endometrial lining of the uterus.
M → J → N → L → O → K
M → J → N → L → O → K
The diagram shows the development of the oocyte and the follicle during the menstrual cycle. Match stage #3 in the cycle with what hormones are at their highest and most active.
estrogen levels consistently rise
luteinizing hormone levels are high
progesterone levels are high
A client informs the nurse of a positive result form an early pregnancy test but wants to be sure that she is pregnant. Which response is the most appropriate for the nurse to make?
"Pregnancy can be detected 24-48 hours after conception, depending on the test"
"Pregnancy cannot be detected before 12 days after conception"
"Most early pregnancy tests are not reliable."
"Most pregnancy tests cannot differentiate between pregnancy and premenstrual hormone levels."
Pollination occurs when…….
pollen is transferred from the male to the female parts of flowers.
one of the male nuclei fuses with the egg cell to give rise to the zygote.
dispersal of the progeny to gain a foothold in new localities.
the seeds resume growth after dormancy.
Which of the following hormones is CORRECTLY paired with its function?
Prolactin – stimulates breast development at puberty
Oxytocin – stimulates uterine contractions during parturition
Luteinizing hormone – responsible for follicle development in an ovarian cycle
Progesterone – repairment of uterus endometrial wall
Which of the following statements is NOT TRUE about hormonal control during birth in humans?
The release of the prostaglandin hormone from the placenta is increased.
The level of progesterone in the blood is higher than that of estrogen.
The anterior lobe of the pituitary gland secretes prolactin.
The posterior lobe of the pituitary gland secretes oxytocin.
Why is it important that only one sperm enters the secondary oocyte?
To maintain the diploid condition with 2 sets of chromosomes (2n)
Fertilisation by several sperms will cause polyploidy which is fatal to human.
To avoid genetic variation.
To control activities in the cell.
Which of the following hormones stimulates ovulation and the development of the corpus luteum?
Estrogen
Progesterone
Luteinizing hormone
Follicle stimulating hormone

one every twenty-eight days.
one every fourteen days.
once every nine months.
twelve times a year.
