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
Name the phases involved in ovarian cycle.
Follicular phase
and Secretory phase
Follicular phase
and Luteal phase
Proliferative phase
Secretory phase
Follicular phase and Proliferative phase
During oogenesis, what occurs during the conversion of oogonium into primary oocyte?
Mitosis
Meiosis II
Meiosis I
Mitosis & Differentiation
In a 28 day cycle, on which day does process ovulation normally occur?
12
14
15
17
Which of the following is TRUE about ovulation?
Release ovum from the ovary
Stimulated by minimun release of LH
Inhibits production of corpus luteum
Releases secondary oocyte from ovary
What are the changes that would take place to structure corpus luteum if fertilization occurs?
Corpus luteum disintegrates
Corpus luteum maintain to secrete progesterone and estrogen.
Corpus luteum maintain and levels of progesterone and estrogen decline
Why the blood levels of FSH and LH increase if the ovaries are removed or after menopause? Choose the wrong answer.
When ovaries are removed, the levels of estrogen and progesterone decline
Cancelling the effect of negative feedback on FSH and LH
Causing the FSH and LH secretion to increase
Corpus luteum in the ovaries release estrogen and progesterone which have positive feedback on FSH and LH
Based on FIGURE above, which phase (s) involved positive feedback mechanisms?
1
2
3
1 and 3
Based on FIGURE above, which phase (s) involved negative feedback mechanisms?
1
2
3
1 and 3
Arrange the stages of fertilization:
1.Fusion of sperm head membrane and oocyte
2.Cortical reaction
3.Acrosomal reaction
4.Capacitation
4,2,3 and 1
4,3,1 and 2
2,4,1 and 3
4,3, 2 and 1
Choose the phases of menstrual cycle.
menstrual flow phase and luteal phase
follicular phase and luteal phase
menstrual flow phase, proliferative phase and secretory phase
follicular phase, ovulation and luteal phase
Which is not the function of LH?
induce final maturation of follicle
induces ovulation
stimulate formation of corpus luteum
disintegration of endometrium lining
If fertilization occurs corpus luteum will remain and secrete which hormone?
FSH
FSH and LH
estrogen
Estrogen and progesterone
What happens in fertilization to prevent polyspermy?
capacitation
acrosomal reaction
cortical reaction
release of hydrolytic enzyme
