COMPLETE REAL EXAM QUESTION
. Where does fertilization typically occur?
A) In the uterus
B) In the outer one-third of the fallopian tube (ampulla)
C) In the cervix
D) In the ovary
Answer: B) In the outer one-third of the fallopian tube (ampulla)
Rationale: Fertilization usually occurs in the ampulla, the outer third of
the fallopian tube. The ovum is viable for approximately 24 hours after
ovulation, and sperm can survive up to 5 days in the female reproductive
tract.
2. What is the union of a single egg with a single sperm called?
A) Gametogenesis
B) Fertilization
C) Implantation
D) Meiosis
Answer: B) Fertilization
Rationale: Fertilization is the process by which a sperm cell unites with an
ovum to form a zygote. This process restores the diploid number of
chromosomes (46 total, 23 from each parent).
3. The process of cell division that results in gametes (sex cells) is called:
A) Mitosis
B) Meiosis
,C) Gametogenesis
D) Cleavage
Answer: B) Meiosis
Rationale: Meiosis is the specialized cell division process that produces
gametes (sperm and ova) with 23 chromosomes each. Gametogenesis is
the broader term for the formation of gametes, which includes meiosis.
4. Oogenesis results in the production of:
A) Sperm cells
B) Ova (egg cells)
C) Zygotes
D) Embryos
Answer: B) Ova (egg cells)
Rationale: Oogenesis is the process of female gamete formation. Females
are born with all their primary oocytes (approximately 1-2 million), and
only about 400-500 will mature and be released during a woman's
reproductive years.
5. When does implantation of the blastocyst typically occur?
A) 1-3 days after fertilization
B) 6-10 days after fertilization
C) 14 days after fertilization
D) 21 days after fertilization
Answer: B) 6-10 days after fertilization
Rationale: Implantation occurs when the blastocyst embeds into the
endometrial lining of the uterus, typically 6-10 days after fertilization.
This is when human chorionic gonadotropin (hCG) becomes detectable.
,6. What is the length of the embryonic stage of development?
A) Conception to Day 14
B) Days 15 through 8 weeks
C) Weeks 8 through 40
D) Weeks 12 through 40
Answer: B) Days 15 through 8 weeks
Rationale: The embryonic stage spans from approximately Day 15
through the 8th week of gestation. This is the period when major organs
and structures develop, making it the stage of greatest susceptibility to
teratogens. The fetal stage begins at 8-9 weeks.
7. Which of the following is TRUE about the embryonic stage?
A) The fetus is most susceptible to teratogens
B) The fetus begins to grow fingernails
C) The fetus reaches viability
D) The fetus can survive outside the uterus
Answer: A) The fetus is most susceptible to teratogens
Rationale: The embryonic stage (Days 15-8 weeks) is the period of
organogenesis. During this critical period, exposure to teratogens can
cause major structural birth defects. The fetal stage (weeks 8-40) is a
period of growth and maturation.
8. What develops by Day 14 of embryonic development?
A) The umbilical cord
B) The neural tube
C) The placenta
D) The amniotic sac
Answer: A) The umbilical cord
Rationale: The umbilical cord begins to develop by Day 14 of embryonic
development. It contains two arteries and one vein, surrounded by
, Wharton's jelly for protection. The structure is complete by
approximately 12 weeks.
9. By what point is circulation through the umbilical cord established?
A) Day 7
B) Day 10
C) Day 14
D) Day 17
Answer: D) Day 17
Rationale: Circulation and transfer of nutrients and waste through the
umbilical cord is established by Day 17. The umbilical cord contains two
arteries and one vein that connect the fetus to the placenta.
10. When does the placenta take over the endocrine function of the
corpus luteum?
A) 4 weeks of gestation
B) 6 weeks of gestation
C) 8-10 weeks of gestation
D) 12-14 weeks of gestation
Answer: C) 8-10 weeks of gestation
Rationale: The corpus luteum produces progesterone to maintain the
pregnancy until the placenta is mature enough to take over this function.
By approximately 10 weeks of gestation, the placenta has assumed the
endocrine role. If the placenta fails to take over, miscarriage may occur.
11. What are the three major functions of the placenta?
A) Endocrine, metabolic, and circulatory
B) Respiratory, digestive, and excretory
