1. How many autosomes does a human primary spermatocyte have?

• A. 34
• B. 44
• C. 54
• D. 33

Correct answer: B

Rationale: A human primary spermatocyte has 44 autosomes. Autosomes are chromosomes that are not involved in determining an individual's sex. In humans, there are a total of 46 chromosomes in a somatic cell, with 22 pairs of autosomes and one pair of sex chromosomes. Therefore, the correct answer is 44 autosomes, making choice B the correct answer. Choices A, C, and D are incorrect as they do not represent the accurate number of autosomes in a human primary spermatocyte.

2. Which of the following is an example of an oviparous animal?

• A. Pigeon
• B. Elephant
• C. Sheep
• D. None of the above

Correct answer: A

Rationale: The correct answer is A: Pigeon. Oviparous animals are those that lay eggs, and pigeons fall under this category. Choice B, Elephant, is incorrect because elephants are viviparous, giving birth to live young. Choice C, Sheep, is also incorrect as sheep are viviparous animals. Choice D, None of the above, is not the correct answer as a pigeon is indeed an example of an oviparous animal.

3. Where does fertilization normally occur?

• A. Ampulla
• B. Interstitial portion
• C. Isthmus
• D. Infundibulum

Correct answer: A

Rationale: Fertilization typically occurs in the ampulla of the fallopian tube. The ampulla provides the ideal environment for fertilization due to the presence of cilia that help transport the egg and sperm, as well as the nourishing fluid within this region. The interstitial portion, isthmus, and infundibulum of the fallopian tube are not the primary sites for fertilization. The interstitial portion connects the fallopian tube to the uterine cavity, the isthmus is the narrowest part near the uterus, and the infundibulum is the funnel-shaped end near the ovary, where the egg is captured after ovulation.

4. Which of the following is used to differentiate abdominal mass from pelvic mass on clinical examination?

• A. Size
• B. Site
• C. Margins
• D. Lower border

Correct answer: D

Rationale: The lower border is used to differentiate between an abdominal mass and a pelvic mass during clinical examination. The lower border of the mass provides important information about its location and origin. The size (Choice A) alone may not always clearly distinguish between abdominal and pelvic masses. The site (Choice B) and margins (Choice C) are also important factors, but they are not as specific in differentiating between abdominal and pelvic masses as the lower border.

5. What is the definition of incomplete abortion?

• A. Part of the products of conception, especially the fetus, is expelled while the placenta and membranes are retained.
• B. All products of conception are expelled, and there is minimal per vaginal bleeding.
• C. The cervix is closed, and the products of conception remain in the uterus.
• D. The cervix dilates, and the products of conception are expelled.

Correct answer: A

Rationale: Incomplete abortion is defined as part of the products of conception, especially the fetus, being expelled while the placenta and membranes are retained. This is the correct definition, making option A the right choice. Option B is incorrect as it describes a complete abortion. Option C is incorrect because in incomplete abortion, the products of conception are not retained in the uterus, and the cervix may be open. Option D is incorrect as it describes a situation more likely to be seen in an inevitable abortion.
