The semen contains liquids originating from:
- A. prostate;
- B. scrotum;
- C. seminal vesicles;
- D. epididymal duct;
Correct Answer: A
Rationale: Step-by-step rationale:
1. The prostate gland secretes a milky fluid that constitutes a major portion of semen.
2. This prostatic fluid contains enzymes, citric acid, and zinc, which nourish and protect sperm.
3. Seminal vesicles also contribute to semen production, but mainly by providing fructose for sperm energy.
4. The scrotum houses the testes but does not directly contribute fluids to semen.
5. The epididymal duct is a site for sperm maturation and storage but does not produce semen fluids.
Summary:
Choice A is correct because the prostate gland secretes a significant portion of semen. Choices B, C, and D are incorrect because they do not directly contribute fluids to semen production.

Immediately after birth, the baby was decribed as being a newborn or a/an ____________.
- A. obstetrician
- B. neonate
- C. antenatal
- D. foetus
Correct Answer: B
Rationale: The correct answer is B: neonate. A neonate refers to a newborn baby within the first 28 days of life. The term is commonly used in medical contexts to describe infants right after birth.
Rationale:
1. Obstetrician (Choice A): An obstetrician is a doctor who specializes in pregnancy, childbirth, and postpartum care. This term does not describe the baby itself.
2. Antenatal (Choice C): Antenatal refers to the period before birth, specifically during pregnancy. It does not describe the baby after birth.
3. Foetus (Choice D): A foetus is the term used for an unborn baby in the womb, not for a newborn baby after birth.
In summary, the term "neonate" is the correct choice as it specifically refers to a newborn baby immediately after birth, while the other options do not accurately describe the baby at this stage.
What is the first structure to receive the oocyte?
- A. fimbriae
- B. uterine tube
- C. infundibulum
- D. uterus
Correct Answer: A
Rationale: The correct answer is A: fimbriae. Fimbriae are finger-like projections at the end of the fallopian tube that capture the released oocyte from the ovary during ovulation. The fimbriae create a gentle sweeping motion to guide the oocyte into the uterine tube for fertilization. The other choices are incorrect because the oocyte needs to be captured by the fimbriae before entering the uterine tube, infundibulum, or uterus. The fimbriae are the initial structure responsible for receiving the oocyte, making choice A the correct answer.
Fertilization usually occurs in the nuclear division only. ______.
- A. Meiosis produces two
- B. ovary
- C. vesicular (Graafian) follicle
- D. Meiosis occurs in all cells of
Correct Answer: D
Rationale: The correct answer is D because meiosis occurs in all cells of the body. Meiosis is a specialized type of cell division that produces gametes (sperm and egg cells) with half the number of chromosomes. Fertilization, the fusion of sperm and egg, typically occurs after meiosis in the reproductive organs. Choices A, B, and C are incorrect because they do not directly relate to the process of fertilization or meiosis occurring in all cells. Choice A talks about the outcome of meiosis, choice B refers to a specific organ, and choice C mentions a stage in the development of an egg cell.
