The normal site of fertilization is:
- A. the uterus
- B. the vagina
- C. the ureter
- D. the oviduct
Correct Answer: D
Rationale: The correct answer is D: the oviduct. Fertilization occurs in the oviduct, specifically in the ampulla region. Sperm meets the egg in the oviduct where fertilization takes place. The other choices, A: the uterus, B: the vagina, and C: the ureter, are incorrect because fertilization does not occur in these locations. The uterus is where the fertilized egg implants and develops into a fetus. The vagina is the passage for sperm to enter the reproductive system. The ureter is a tube that connects the kidney to the bladder, and is not involved in fertilization.

Cowper's gland is another name for:
- A. Prostate gland
- B. Testes
- C. Bulbourethral glands
- D. Preputial glands
Correct Answer: C
Rationale: The correct answer is C: Bulbourethral glands. Cowper's gland is another name for the bulbourethral glands, which are responsible for producing a lubricating fluid that helps neutralize acidity in the urethra before ejaculation. The prostate gland (A) is responsible for producing seminal fluid, the testes (B) are responsible for producing sperm, and the preputial glands (D) are glands found in the foreskin of the penis. Therefore, the bulbourethral glands (C) are the correct answer because they align with the function and location of Cowper's gland.
Which factor causes the act of ovulation?
- A. blood pressure
- B. LH levels
- C. FSH levels
- D. estrogen
Correct Answer: B
Rationale: The correct answer is B: LH levels. Ovulation is triggered by a surge in luteinizing hormone (LH) levels, which causes the release of the mature egg from the ovary. LH surge is a key event in the menstrual cycle that leads to ovulation.
Explanation:
1. LH surge stimulates the release of the egg from the dominant follicle in the ovary.
2. This surge typically occurs around the middle of the menstrual cycle.
3. Ovulation occurs within 24-36 hours after the LH surge.
4. FSH (Choice C) is involved in follicle development but does not directly cause ovulation.
5. Estrogen (Choice D) plays a role in the menstrual cycle but does not directly trigger ovulation.
6. Blood pressure (Choice A) is not involved in the process of ovulation.
Summary: LH levels are the primary factor that causes ovulation by triggering the release of the egg from the ovary
Between puberty and menopause, monthly, the following occurs :
- A. the maturation of a single secondary ovarian follicle;
- B. the transformation of a primordial follicle into a secondary one;
- C. the release of an oocyte;
- D. the release of a de Graaf follicle;
Correct Answer: C
Rationale: The correct answer is C: the release of an oocyte. During the menstrual cycle, ovulation occurs where a mature egg (oocyte) is released from the ovary. This typically happens around the middle of the cycle in response to hormonal changes. This process is essential for fertilization and pregnancy to occur.
A, B, and D are incorrect because:
A: the maturation of a single secondary ovarian follicle - This occurs before ovulation, not during the menstrual cycle.
B: the transformation of a primordial follicle into a secondary one - This is an earlier stage in follicle development, not a monthly occurrence.
D: the release of a de Graaf follicle - The Graafian follicle is the mature follicle that releases the oocyte during ovulation, not a monthly event.
