What effect does luteinizing hormone uterine (fallopian) tubes is called the (LH) have on a female?
- A. LH promotes enlargement of
- B. body the female's breasts.
- C. fundus
- D. LH has no effect on a femal
Correct Answer: D
Rationale: Rationale:
1. LH is a hormone released by the pituitary gland.
2. Its main role in females is to trigger ovulation.
3. LH does not directly affect the uterine tubes or breast enlargement.
4. Therefore, the correct answer is D: "LH has no effect on a female."
Summary:
A, B, and C are incorrect because LH does not promote breast enlargement or affect the uterine tubes. The correct answer, D, is supported by the physiological functions of LH in the female reproductive system.

The female reproductive system includes the following structures:
- A. ovary;
- B. Fallopian tubes;
- C. vagina;
- D. vulva;
Correct Answer: A
Rationale: The correct answer is A: ovary. The female reproductive system includes the ovaries, which are responsible for producing eggs and hormones like estrogen and progesterone. The Fallopian tubes are passageways for eggs to travel from the ovaries to the uterus, not a part of the system itself. The vagina is the birth canal and where sperm enters during intercourse, but it is not a reproductive organ. The vulva includes external genitalia like the labia and clitoris, but it is not a reproductive structure. Therefore, the ovary is the only structure directly involved in the reproductive process.
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.
Which of the following is NOT a sexually transmitted disease?
- A. Syphilis
- B. Gonorrhea
- C. Cough
- D. Genital Warts
Correct Answer: C
Rationale: The correct answer is C: Cough. Sexually transmitted diseases (STDs) are transmitted through sexual activity, not through coughing. Syphilis (A), Gonorrhea (B), and Genital Warts (D) are all STDs that are transmitted through sexual contact. Cough (C) is not a sexually transmitted disease as it is typically spread through respiratory droplets. Therefore, C is the correct answer as it does not fit the criteria of being an STD.
Which of the following is suitable for the fertilization of an egg?
- A. Sperm
- B. Spermatid
- C. Primary spermatocyte
- D. Spermatogonium
Correct Answer: A
Rationale: The correct answer is A: Sperm. Sperm is the mature male reproductive cell capable of fertilizing an egg. It carries genetic material and is designed for the process of fertilization. Spermatid (B) is an immature sperm cell not yet capable of fertilizing an egg. Primary spermatocyte (C) is a cell undergoing meiosis to produce spermatids. Spermatogonium (D) is a stem cell that gives rise to spermatocytes but is not directly involved in fertilization. Therefore, only sperm (A) is suitable for fertilizing an egg.
Where does the epididymis direct sperm cells into?
- A. vas efferens
- B. vas deferens
- C. rete testis
- D. prostate gland
Correct Answer: B
Rationale: The epididymis directs sperm cells into the vas deferens. Sperm mature in the epididymis and are stored there until ejaculation. The vas deferens then carries the mature sperm from the epididymis to the urethra for ejaculation. The other choices are incorrect because the vas efferens carries sperm from the rete testis to the epididymis, the rete testis is a network of tubules where sperm is collected from the seminiferous tubules, and the prostate gland secretes fluids that contribute to semen but does not direct sperm flow.
