Nokea
Which structure provides a temporary
- A. seminal gland storage site for immature sperm?
- B. tunica albuginea
- C. ductus deferens
- D. ductus deferens
Correct Answer: A
Rationale: The correct answer is A, seminal gland, which provides a temporary storage site for immature sperm. Seminal glands are responsible for producing seminal fluid which nourishes and protects the sperm. The immature sperm are stored in the seminal gland until they mature. The other choices, B tunica albuginea, is a tough layer surrounding the testes, not involved in sperm storage. C ductus deferens is a tube that transports mature sperm from the epididymis to the urethra, not for storage of immature sperm. D is a duplicate of C, so it is incorrect.

Haversian canals are seen in
- A. Cortical bone
- B. Cancellous bone
- C. Spongy bone
- D. N/A
Correct Answer: A
Rationale: The correct answer is A: Cortical bone. Haversian canals are found in cortical bone, which is the dense outer layer of bone tissue. These canals contain blood vessels, nerves, and lymphatics, allowing for the exchange of nutrients and waste products. Cancellous bone (B) is spongy bone with a network of trabeculae and does not contain Haversian canals. Spongy bone (C) is a type of bone tissue with a porous structure but lacks the organized Haversian system seen in cortical bone. "N/A" (D) is not a valid option as it does not provide any relevant information.
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.
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.
Which gland produces thick, clear mucus that cleanses the penile urethra of acidic urine?
- A. Testes
- B. Seminal vesicles
- C. Prostate
- D. Bulbourethral glands
Correct Answer: D
Rationale: The correct answer is D: Bulbourethral glands. These glands produce thick, clear mucus that cleanses the penile urethra of acidic urine before ejaculation. This mucus helps neutralize the acidity of urine, creating a more hospitable environment for sperm to travel through. The other choices are incorrect because:
A: Testes produce sperm, not mucus.
B: Seminal vesicles produce a fluid rich in fructose to nourish sperm.
C: Prostate produces a milky fluid that aids in sperm motility.
The medical term expressing suture of the neck of the uterus is __________
- A. cervicography
- B. perineorrhaphy
- C. cervicorrhapy
- D. cervicorrhexis
Correct Answer: C
Rationale: The correct answer is C: cervicorrhaphy. "Cervico-" refers to the neck of the uterus, and "-rrhaphy" means suture. Therefore, cervicorrhaphy is the correct term for the procedure of suturing the neck of the uterus.
A: Cervicography is a diagnostic imaging technique, not a procedure for suturing.
B: Perineorrhaphy involves suturing the perineum, not the neck of the uterus.
D: Cervicorrhexis refers to cutting or incising the neck of the uterus, not suturing it.
