The __________________ is a thick, muscular organ that can expand to accommodate a developing baby.
- A. Uterus
- B. Ovary
- C. Vulva
- D. Breast
Correct Answer: A
Rationale: The correct answer is A: Uterus. The uterus is a thick, muscular organ located in the lower abdomen where a developing baby grows during pregnancy. It can expand significantly to accommodate the growth of the fetus. The ovaries (B) are responsible for producing eggs, not for accommodating a developing baby. The vulva (C) refers to the external female genitalia, not the organ that supports pregnancy. The breast (D) is responsible for producing milk after childbirth, not for housing a developing baby.

_______ is a lytic enzyme released by the sperm.
- A. Hyaluronidase
- B. Trypsin
- C. Helicase
- D. None of the above
Correct Answer: A
Rationale: The correct answer is A: Hyaluronidase. This enzyme is released by the sperm to help penetrate the outer layer of the egg during fertilization. Hyaluronidase specifically breaks down hyaluronic acid present in the cumulus cells surrounding the egg. Trypsin is a digestive enzyme found in the pancreas, not involved in sperm function. Helicase is an enzyme involved in DNA replication and repair, not released by sperm. "None of the above" is incorrect as hyaluronidase is indeed released by the sperm.
The deferent duct joins with the ........ and forms.........:
- A. the seminal vesicle duct;
- B. the urethra;
- C. the ejaculatory duct;
- D. the epididymal duct;
Correct Answer: C
Rationale: The correct answer is C: the ejaculatory duct. The deferent duct, also known as the vas deferens, joins with the seminal vesicle duct to form the ejaculatory duct. This is where sperm from the testes and fluid from the seminal vesicles combine before entering the urethra during ejaculation. The other choices are incorrect because the seminal vesicle duct does not directly join with the deferent duct, the urethra is not formed by the deferent duct, and the epididymal duct is not involved in the formation of the ejaculatory duct.
This tiny gland produces a secretion that is similar to a large lysosome and that cleanses the male urethra of assists penetration of the egg is called traces of acidic urine prior to the ________.
- A. flagellum
- B. prostate
- C. midpiece
- D. bulbo-urethral gland
Correct Answer: D
Rationale: The correct answer is D: bulbo-urethral gland. This gland produces a clear secretion that neutralizes traces of acidic urine, lubricates the urethra, and assists in sperm motility. The other choices are incorrect because:
A: Flagellum is a structure on sperm cells for propulsion.
B: Prostate produces seminal fluid but does not cleanse the urethra.
C: Midpiece is a part of the sperm cell that contains mitochondria for energy production, not a gland.
With respect to ejaculation which of the following statements is incorrect.
- A. ejaculation is the result of para-sympathetic stimulation
- B. ejaculation results from the summation of synaptic potentials
- C. during ejaculation semen is expelled by rapid contraction of the urethral smooth muscle
- D. ejaculation results is the discharge of sperm, seminal vesicle and prostatic secretions
Correct Answer: A
Rationale: The correct answer is A because ejaculation is primarily controlled by the sympathetic nervous system, not the para-sympathetic system. The sympathetic nervous system triggers the contraction of smooth muscles to allow for ejaculation. Choice B is incorrect because ejaculation is not a result of summation of synaptic potentials, but rather a coordinated response. Choice C is incorrect because semen is expelled by rhythmic contractions of the pelvic floor muscles, not the urethral smooth muscle. Choice D is incorrect because ejaculation involves the discharge of sperm, seminal vesicle, prostatic secretions, and other fluids from the reproductive system.
A client with the herpes simplex virus type 2 (HSV-2) undergoes a viral shedding. Which of the following statements is true when caring for a client with HSV-2?

- B. Clients don't seek treatment because of embarrassment.
- C. Healthcare providers and laboratories are not required by law to report.
- D. Reporting is up to the client, not the provider.
Correct Answer: A
Rationale: HSV-2 outbreaks are often self-limiting, though antiviral medications can help manage symptoms.
