The vagina is inserted on the:
- A. uterine corpus;
- B. uterine cervix;
- C. Fallopian tube;
- D. cervix
Correct Answer: D
Rationale: The correct answer is D: cervix. The vagina is inserted on the cervix, which is the lower part of the uterus that connects the uterus to the vagina. The cervix serves as a passageway for sperm to enter the uterus and for menstrual blood to exit. The other choices (A: uterine corpus, B: uterine cervix, C: Fallopian tube) are incorrect because they do not accurately describe the anatomical structure where the vagina is inserted. It is essential to understand the specific anatomical relationships to identify the correct answer.

Which of the following is the male pattern of development “master switch” gene?
- A. SRY
- B. MIS
- C. XYY
- D. XXY
Correct Answer: A
Rationale: The correct answer is A: SRY. The Sex-determining Region Y (SRY) gene is the master switch for male development. It initiates the development of male gonads. Choice B, MIS, is a hormone involved in female reproductive development. Choices C and D, XYY and XXY, are genetic conditions related to male chromosomal variations and are not the master switch gene for male development.
When men age, what is the effect of prostate gland enlargement?
- A. It compromises the ability to fertilize ova
- B. It compromises erectile function
- C. It compromises urination
- D. It compromises sperm production
Correct Answer: C
Rationale: Prostate gland enlargement commonly affects urination by obstructing the urethra.
Seminiferous tubules are lined with:
- A. Oocytes
- B. red blood cells
- C. Leydig cells
- D. Sertoli cells
Correct Answer: D
Rationale: The correct answer is D: Sertoli cells. Seminiferous tubules are lined with Sertoli cells, which provide structural support and nourishment to developing sperm cells. These cells also help in the process of spermatogenesis.
A: Oocytes are female germ cells found in the ovaries, not in the seminiferous tubules.
B: Red blood cells are not found in the seminiferous tubules. They are responsible for carrying oxygen in the bloodstream.
C: Leydig cells are found in the interstitial tissue of the testes and are responsible for producing testosterone, not lining the seminiferous tubules.
Therefore, the correct choice is D as Sertoli cells play a crucial role in sperm production within the seminiferous tubules.
A nurse teaches a male client how to perform a testicular self-exam in an effort to identify lumps that may be present in the testes. What does the nurse teach the client regarding normal testes size?
- A. Both testes should be the same size
- B. One testis is usually larger than the other
- C. One testis usually has a lump; the other does not
- D. Both testes usually have lumps
Correct Answer: B
Rationale: It is normal for one testicle to be slightly larger than the other.
Which of the following is true about placenta?
- A. It produces the hormone hCG.
- B. It stimulates development of the follicle
- C. Implantation site for developing embryo.
- D. It stimulates development of corpus luteum
Correct Answer: A
Rationale: The correct answer is A: It produces the hormone hCG. The placenta is responsible for producing the hormone human chorionic gonadotropin (hCG), which is essential for maintaining pregnancy by supporting the corpus luteum to produce progesterone. This hormone is also detected in pregnancy tests.
Choice B is incorrect because the placenta does not stimulate development of the follicle; rather, it supports the corpus luteum. Choice C is incorrect as the implantation site for the developing embryo is the endometrium of the uterus, not the placenta itself. Choice D is incorrect because the placenta does not stimulate the development of the corpus luteum; instead, it supports its function through hCG production.
