The medullar area of the ovary contains:
- A. blood vessels;
- B. vegetative (autonomi
- C. nerve fibers;
- D. lymphatic vessels;
Correct Answer: A
Rationale: The correct answer is A: blood vessels. The medullar area of the ovary contains blood vessels to supply oxygen and nutrients to the ovarian tissue. This is essential for the nourishment and function of the ovary. Choice B, vegetative (autonomic) nerve fibers, is incorrect as the ovary primarily receives autonomic innervation from the sympathetic and parasympathetic nervous systems, which are not specifically located in the medullar area. Choice C, nerve fibers, is also incorrect as nerve fibers are mainly found in the ovarian cortex rather than the medulla. Choice D, lymphatic vessels, is incorrect as the lymphatic vessels are responsible for draining lymph fluid and are not typically located in the medullar area of the ovary.

As preparation for hysterectomy, Mrs. Washington is having radiation therapy for cancer of the uterus, stage IIa. To promote her self-care during recovery from irradiation, which of the following is correct?
- A. Extensive psychologic support is necessary
- B. Extensive physical care is necessary
- C. Instruction in skin care is a priority
- D. Dietary fiber and roughage should be increased
Correct Answer: C
Rationale: Proper skin care is crucial to manage and prevent radiation-induced skin reactions.
Reproduction defines the process of:
- A. perpetuation of living organisms;
- B. production of genetically identical individuals;
- C. fecundation of the spermatozoon by the ovule;
- D. production of individuals with the species characteristics
Correct Answer: D
Rationale: The correct answer is D because reproduction involves producing individuals with species-specific characteristics through genetic recombination. This ensures the continuation of the species by passing on unique traits to offspring. Choice A is incorrect because reproduction is not just about perpetuating life but also involves creating new individuals. Choice B is incorrect as reproduction typically leads to genetic variation among offspring. Choice C is incorrect as it specifically refers to the fertilization process, which is just one part of reproduction and does not encompass the whole process of creating new individuals with species-specific traits.
Which of the following hormone stimulates the development of corpus luteum?
- A. Estrogen
- B. Progesterone
- C. Luteinizing hormone (LH)
- D. Follicle stimulating hormone (FSH)
Correct Answer: C
Rationale: The correct answer is C: Luteinizing hormone (LH). LH is responsible for stimulating the development of the corpus luteum after ovulation. It triggers the release of the egg from the follicle and promotes the transformation of the follicle into the corpus luteum, which is crucial for the production of progesterone. Estrogen (A) is involved in the development of the follicle, not the corpus luteum. Progesterone (B) is produced by the corpus luteum, not responsible for its development. FSH (D) is primarily involved in stimulating the growth of ovarian follicles, not the formation of the corpus luteum.
Mucous membrane partially or completely covering the vaginal orifice is called as:
- A. Clitoris
- B. Labia
- C. Hymen
- D. Vulva
Correct Answer: C
Rationale: The correct answer is C: Hymen. The hymen is a mucous membrane that partially or completely covers the vaginal orifice. It is a thin tissue located at the opening of the vagina. The hymen can vary in appearance and may partially cover the vaginal opening, making it an essential anatomical structure to consider. The other choices are incorrect because:
A: Clitoris - The clitoris is a highly sensitive sexual organ located above the vaginal opening, not covering it.
B: Labia - The labia are the folds of skin surrounding the vaginal opening, not covering it entirely.
D: Vulva - The vulva refers to the external female genitalia, including the labia, clitoris, and vaginal opening, but it does not specifically refer to the mucous membrane covering the vaginal orifice.
The hormone that is released from the testes is ______.
- A. Progesterone
- B. Vasopressin
- C. Testosterone
- D. None of the above
Correct Answer: C
Rationale: The correct answer is C: Testosterone. Testosterone is the primary male sex hormone produced by the testes. It plays a crucial role in the development of male reproductive tissues and secondary sexual characteristics. Progesterone (A) is a female sex hormone produced in the ovaries, not the testes. Vasopressin (B) is a hormone produced by the pituitary gland, not the testes. "None of the above" (D) is incorrect as testosterone is indeed released from the testes.
