Nokea
Which of the following cells could be fertilized?
- A. Polar body
- B. Primary oocyte
- C. Secondary oocyte
- D. Oogonium
Correct Answer: C
Rationale: The correct answer is C: Secondary oocyte. After meiosis I, the primary oocyte forms a secondary oocyte. The secondary oocyte is the cell that can be fertilized by a sperm to form a zygote. Polar bodies are products of oogenesis that do not participate in fertilization. Oogonium is a primordial germ cell in the ovary that undergoes mitosis to form primary oocytes. Therefore, the secondary oocyte is the only viable option for fertilization among the choices provided.

The testicle vascularization:
- A. the arterial one is provided by the gonadal artery, a branch off the abdominal aorta;
- B. the venous one is tributary to the internal iliac vein;
- C. the arterial one is provided by the testicular artery, a branch off the internal iliac artery;
- D. the venous one is tributary to the inferior vena cava;
Correct Answer: A
Rationale: The correct answer is A because the arterial vascularization of the testicle is indeed provided by the gonadal artery, which is a branch off the abdominal aorta. This is anatomically accurate as the gonadal artery supplies blood to the testicles.
Choice B is incorrect because the venous drainage of the testicle is to the testicular vein, which drains into the inferior vena cava, not the internal iliac vein as stated in option B.
Choice C is incorrect because the testicular artery, not the internal iliac artery, is responsible for the arterial supply to the testicle.
Choice D is incorrect because the venous drainage of the testicle is not tributary to the inferior vena cava; instead, it drains into the left renal vein.
The menstrual cycle is triggered each month by
- A. the release of blood from the uterus
- B. the buildup of the lining of the uterus
- C. hormones
- D. sexual intercourse
Correct Answer: C
Rationale: The correct answer is C: hormones. Hormones, specifically estrogen and progesterone, control the menstrual cycle by regulating the release of an egg from the ovary, thickening the uterine lining, and preparing the body for pregnancy or menstruation. Hormonal fluctuations throughout the cycle signal the body to shed the uterine lining if fertilization does not occur. Choices A and B are incorrect as they describe events during the menstrual cycle rather than the trigger itself. Choice D, sexual intercourse, does not directly trigger the menstrual cycle but may lead to conception, which is one of the outcomes of the menstrual cycle.

Rationale: Respecting her feelings acknowledges her emotional state and promotes trust.
Displacement of a bone form its joint is known as ____________________.
- A. Fracture
- B. Dislocation
- C. Displacement
- D. Sprain
Correct Answer: B
Rationale: Dislocation is the correct answer because it specifically refers to the displacement of a bone from its joint. A fracture (choice A) is a break in a bone, not a displacement. Choice C, displacement, is too general and does not specify the bone being out of a joint. A sprain (choice D) involves the stretching or tearing of ligaments, not the displacement of a bone. Therefore, dislocation is the most accurate term for the scenario described.
