1. Paired organs, such as the kidneys or lungs, are said to be
- A. bisexual.
- B. bilingual.
- C. bilateral.
- D. bivalent.
Correct answer: C
Rationale: The correct answer is C: 'bilateral.' Paired organs like the kidneys or lungs are described as bilateral because they occur in pairs on both sides of the body. Option A 'bisexual' refers to having both male and female reproductive organs, which is not the correct term for paired organs. Option B 'bilingual' refers to being able to speak two languages, which is not related to the description of paired organs. Option D 'bivalent' means having two valences, which is also unrelated to the context of paired organs.
2. Most of the terminology to name and describe body parts and their functions comes from
- A. Latin and Greek.
- B. English and Italian.
- C. Pictures drawn on the cave walls of our ancestors.
- D. The language of hunter-gatherers.
Correct answer: A
Rationale: The correct answer is Latin and Greek. Medical terminology is largely derived from Latin and Greek roots. These languages have been foundational in the development of medical terminology due to the precision and descriptive nature of their vocabulary. Choice B, English and Italian, is incorrect because while some medical terms may have originated from these languages, the majority come from Latin and Greek. Choices C and D, pictures drawn on the cave walls of our ancestors and the language of hunter-gatherers, are both incorrect as they do not align with the historical origins of medical terminology.
3. Which of the following is produced by the prostate gland?
- A. testosterone
- B. fluid to lubricate the head of the penis
- C. substance to enhance sperm mobility
- D. Gonadotrophin-releasing hormone
Correct answer: B
Rationale: The correct answer is 'fluid to lubricate the head of the penis.' The prostate gland produces a milky fluid that makes up part of the seminal fluid, which helps to nourish and transport sperm. Testosterone is produced mainly by the testes, not the prostate gland. While the prostate gland does contribute to sperm mobility, its primary function is to produce the fluid that lubricates the penis during ejaculation. Gonadotrophin-releasing hormone is produced by the hypothalamus and regulates the release of hormones from the pituitary gland.
4. Temperature is a form of energy, whereas heat is a measurement of the intensity of the temperature.
- A. TRUE
- B. FALSE
- C. Not Sure
- D. None of the above
Correct answer: A
Rationale: The statement is true. Temperature is a measure of the average kinetic energy of the particles in a substance, while heat is the transfer of energy from a hotter object to a colder one. Heat is not a measurement of the intensity of temperature, but rather the energy transfer due to a temperature difference. Therefore, the correct answer is True. Choice B (False) is incorrect as the statement is true based on the definitions of temperature and heat.
5. What is the most useful application of ultrasonography for diagnostic examination?
- A. dense organs, such as bones.
- B. air-filled organs, such as lungs.
- C. soft internal structures, such as fetuses.
- D. microscopic structures.
Correct answer: C
Rationale: Ultrasonography is a medical imaging technique that uses sound waves to visualize internal body structures. It is particularly effective for examining soft tissues like organs, blood vessels, and fetuses. Choice A is incorrect because bones are better visualized using techniques like X-rays. Choice B is incorrect as air-filled organs like lungs are not well visualized with ultrasound due to air being a poor conductor of sound waves. Choice D is incorrect since ultrasonography cannot visualize structures at a microscopic level, as it is used for larger internal structures.
