1. 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.

2. What does magnetic resonance imaging use?

• A. X-rays.
• B. a radio antenna.
• C. radioisotopes.
• D. high-frequency sound waves.

Correct answer: D

Rationale: Magnetic resonance imaging (MRI) uses high-frequency sound waves to create detailed images of the inside of the body. X-rays (Choice A) use electromagnetic radiation, not sound waves, making it an incorrect choice. A radio antenna (Choice B) is used for communication, not for MRI imaging. Radioisotopes (Choice C) are used in nuclear medicine imaging techniques, not in MRI scans. Therefore, the correct answer is high-frequency sound waves (Choice D) as they are utilized in MRI technology to produce images.

3. The transition from a hunter-gatherer to an agricultural lifestyle greatly changed the types of diseases and injuries that early peoples suffered.

• A. True
• B. False
• C. Not Sure
• D. All of the above

Correct answer: A

Rationale: The correct answer is True. The transition from a hunter-gatherer to an agricultural lifestyle did indeed greatly change the types of diseases and injuries that early peoples suffered. With the shift to agriculture came increased sedentism, population density, and interaction with domesticated animals, leading to the emergence of new diseases and health challenges. Choice B is incorrect because the statement is true based on historical and archaeological evidence. Choice C is incorrect as there is historical data supporting the impact of this transition. Choice D is incorrect as it is not applicable since all options do not hold true in this context.

4. The thoracic cavity lies _____________ the abdominopelvic cavity.

• A. dorsal (posterior) to
• B. ventral (anterior) to
• C. superior to
• D. inferior to

Correct answer: C

Rationale: The correct answer is 'superior to.' The thoracic cavity is located above the abdominopelvic cavity, making it superior. The term 'dorsal (posterior) to' refers to the back side, 'ventral (anterior) to' indicates the front side, and 'inferior to' means below. In the context of body cavities, the thoracic cavity is positioned higher than the abdominopelvic cavity, making 'superior to' the most appropriate choice.

5. The origin of the term 'anatomy' is related to

• A. the Greek word for 'function.'
• B. the name of the first anatomist.
• C. the Greek word for 'cutting up.'
• D. the function of internal organs.

Correct answer: C

Rationale: The correct answer is C: the Greek word for 'cutting up.' The term 'anatomy' originates from the Greek words 'ana' (up) and 'temnein' (to cut), which means 'cutting up' or 'dissection.' This term refers to the process of dissecting bodies to study their structure. Choices A, B, and D are incorrect because 'anatomy' is not related to the Greek word for 'function,' the name of the first anatomist, or the function of internal organs, but rather to the act of cutting up for study and examination.
