1. Lowering the hand by straightening the elbow affects which of the following muscles?

• A. biceps brachii
• B. triceps brachii
• C. brachialis
• D. brachioradialis

Correct answer: B

Rationale: Lowering the hand by straightening the elbow is the action of extending the forearm, which is primarily done by the triceps brachii muscle. The triceps brachii is the main extensor muscle of the elbow joint. The biceps brachii is responsible for flexing the elbow, not extending it, making it an incorrect choice. Brachialis is a strong elbow flexor, and brachioradialis helps in flexing the elbow and pronating the forearm, so they are not the primary muscles involved in straightening the elbow.

2. 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.

3. 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.

4. Which of the following must the human body obtain from the environment in order to survive?

• A. Nitrogen
• B. Waste products
• C. Water
• D. Carbon dioxide

Correct answer: C

Rationale: The correct answer is C: Water. Water is essential for the human body to survive as it plays a crucial role in various physiological processes like digestion, circulation, and temperature regulation. Nitrogen is abundant in the atmosphere and is not directly obtained from the environment for survival. Waste products are materials that need to be eliminated from the body, not obtained for sustenance. Carbon dioxide is a byproduct of cellular respiration and is expelled from the body through breathing, not obtained as a nutrient.

5. Specialized cell types organized in a way that provides a specific function form

• A. tissues, which build organs.
• B. organs, which build tissues.
• C. organ systems, which build tissues.
• D. atoms, which comprise tissues.

Correct answer: A

Rationale: The correct answer is 'tissues, which build organs.' Specialized cell types organize to form tissues, which in turn build organs. Tissues are groups of cells that work together to perform a specific function. Option B is incorrect because organs are composed of tissues, not the other way around. Option C is incorrect as organ systems consist of multiple organs working together, not building tissues. Option D is incorrect as atoms are the basic building blocks of matter and are not directly involved in forming tissues.
