ATI Anatomy and Physiology Online Practice
1. 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: Latin and Greek.
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.
2. An investigator who conducts an experiment to determine how temperature changes affect the rate at which the heart beats is most likely a(n)
- A. anatomist.
- B. physiologist.
- C. chemist.
- D. biochemist.
Correct answer: physiologist.
Rationale: The correct answer is 'physiologist.' A physiologist studies how the body functions under normal and abnormal conditions, including how temperature changes can affect physiological processes like heart rate. An anatomist focuses on the structure of organisms rather than their functions, making choice A incorrect. Choices C and D are also incorrect as they are more related to the study of chemicals and biochemistry, which are not directly relevant to investigating the effects of temperature on heart rate.
3. Why are anatomy and physiology difficult to separate?
- A. Physiological functions depend on anatomical structures.
- B. Physiological functions in an organism are ongoing.
- C. Body parts provide structural support.
- D. Our understanding of physiology is changing more than our understanding of anatomy.
Correct answer: Physiological functions depend on anatomical structures.
Rationale: Anatomy and physiology are difficult to separate because physiological functions depend on anatomical structures. The correct answer highlights the interdependence between the two disciplines; physiological functions are carried out by anatomical structures. Choice B is incorrect as it only states a characteristic of physiological functions without addressing the relationship with anatomy. Choice C is incorrect as it talks about body parts providing structural support, which is not directly related to the interdependence of anatomy and physiology. Choice D is incorrect because the rate of change in understanding does not necessarily dictate the difficulty of separating the two disciplines.
4. The activities of an anatomist consist of ______, whereas those of a physiologist consist of _____.
- A. observing body parts; studying functions of body parts
- B. conducting experiments; making microscopic examinations
- C. studying molecules; observing forms of the body parts
- D. sketching; dissecting
Correct answer: observing body parts; studying functions of body parts
Rationale: An anatomist focuses on observing the structure and morphology of body parts, such as organs, tissues, and cells, to understand their organization. On the other hand, a physiologist is more concerned with studying the functions and processes of these body parts, including how they work individually and together to maintain homeostasis. Therefore, the correct answer is 'observing body parts; studying functions of body parts.' Choices B, C, and D are incorrect as they do not accurately reflect the primary activities of anatomists and physiologists.
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: the Greek word for 'cutting up.'
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.
