Chapter 1 An Introduction to Anatomy and Physiology Review Questions Questions
Question 1 of 5
Identify a type of medical scan that places the radioactive material inside the body instead of hitting the body from the outside.
Correct Answer: D
Rationale: PET (positron emission tomography) uses internal radioactive tracers, unlike X-rays, CT, or MRI, which use external sources. Anatomical imaging benefits from PET's metabolic insight, confirming D.
Question 2 of 5
The varying conditions outside the human body are sometimes referred to as:
Correct Answer: B
Rationale: The external environment, denotes variable external conditions temperature, humidity unlike internal environment (A, body fluids), homeostasis (C, stability), disease, or set points (E, targets). Anatomically, it contrasts with the regulated internal milieu, influencing adaptation (e.g., sweating), confirming B.
Question 3 of 5
To which of the following does the 'tissue level' of structural organisation refer?
Correct Answer: D
Rationale: The tissue level groups cells into specialized types muscle for movement, nervous for signaling, connective for support, epithelial for covering forming the body's functional fabrics. Above cells and below organs, it's a critical organizational tier. Nurses study these to understand how tissues collaborate in health like muscle aiding mobility or falter in disease, such as epithelial breaches in ulcers. This level's diversity drives bodily complexity, distinguishing it from cellular components or organ-specific units.
Question 4 of 5
Which of the following is/are the contents of the ventral cavity?
Correct Answer: C
Rationale: The ventral cavity, spanning chest and abdomen, contains all internal organs or viscera like the heart, lungs, and digestive tract. This collective term captures its diverse occupants, vital for life's processes. Nurses monitor these for conditions like pneumonia affecting the thoracic or abdomino-pelvic zones, distinguishing them from dorsal contents. It's a broad anatomical category, guiding holistic care for the body's front-side systems.
Question 5 of 5
Which of the following correctly describes the two named body parts?
Correct Answer: B
Rationale: The phalanges, or finger bones, lie farther from the body's core than the carpals, or wrist bones, making them distal. This relationship aids nurses in hand assessments like fractures mapping limb anatomy accurately. Other pairs misalign: elbows are nearer than shoulders, ribs connect to the sternum, and elbows sit above knees. Precision here ensures effective care.
