Chapter 1 An Introduction to Anatomy and Physiology Review Questions Questions
Question 1 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 2 of 5
To what does the term 'hypochondriac' refer?
Correct Answer: B
Rationale: Hypochondriac names the abdominal zones below the rib cartilage, right and left, key for organ localization. Nurses palpate here for liver or spleen issues, using its anatomical meaning below cartilage' not psychological or structural defects. This precision aids diagnostics, mapping the body's layout for targeted care.
Question 3 of 5
What structure separates the thoracic cavity from the abdominal cavity?
Correct Answer: B
Rationale: The diaphragm, a muscular sheet, divides the thoracic cavity housing lungs from the abdominal cavity with digestive organs. Nurses assess its movement like in breathing issues ensuring this barrier maintains cavity integrity. Unlike mediastinal or peritoneal roles, it's the key separator, critical for respiratory and abdominal health.
Question 4 of 5
A group of cells with a common structure and function is an example of an?
Correct Answer: B
Rationale: A collection of cells sharing form and purpose like muscle cells contracting defines the tissue level. This tier, above organelles and below organs, organizes the body's functional units. Nurses assess tissues like epithelial damage in burns knowing their collective role drives system performance. This structural unity shapes health, bridging cellular and organ complexity for effective physiological outcomes.
Question 5 of 5
Which is not a serous membrane?
Correct Answer: D
Rationale: Serous membranes (A, C, E) line body cavities and secrete fluid (e.g., parietal peritoneum, visceral pleura, pericardium). Mesentery is a peritoneal fold, still serous-related. The mouth's lining is mucous membrane, secreting mucus, not serous fluid. Anatomically, serous reduces friction in cavities; mucous protects openings, making D the outlier.
