An Introduction to Anatomy and Physiology Review Questions Questions
Question 1 of 5
The region of the body that includes the head, neck, spinal column and ribs is the:
Correct Answer: B
Rationale: The axial portion includes head, neck, spine, and ribs, forming the body's core, unlike appendicular (A, limbs), pelvis (C, lower), or trunk (D, torso only). In anatomy, axial structures support central stability, distinguishing them from limb regions.
Question 2 of 5
The cavity that contains the pleural and abdominopelvic cavities is the ___ cavity.
Correct Answer: A
Rationale: The ventral cavity holds pleural (lungs) and abdominopelvic cavities, unlike dorsal (B, spine/brain), thoracic (C, chest only), or pericardial (D, heart-specific). In anatomy, ventral encompasses anterior cavities, organizing body spaces systematically.
Question 3 of 5
The posterior cavity is lined by three membranous layers called:
Correct Answer: C
Rationale: The dorsal (posterior) cavity's cranial and vertebral spaces are lined by meninges (dura, arachnoid, pia), not thoracic, mediastinum, or parietal (D, cavity lining type). Meninges protect the brain and spinal cord, a key anatomical feature.
Question 4 of 5
Most of the liver would be found in the ___ of the abdominopelvic cavity.
Correct Answer: C
Rationale: The liver predominantly lies in the right hypochondriac region (upper right), not lumbar (A, mid), iliac (B, lower left), or hypogastric (D, lower center). This anatomical mapping aids in clinical localization, like liver palpation.
Question 5 of 5
Identify the organ systems that function in integration and coordination?
Correct Answer: B
Rationale: Nervous (brain, nerves) and endocrine (hormones) systems coordinate body functions, unlike cardiovascular (A, C, circulation), or respiratory (D, breathing). Anatomy highlights their integrative roles e.g., stress response making B correct.
