MODULE 1 EXAM REVIEW Q&A
WITH RATIONALES
Master your first anatomy test with this ultimate Module 1
Exam Review bank, specifically engineered to mirror the
exact structure of Portage Learning assessments. Each high-
yield multiple-choice question includes direct, italicized answers
and detailed, bolded rationales that break down complex
terminology, directional planes, and feedback mechanisms.
Perfect for studying under secure proctor conditions like
LockDown Browser, this premium guide guarantees thorough
concept retention and high-scoring results.
1. Which of the following fields specifically
studies the structural relationships of body
parts without microscopic aid?
A) Cytology
B) Histology
C) Gross Anatomy
D) Systemic Physiology
Answer: C
Rationale: Gross anatomy examines
macroscopic structures that can be seen
with the naked eye. Cytology and histology
,require microscopes to view cells and
tissues.
2. Physiology is best defined as the study
of:
A) The physical structure of an organ
B) The chemical and physical functions of living
organisms
C) The evolutionary history of human bones
D) The microscopic layout of cellular
membranes
Answer: B
Rationale: Physiology focuses on how body
parts function and work together to support
life. Structure is the domain of anatomy.
3. Which principle states that an organ's
function is direct evidence of its structural
design?
A) Homeostatic equilibrium
B) Principle of Complementarity of Structure
and Function
C) Metabolic adaptation
D) Negative feedback loop
,Answer: B
Rationale: The principle of complementarity
dictates that function always reflects
structure; what a structure can do depends
on its specific functional form.
4. What is the correct hierarchical order of
structural organization from simplest to
most complex?
A) Cellular, Chemical, Tissue, Organ, Organ
System, Organism
B) Chemical, Cellular, Tissue, Organ, Organ
System, Organism
C) Chemical, Tissue, Cellular, Organ System,
Organ, Organism
D) Cellular, Tissue, Chemical, Organ,
Organism, Organ System
Answer: B
Rationale: The chemical level
(atoms/molecules) forms cells, which group
into tissues. Tissues form organs, organs
collaborate in systems, and systems
comprise the organism.
, 5. At which structural level does the
molecule DNA belong?
A) Cellular level
B) Tissue level
C) Chemical level
D) Organelle level
Answer: C
Rationale: Atoms and molecules, including
macromolecules like DNA, proteins, and
carbohydrates, comprise the chemical level
of organization.
6. A tissue is defined as a group of similar
______ working together to perform a
common function.
A) Organs
B) Molecules
C) Cells
D) Organelles
Answer: C
Rationale: Cells are the building blocks of
tissues. Tissues in turn combine to form
organs.
