• Reference: Unit 1 — Chapter 1: An Introduction to
Anatomy and Physiology
Stem: A student training as a nursing assistant notices
that a patient’s skin is thin, fragile, and easily bruised after
long-term corticosteroid use. The instructor explains that
the visible skin changes are related to deeper changes in
tissue structure and cell activity. Which statement best
reflects the relationship between anatomy and physiology
in this case?
Options:
A. Structure and function are independent, so the skin
,changes are unrelated to physiology.
B. Anatomy explains what the body looks like, while
physiology explains how altered structure affects function.
C. Physiology describes only disease, while anatomy
describes only normal tissues.
D. Anatomy applies only to gross structures, so skin
changes are not considered anatomical.
Correct Answer: B
Rationale — Correct Answer: The patient’s fragile skin
reflects a structural change that affects tissue function,
showing that anatomy and physiology are tightly linked.
Anatomy focuses on structure, while physiology explains
how that structure works and why a change in structure
can disrupt function.
Rationale — Incorrect Options:
A. Structure and function are not independent; the skin’s
appearance is directly related to tissue integrity and
function.
C. Both anatomy and physiology apply to normal and
abnormal states, not just disease.
D. Anatomy includes both gross and microscopic
structure, including skin and its layers.
Teaching Point: Structure changes often produce
predictable functional changes.

• Reference: Unit 1 — Chapter 1: An Introduction to
Anatomy and Physiology
Stem: A physical therapist explains to a patient that a torn
rotator cuff muscle may reduce shoulder movement
because the muscle cannot generate normal force. The
patient asks why a “structure problem” affects movement
so much. Which answer best fits an applied anatomy and
physiology explanation?
Options:
A. Muscles move bones because their structure is
specialized for contraction.
B. Bones move independently, and muscles only provide
warmth.
C. Movement is controlled by skin tension, not by muscle
structure.
D. Joint motion depends mainly on blood chemistry rather
than tissue structure.
Correct Answer: A
Rationale — Correct Answer: Skeletal muscles are
structurally specialized to shorten and generate force.
When the muscle is damaged, its ability to perform its
physiological function declines, which reduces movement
at the joint.
, Rationale — Incorrect Options:
B. Bones do not move independently; muscle contraction
drives most voluntary movement.
C. Skin contributes minimally to movement compared
with muscles, tendons, and joints.
D. Blood chemistry supports tissues, but it does not
directly produce joint motion.
Teaching Point: Muscle structure is designed for force
generation and movement.

• Reference: Unit 1 — Chapter 1: Levels of Organization
Stem: During a case conference, students trace how
oxygen moves from the lungs to working skeletal muscle
cells during exercise. The instructor asks which sequence
best represents the levels of organization involved in this
process. Which option is most accurate?
Options:
A. Organism → organ system → organ → tissue → cell →
chemical
B. Chemical → cell → tissue → organ → organ system →
organism
C. Cell → chemical → tissue → organ → organism → organ
system
