1. Reference: Ch. 1 — The Body — Anatomical position and
directional terms
Stem: A patient is examined after a fall, and the clinician
documents the injury using standard anatomical
terminology. In anatomical position, the forearm is
supinated and the palms face forward. Which statement is
correct for the thumb and forearm in this position?
Options:
A. The thumb is medial and the radius lies posterior to the
ulna.
B. The thumb is lateral and the radius lies lateral to the
, ulna.
C. The thumb is posterior and the ulna lies lateral to the
radius.
D. The thumb is anterior and the radius crosses medially
over the ulna.
Correct Answer: B
Rationale — Correct Answer: In anatomical position, the
palms face anteriorly and the thumbs point laterally. The
radius is the lateral forearm bone in this position, while the
ulna is medial. This relationship is fundamental for
describing fractures, dislocations, and imaging findings
consistently.
Rationale — Incorrect Options:
A. The radius is not posterior to the ulna in anatomical
position; that relationship changes with forearm rotation.
C. The thumb is not posterior, and the ulna is medial rather
than lateral in anatomical position.
D. The thumb is not anterior, and the radius does not cross
medially in anatomical position.
Teaching Point: Anatomical position standardizes all
directional descriptions.

2. Reference: Ch. 1 — The Body — Forearm rotation and
surface anatomy
Stem: After a distal radius fracture, a patient cannot
comfortably turn the palm upward to hold a bowl. The
, clinician suspects loss of normal forearm rotation. Which
movement is being limited?
Options:
A. Pronation
B. Supination
C. Circumduction
D. Opposition
Correct Answer: B
Rationale — Correct Answer: Supination turns the palm
anteriorly or upward in the standard clinical description
and is essential for activities such as holding a tray. It
depends on coordinated rotation of the radius around the
ulna at the proximal and distal radioulnar joints. Distal
radius injuries often impair this movement.
Rationale — Incorrect Options:
A. Pronation turns the palm posteriorly or downward, the
opposite of the deficit described.
C. Circumduction is a circular movement at ball-and-socket
joints, not a forearm motion.
D. Opposition is primarily a thumb movement at the first
carpometacarpal joint.
Teaching Point: Supination restores the palm to the
anatomical position.

3. Reference: Ch. 1 — The Body — Planes of section and
imaging
, Stem: A neurosurgeon reviewing a midline MRI of the
pituitary wants an image that divides the body into equal
right and left halves. This plane is especially useful for
evaluating midline structures. Which plane is being used?
Options:
A. Coronal plane
B. Transverse plane
C. Midsagittal plane
D. Oblique plane
Correct Answer: C
Rationale — Correct Answer: The midsagittal plane divides
the body into equal right and left halves and is ideal for
assessing midline structures such as the pituitary region,
brainstem, and vertebral alignment. It is a key concept in
both anatomy and imaging interpretation.
Rationale — Incorrect Options:
A. The coronal plane divides the body into anterior and
posterior portions, not right and left halves.
B. The transverse plane divides the body into superior and
inferior parts.
D. The oblique plane cuts at an angle and does not define a
standard anatomical division.
Teaching Point: Midsagittal images are best for symmetric
midline anatomy.
