Ch. 1 — The Body — What is anatomy?
Stem
A clinician palpates a patient’s abdomen and notes a midline
mass that moves with respiration. Using anatomical reasoning
about organ relationships and movements, which organ is most
likely producing this finding? Explain why the movement with
respiration matters when localizing the structure.
Options
A. Sigmoid colon
B. Urinary bladder
C. Liver (left lobe)
D. Pancreas (head)
,Correct answer
C. Liver (left lobe)
Rationales
Correct (3–4 sentences): The liver is attached to the diaphragm
via peritoneal reflections and moves with respiration. A midline
or right-upper quadrant mass that rises and falls with
inspiration is characteristic of a diaphragmatically anchored
organ such as the liver. Gray’s emphasizes positional
relationships between viscera and the diaphragm that explain
respiratory displacement.
A (1–3 sentences): The sigmoid colon is intraperitoneal and
mobile but lies lower in the left lower quadrant and is not
characteristically displaced by diaphragmatic excursions.
B (1–3 sentences): The urinary bladder occupies the pelvis
when empty and rises only when markedly distended; it does
not follow respiratory movements tied to the diaphragm.
D (1–3 sentences): The pancreas is retroperitoneal and lies
deep to the stomach; it does not move appreciably with
diaphragmatic respiration.
Teaching point
Organs attached to the diaphragm move with respiration; liver
follows diaphragmatic excursions.

Ch. 1 — The Body — Imaging
Stem
A junior doctor reviews a chest radiograph where the cardiac
silhouette appears enlarged but the patient is asymptomatic.
Considering imaging principles and anatomy, which anatomical
or technical factor best explains a pseudomediastinal
enlargement on a supine AP chest radiograph?
Options
A. Cardiac hypertrophy only
B. Magnification artifact from increased heart-to-film distance
C. Pericardial effusion producing true enlargement
D. Bilateral pleural effusions compressing the lungs
Correct answer
B. Magnification artifact from increased heart-to-film distance
Rationales
Correct (3–4 sentences): An AP supine chest radiograph
increases the distance between the heart and the image
receptor, causing magnification of the cardiac silhouette. Gray’s
discusses how imaging technique and patient positioning alter
apparent organ size. Thus apparent cardiomegaly on AP films
may be an artifact rather than true enlargement.
A (1–3 sentences): Cardiac hypertrophy causes true
enlargement but would typically correlate with clinical signs and
, remain on correctly positioned radiographs.
C (1–3 sentences): Pericardial effusion enlarges the cardiac
silhouette but is a real pathological finding, not a technical
artifact; clinical correlation and other imaging
(echocardiography) are needed.
D (1–3 sentences): Pleural effusions cause blunting of
costophrenic angles and lung compression, but do not magnify
the heart silhouette as a positioning artifact does.
Teaching point
AP vs PA view and heart-to-film distance significantly affect
apparent cardiac size.

Ch. 1 — The Body — Body systems
Stem
A physiologist asks whether the endocrine or nervous system
would be primarily responsible for a rapid, localized reflex
withdrawal from a hot surface. Using functional system
comparisons, which is correct and why?
Options
A. Endocrine system — because hormones travel in blood to act
quickly at the site
