1. Which nerve innervates the deltoid muscle?
A. Radial nerve
B. Musculocutaneous nerve
C. Ulnar nerve
D. Axillary nerve
Rationale: The axillary nerve supplies the deltoid and teres
minor muscles and provides sensation over the lateral shoulder.
2. The surgical neck of the humerus is most closely associated
with injury to which structure?
A. Radial nerve
B. Median nerve
C. Axillary nerve
D. Musculocutaneous nerve
Rationale: The axillary nerve winds around the surgical neck of
the humerus and is vulnerable in fractures.
3. Which artery supplies the majority of blood to the
myocardium?
A. Pulmonary artery
, B. Aorta
C. Coronary arteries
D. Internal carotid arteries
Rationale: The coronary arteries arise from the ascending aorta
and supply the heart muscle.
4. The femoral triangle contains all of the following EXCEPT:
A. Femoral artery
B. Femoral vein
C. Femoral canal
D. Femoral nerve
Rationale: The femoral nerve lies outside the femoral sheath,
unlike the artery and vein.
5. Which vertebral level corresponds to the inferior angle of the
scapula?
A. T5
B. T7
C. T9
D. L1
Rationale: The inferior angle of the scapula aligns with the T7
vertebra.
6. Damage to the radial nerve at the spiral groove would most
likely cause:
A. Claw hand
B. Ape hand
C. Wrist drop
D. Loss of thumb opposition
Rationale: Radial nerve injury affects wrist extensors, resulting
in wrist drop.
, 7. The primary function of the rotator cuff is to:
A. Abduct the arm
B. Flex the shoulder
C. Rotate the forearm
D. Stabilize the glenohumeral joint
Rationale: The rotator cuff stabilizes the head of the humerus
within the glenoid cavity.
8. Which muscle is responsible for knee extension?
A. Hamstrings
B. Gastrocnemius
C. Sartorius
D. Quadriceps femoris
Rationale: The quadriceps femoris is the main extensor of the
knee.
9. The anatomical snuffbox contains which artery?
A. Ulnar artery
B. Brachial artery
C. Radial artery
D. Axillary artery
Rationale: The radial artery passes through the anatomical
snuffbox.
10. Which cranial nerve controls the lateral rectus muscle?
A. Oculomotor (III)
B. Trochlear (IV)
C. Optic (II)
D. Abducens (VI)
Rationale: The abducens nerve innervates the lateral rectus
muscle.
