Section 1: Anatomy (Questions 1-30)
1. Which of the following bones is not part of the axial skeleton?
A) Sternum
B) Coccyx
C) Scapula
D) Sphenoid
Correct Answer: C
Rationale: The axial skeleton consists of the skull, vertebral column (including
coccyx), and thoracic cage (including sternum). The scapula is part of the
appendicular skeleton (pectoral girdle).
2. The foramen magnum is located in which bone?
A) Frontal
B) Temporal
C) Sphenoid
D) Occipital
Correct Answer: D
,Rationale: The foramen magnum is a large opening in the occipital bone
through which the spinal cord connects to the brain.
3. Which cranial nerve is responsible for the sensation of smell?
A) Optic (CN II)
B) Olfactory (CN I)
C) Trigeminal (CN V)
D) Facial (CN VII)
Correct Answer: B
Rationale: The olfactory nerve (CN I) is a sensory nerve responsible for
transmitting the sense of smell from the nasal cavity to the brain.
4. The biceps brachii muscle inserts on which bony landmark?
A) Coracoid process
B) Radial tuberosity
C) Olecranon process
D) Greater tubercle of humerus
Correct Answer: B
Rationale: The biceps brachii inserts on the radial tuberosity of the radius,
allowing it to flex the elbow and supinate the forearm.
5. The pulmonary valve is located between which two structures?
A) Right atrium and right ventricle
B) Left ventricle and aorta
C) Right ventricle and pulmonary trunk
D) Left atrium and left ventricle
,Correct Answer: C
Rationale: The pulmonary valve (or pulmonic valve) guards the opening from
the right ventricle into the pulmonary trunk, which carries deoxygenated
blood to the lungs.
6. Which structure is not a component of the portal triad in the liver?
A) Hepatic artery
B) Portal vein
C) Bile duct
D) Central vein
Correct Answer: D
Rationale: The portal triad consists of a branch of the hepatic artery, a branch
of the portal vein, and a bile duct. The central vein is located in the center of
the lobule.
7. The pituitary gland is located in which cranial fossa?
A) Anterior cranial fossa
B) Middle cranial fossa
C) Posterior cranial fossa
D) Pterygopalatine fossa
Correct Answer: B
Rationale: The pituitary gland (hypophysis) sits within the sella turcica of the
sphenoid bone, which is in the middle cranial fossa.
8. Which of the following structures is found in the medulla oblongata?
A) Arcuate nucleus
B) Red nucleus
, C) Substantia nigra
D) Mammillary bodies
Correct Answer: A
Rationale: The arcuate nucleus is a nucleus in the medulla oblongata involved
in respiration. The red nucleus and substantia nigra are in the midbrain, and
mammillary bodies are in the hypothalamus.
9. The femoral artery is a direct continuation of which artery?
A) Popliteal artery
B) Deep femoral artery
C) External iliac artery
D) Internal iliac artery
Correct Answer: C
Rationale: The external iliac artery continues past the inguinal ligament and
becomes the femoral artery, the main artery of the thigh.
10. Which structure separates the right and left ventricles of the heart?
A) Interatrial septum
B) Interventricular septum
C) Coronary sulcus
D) Anterior interventricular sulcus
Correct Answer: B
Rationale: The interventricular septum is the thick muscular wall that
separates the two lower chambers (ventricles) of the heart.
11. The glenoid cavity is a part of which bone?
