Question 1:
Osteomalacia in adults is caused by a deficiency of:
A. Vitamin A
B. Vitamin C
C. Vitamin D
D. Vitamin K
Answer: C. Vitamin D
Rationale: Osteomalacia is the adult equivalent of rickets, caused by vitamin D deficiency
leading to defective bone mineralization. Bones become soft and prone to fracture.
Question 2:
Paget's disease of bone is characterized by:
A. Excessive bone resorption followed by disorganized bone formation
B. Decreased bone resorption
C. Normal bone remodeling
D. Increased bone density without structural changes
Answer: A. Excessive bone resorption followed by disorganized bone formation
Rationale: Paget's disease involves increased osteoclast activity followed by excessive,
disorganized bone deposition, resulting in weak, enlarged bones.
,Question 3:
Achondroplasia is a condition caused by:
A. Excessive growth hormone
B. Defective endochondral ossification
C. Vitamin D deficiency
D. Calcium deficiency
Answer: B. Defective endochondral ossification
Rationale: Achondroplasia is a genetic disorder that impairs endochondral ossification,
particularly in long bones, resulting in short stature (dwarfism).
Question 4:
Which foramen is located in the sphenoid bone and allows passage of the optic nerve?
A. Foramen ovale
B. Optic canal
C. Foramen rotundum
D. Jugular foramen
Answer: B. Optic canal
Rationale: The optic canal is located in the sphenoid bone and transmits the optic nerve
(CN II) and ophthalmic artery.
Question 5:
Which foramen is located in the temporal bone and allows passage of the internal
jugular vein?
A. Foramen ovale
B. Jugular foramen
C. Foramen rotundum
D. Carotid canal
Answer: B. Jugular foramen
Rationale: The jugular foramen is located between the temporal and occipital bones and
transmits the internal jugular vein and glossopharyngeal, vagus, and accessory nerves.
,Question 6:
Which foramen is located in the occipital bone and allows passage of the spinal cord?
A. Foramen ovale
B. Foramen magnum
C. Jugular foramen
D. Carotid canal
Answer: B. Foramen magnum
Rationale: The foramen magnum is the large opening in the occipital bone through which
the spinal cord passes to connect with the brainstem.
Question 7:
The styloid process is a feature of which bone?
A. Frontal bone
B. Temporal bone
C. Occipital bone
D. Sphenoid bone
Answer: B. Temporal bone
Rationale: The styloid process is a sharp projection on the temporal bone that serves as an
attachment point for muscles and ligaments of the tongue and neck.
Question 8:
Which bone forms the prominence of the chin?
A. Maxilla
B. Mandible
C. Zygomatic
D. Nasal
Answer: B. Mandible
Rationale: The mandible forms the lower jaw and the prominence of the chin (mental
protuberance).
, Question 9:
The lacrimal bone is located:
A. In the nasal cavity
B. In the medial wall of the orbit
C. In the lateral wall of the orbit
D. In the roof of the mouth
Answer: B. In the medial wall of the orbit
Rationale: The lacrimal bone is a small bone in the medial wall of the orbit that contains
the lacrimal fossa for the tear sac.
Question 10:
The vomer bone forms:
A. The roof of the mouth
B. The lower part of the nasal septum
C. The upper jaw
D. The cheekbone
Answer: B. The lower part of the nasal septum
Rationale: The vomer is a thin, flat bone that forms the lower part of the nasal septum.
Question 11:
Which skull bone is the only one that does not articulate with any other bone?
A. Mandible
B. Hyoid
C. Vomer
D. Palatine
Answer: B. Hyoid
Rationale: The hyoid bone is a U-shaped bone in the neck that does not articulate with
any other bone. It serves as an attachment point for tongue and neck muscles.
