Question

In human beings, cranium is formed by

• A. Eight bones of which two are paired
• B. Ten bones in which two are paired
• C. Twelve bones of which four are paired
• D. Fourteen bones of which six are paired

Answer 1

Answer: (A)

Eight bones of which two are paired

• The skull is composed of two sets of bones cranial (8) and facial (14), that totals to 22 bones.
• The eight cranial bones are 1 ethmoid bone, 1 frontal bone, 1 occipital bone, 2 parietal bones, 1 sphenoid bone, 2 temporal bones.
• Cranial bones protect the brain from damage.
• Parietal and temporal bones are paired cranialbones.
• Hence in human beings, the cranium is formed by eight bones of which two are paired.
• So, the correct answer is 'Eight bones of which two bones are paired'.
