Question

A skull bone is

• A. Atlas
• B. Pterygoid
• C. Arytenoid
• D. Coracoid

Answer 1

The correct option is

B

Pterygoid

• The skull is composed of two sets of bones. They are cranial (8) and facial (14), that totals to 22 bones.

• The bones of the cranium include the frontal (1), parietal (2), occipital (1), temporal (2), sphenoid (1), and ethmoid bones (1).

• The pterygoid is a paired bone which forms a part of the palate in many vertebrates, behind the palatine bones. In humans, it becomes the pterygoid processes of the sphenoid bone. Hence pterygoid is a skull bone.

So, the correct answer is 'Pterygoid'.
