• D. a - sphenoid bone, b - zygomatic bone, c - occipital bone, d - frontal bone, e - temporal bone, f-parietal bone
• E. a - zygomatic bone, b - occipital bone, c - parietal bone, d - frontal bone, e - sphenoid bone, f - temporal bone

Answer 1

Answer: (C)

a - sphenoid bone, b - occipital bone, c - zygomatic bone, d - parietal bone, e - frontal bone, f - temporal bone

• The sphenoid bone (a) is an unpaired bone of the neurocranium. It is situated in the middle of the skull towards the front, in front of the temporal bone and the basilar part of the occipital bone.
  
• The occipital bone (b) is a cranial dermal bone and the main bone of the occiput (back and lower part of the skull).
  
• The zygomatic bone (C) (cheekbone or malar bone) is a paired bone which articulates with the maxilla, the temporal bone, the sphenoid bone, and the frontal bone.
• One parietal bone (d) is located on each side of the skull just behind the frontal bone.
• The frontal bone (e) is a bowl-shaped bone in the frontal (forehead) region of the skull. It is located superior to the nasal bones and maxillae and anterior to the parietal bones.
• The temporal bones (f) are situated at the sides and base of the skull.
• So, the correct answer is 'a - sphenoid bone, b - occipital bone, c - zygomatic bone, d - parietal bone, e - frontal bone, f - temporal bone'.
