A - Sphenoid bone; B - Occipital bone; C - Zygomatic bone; D - Parietal bone; E - Frontal bone; F - Temporal bone
In the above figure,
A - Sphenoid bone: It is an unpaired bone of the neurocranium.
B - Occipital bone: It is the trapezoidal shaped bone found at the lower back area of the cranium.
C - Zygomatic bone: These are the two facial bones that form the cheeks and the lateral walls of the orbits.
D - Parietal bone: These are the two bones in the skull which, when joined together at a fibrous joint, form the sides and roof of the cranium.
E - Frontal bone: It is a bone in human skull. It makes up the bony part of the forehead.
F - Temporal bone: It is found at the sides and base of the skull. It consists of 5 parts.
