Vomer

Frontal
These bones form the sides and lower part of the cranium; they are positioned below the cranium
Temporal
This bone forms the back of the cranium. It has a large opening called the foramen Magnus through which part of the spinal cord passes through, It articulates with the vertebrae at the condyles of the skull
Occipital
These form the top and sides of the cranium
Parietal
This bone is positioned below the frontal bone and in front of the sphenoid bone. It helps to form the orbital cavity and the nasal cavity
Ethmoid
Very small bones positioned behind and lateral to the nasal bones. They are in the eye socks and contain foramina for the passage of the tear duct (nasolacrimal duct) hence the name
