The frontal bone's nasal and orbital part forms the root of the nose.


The frontal bone is one of the 21 bones of the skull joined by immovable joints in the form of sutures.The frontal bone has three parts: squamous part, orbital part and nasal part.

The squamous part forms most of the forehead, orbital part forms roofs of the orbits or eye sockets and nasal cavities and the nasal part i.e the smallest part articulates(forms a joint) with the nasal bone and frontal process of maxilla forming root of the nose.
