Nasal bone

The nasal bone (Latin nasal bone ) is a paired bone of the facial skeleton. It forms the largest part of the nasal roof and thus the upper wall of the nasal cavity.

On the inside of the nasal bone, the nasal septum are (septum nasi) and the upper nasal turbinates ( nasal concha superior) attached. The latter limits the upper nasal passage ( "smelling passage ").

In many mammals (except humans, predators ) the nasal bone protrudes forward beyond the premaxillary bone ( premaxilla ), so that an open forward, acute-angled cut ( notch nasoincisiva ) is formed.

Punches from the outside, it can easily lead to a fracture of the nasal bone (see Nasal fracture ).
