Nasal bone
The nasal bone ( Latin os nasale ) is a pair of bones of the facial skull . It forms most of the roof of the nose and thus the upper wall of the nasal cavity .
The nasal septum ( septum nasi ) and the upper turbinate ( concha nasi superior ) are attached to the inside of the nasal bone . The latter also limits the upper nasal passage ("olfactory duct").
In many mammals (exceptions: humans, predators ) the nasal bone protrudes forward beyond the intermaxillary bone ( os incisivum ), so that an acute-angled incision ( incisura nasoincisiva ) is formed.
External blows can easily fracture the nasal bone (see nasal bone fracture ).
