Anterior nasal spine

 
Wikipedia: Anterior nasal spine
Bone: Anterior nasal spine
Left maxilla. Nasal surface. (Anterior nasal spine labeled at bottom right.)
The skull from the front. (Anterior nasal spine is not labeled, but is visible at bottom of "nose". Maxilla is yellow bone in center.)
Latin spina nasalis anterior maxillae
Gray's subject #38 158

Medially, the anterior surface of the maxilla is limited by a deep concavity, the nasal notch, the margin of which gives attachment to the Dilatator naris posterior and ends below in a pointed process, which with its fellow of the opposite side forms the anterior nasal spine.
