The anterior nasal spine, or anterior nasal spine of maxilla, is a bony projection in the skull that serves as a cephalometric landmark. [1] The anterior nasal spine is the projection formed by the fusion of the two maxillary bones at the intermaxillary suture.
The piriform aperture, pyriform aperture, or anterior nasal aperture is a pear-shaped opening in the human skull. Its long axis is vertical, and narrow end upward; in the recent state it is much contracted by the lateral nasal cartilage and the greater and lesser alar cartilages of the nose .
The two horizontal plates join at the midline and form the posterior nasal spine that gives attachment to the musculus uvulae in the uvula. The two maxilla bones join at the base of the nose at the lower nasal midline between the nostrils, and at the top of the philtrum to form the anterior nasal spine. This thin projection of bone holds the ...
The body of the maxilla: pyramid-shaped; has an orbital, a nasal, an infratemporal, and a facial surface; contains the maxillary sinus. Four processes: the zygomatic process; the frontal process; the alveolar process; the palatine process; It has three surfaces: [5] the anterior, posterior, medial; Features of the maxilla include: [5]

Its medial surface forms part of the lateral wall of the nasal cavity; at its upper part is a rough, uneven area, which articulates with the ethmoid, closing in the anterior ethmoidal cells; below this is an oblique ridge, the ethmoidal crest, the posterior end of which articulates with the middle nasal concha, while the anterior part is termed ...
The nasal spine (spina nasalis) may refer to: Anterior nasal spine (spina nasalis anterior maxillae) Posterior nasal spine (spina nasalis posterior ossis palatini)
In human anatomy, the premaxilla is referred to as the incisive bone (os incisivum) and is the part of the maxilla which bears the incisor teeth, and encompasses the anterior nasal spine and alar region. In the nasal cavity, the premaxillary element projects higher than the maxillary element behind. The palatal portion of the premaxilla is a ...
