The nasopalatine nerve originates at the sphenopalatine foramen and runs obliquely along the septum in an anterior-inferior direction and traverses the incisive foramen to reach the anterior palate.

  Figure 3. The greater palatine nerve emanates at the greater palatine foramen and runs anteriorly along the hard palate, where it joins with the nasopalatine nerve to contribute to sensation of the anterior palate.
