| Anatomical terms of neuroanatomy | |
The (medial and lateral) posterior superior nasal nerves are branches of the maxillary nerve (CN V2) [3]: 496 that arise in the pterygopalatine fossa from pterygopalatine ganglion [3]: 369–370 and pass through the sphenopalatine foramen into the nasal cavity [3]: 496 to innervate the nasal septum (the medial nerves), and the posterosuperior portion of the lateral wall of the nasal cavity (the lateral nerves).
Median posterior superior nasal nerves
The median posterior superior nasal nerves traverse the roof of the nose to be distributed to the nasal septum. [3]: 370
The largest of the median posterior superior nasal nerves is the nasopalatine nerve (which continues out of the nasal cavity to the hard palate). [3]: 370
Lateral posterior superior nasal nerves
The lateral posterior superior nasal nerves pass anterior-ward in the nasal cavity to be distributed to the posterosuperior portion of the lateral wall of the nasal cavity. [3]: 370
