Anatomical terms of neuroanatomy

The (medial and lateral) posterior superior nasal nerves are branches of the maxillary nerve (CN V2) that arise in the pterygopalatine fossa from pterygopalatine ganglion and pass through the sphenopalatine foramen into the nasal cavity to innervate the nasal septum (the medial nerves), and the posterosuperior portion of the lateral wall of the nasal cavity (the lateral nerves).
