Origin: Greater palatine nerve.
Course: Pass through minute foramina in the palatine canal to enter the posterior nasal cavity where they distribute fibers to the mucosa of the posterior lateral nasal wall.
Branches: None.
Supply: Sensory: convey general sensation from the mucosa of the posterior lateral wall of the nasal cavity; Parasympathetic: innervation to mucosal glands of the same territories.

Origin
The inferior posterior nasal branches of the greater palatine nerve originate from the greater palatine nerve, as it passes through the greater palatine canal.
Course
From their origin, the inferior posterior nasal branches run anteriorly through small foramina through the perpendicular plate of the palatine bone, to exit the greater palatine canal and enter the posterior part of the nasal cavity. From there, fibers are distributed to the mucosa of the posterior lateral nasal wall.
Branches
There are no named branches.
Supplied Structures
The inferior posterior lateral nasal branches of the greater palatine nerve are mixed nerves carrying sensory and parasympathetic fibers. The sensory fibers have cell bodies located in the trigeminal ganglion while the parasympathetic fibers originate in the pterygopalatine ganglion.
The sensory fibers convey general sense information from the mucosa of the posterior and inferior lateral nasal wall.
The parasympathetic fibers innervate the small mucosal glands of the same territories.

Greater Palatine Nerve
The greater palatine nerve travels with the greater palatine artery through the pterygopalatine canal to its respective foramen in the hard palate, and the nasopalatine branch of the posterior superior nasal branch of the maxillary nerve, which emerges from the incisive canal, innervates the palate and associated alveolus of the maxilla.
