Quick Facts

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.
