Palatine nerve major

from Wikipedia, the free encyclopedia
Branches of the pterygopalatine ganglion

The palatine nerve (Latin for "large palatine nerve") is a nerve branch from the pterygopalatine ganglion . It runs through the large palatal canal ( canalis palatinus major ) between the palatine bone and the upper jaw and enters the hard palate at the large palatal opening ( foramen palatinum majus ) to branch out there.

The greater palatine nerve supplies the posterior (dorsal) two thirds of the hard palate and the gums of the maxillary posterior teeth in a sensitive manner. At the rear edge of the inferior turbinate , it gives off the rami nasales posteriores inferiores and other fine branches for supplying the inferior turbinate, nasopharynx , choane and the nasal surface of the soft palate .

In dentistry, the nerve can be numbed by conduction anesthesia to switch off pain in the posterior region.
