Course
The
descending palatine artery branches off of the maxillary artery in the
pterygopalatine fossa and descends through the
greater palatine canal along with the
greater palatine nerve (from the
pterygopalatine ganglion). Once emerging from the
greater palatine foramen, it changes names to the greater palatine artery and begins to supply the
hard palate.
As it terminates it travels through the
incisive canal to
anastomose with the
sphenopalatine artery to supply the
nasal septum
