Origin
The descending palatine artery is a terminal branch of the third part of the maxillary artery as it passes through the pterygopalatine fossa.
Course
The descending palatine artery leaves the pterygopalatine fossa by descending in the greater palatine canal (pterygopalatine, palatomaxillary, or sphenopalatine canal), a canal in the sphenoid and palatine bones.
Branches
The descending palatine artery terminates by giving rise to the greater and lesser palatine arteries before exiting the greater palatine canal.
Supplied Structures
The descending palatine artery supplies the hard and soft palates.
