Greater Palatine Artery
The greater palatine artery is a branch of the descending palatine artery (a terminal branch of the maxillary artery) and contributes to the blood supply of the hard palate and nasal septum. 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 The nasal septum () separates the left and right airways of the nasal cavity, dividing the two nostrils. It is depressed by the depressor septi nasi muscle. Structure The fleshy external end of the nasal septum is called the columella or col .... See also * Greater palatine nerve References E ...

Descending Palatine Artery
The descending palatine artery is a branch of the third part of the maxillary artery supplying the hard and soft palate. Course It descends through the greater palatine canal with the greater and lesser palatine branches of the pterygopalatine ganglion, and, emerging from the greater palatine foramen, runs forward in a groove on the medial side of the alveolar border of the hard palate to the incisive canal; the terminal branch of the artery passes upward through this canal to anastomosis, anastomose with the sphenopalatine artery. Branches Branches are distributed to the gums, the palatine glands, and the mucous membrane of the roof of the mouth; while in the Greater palatine canal, pterygopalatine canal it gives off twigs which de
