Anterosuperior quadrant, by the anterior ethmoidal artery, a branch of ophthalmic artery. 2. Anteroinferior quadrant, by branches the greater palatine artery and by the alar branch of the lateral nasal artery (which in turn is a branch of the facial artery). 3. Posterosuperior quadrant, by sphenopalatine artery, a branch of maxillary artery and by the posterior etmoidal artery. 4. Posteroinferior quadrant, by branches of greater palatine artery, which pierces the perpendicular plate of palatine. The medial wall or the nasal septum is supplied by the following arteries: 1. Septal branch of the anterior ethmoidal artery. 2. Septal branch of the posterior ethmoidal artery. This artery is smaller than the anterior one. 3.Posterior Septal branch of the sphenopalatine artery. 4. Septal branch of the terminal part of greater palatine artery. 5. Septal branch of the superior labial artery (a branch of facial artery). In the anteroinferior part of the nasal septum is a very important vascular network called Little’s area or the Kiesselbach’s plexus. Four arteries are participating in this anastomosis: anterior etmoidal, sphenopalatine, greater palatine and the septal branch of the superior labial artery. #nasalcavity #nosebloodsupply #maxilla
