|Posterior superior alveolar artery|
Plan of branches of maxillary artery
Plan of branches of maxillary artery. (Post. sup. alveolar in lower right.)
|Branches||branches to alveolar canals
branches to gingiva
|Supplies||molar and premolar teeth
lining of the maxillary sinus
|Latin||arteria alveolaris superior posterior|
The posterior superior alveolar artery (posterior dental artery) is given off from the maxillary, frequently in conjunction with the infraorbital artery just as the trunk of the vessel is passing into the pterygopalatine fossa.
Descending upon the tuberosity of the maxilla, it divides into numerous branches, some of which enter the alveolar canals, to supply the molar and premolar teeth and the lining of the maxillary sinus, while others are continued forward on the alveolar process to supply the gingiva.
