Posterior superior alveolar artery

from Wikipedia, the free encyclopedia

The arteria alveolaris superior posterior ("upper posterior dental artery ") is an artery of the head in humans.

The posterior superior alveolar artery arises from the third section of the maxillary artery in the pterygopalatine fossa (wing and palate fossa ), often together with the infraorbital artery . It divides into numerous branches that pull into the tooth sockets of the upper posterior teeth ( molars and premolars ) and supply these teeth. Branches also supply the gums and the mucous membrane of the maxillary sinus in this region.
