What division of the Maxillary artery are the branches found in the Pterygopalatine Fossa?
3rd Division of Maxillary Artery
The Descending Palatine artery has two branches. What are they?
Lesser Palatine and Greater Palatine arteries
What space has branching of the Descending Palatine artery?
Palatine Canal is where the Lesser and Greater Palatine arteries branch off of the Descending Palatine artery
What is the name of the artery that runs posterior in the Pterygoid canal?
Artery of Pterygoid Canal
