Q

The Descending Palatine artery has two branches. What are they?

A

Lesser Palatine and Greater Palatine arteries

6
Q

What space has branching of the Descending Palatine artery?

A

Palatine Canal is where the Lesser and Greater Palatine arteries branch off of the Descending Palatine artery

7
Q
