Course
It enters the skull through the foramen ovale, and supplies the semilunar ganglion and dura mater.
Nomenclature
Only about 10% of the blood flowing through this artery reaches intracranial structures. [1]
Reflecting this fact, Terminologia Anatomica lists entries for both "accessory branch of middle meningeal artery" and "pterygomeningeal artery".[2]
