The accessory meningeal artery (also accessory branch of middle meningeal artery, pterygomeningeal artery, small meningeal or parvidural branch) is a branch of the maxillary artery, sometimes derived from the middle meningeal artery.

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. [cite journal | author = Vitek J | title = Accessory meningeal artery: an anatomic misnomer. | journal = AJNR Am J Neuroradiol | volume = 10 | issue = 3 | pages = 569–73 | year =1989 | pmid = 2501989]

Reflecting this fact, Terminologia Anatomica lists entries for both "accessory branch of middle meningeal artery" and "pterygomeningeal artery".cite book |author=Federative Committee on Anatomical Termi |title=Terminologia Anatomica: International Anatomical Terminology |publisher=Thieme Stuttgart |location= |year=1998 |pages= |isbn=3-13-114361-4 |oclc= |doi=]
