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.
It enters the skull through the
foramen ovale, and supplies the semilunar ganglion and dura mater.
Nomenclature [ edit ]
Only about 10% of the blood flowing through this artery reaches intracranial structures.
The remaining blood flow is dispersed to extracranial structures around the infratemporal fossa. [1 ]
Reflecting this fact,
Terminologia Anatomica lists entries for both "accessory branch of middle meningeal artery" and "pterygomeningeal artery". [2 ]
