Theaccessory meningeal artery (alsoaccessory branch of middle meningeal artery,pterygomeningeal artery,small meningeal orparvidural branch) is a branch of themaxillary artery that ascends through theforamen ovale to enter thecranial cavity and supply thedura mater of the floor of themiddle cranial fossa and of thetrigeminal cave, and to thetrigeminal ganglion (representing the main source of artierial blood for this ganglion).[1]
The artery sometimes instead arises from themiddle meningeal artery.[citation needed]
Only about 10% of the blood flowing through this artery reaches intracranial structures.[2] The remaining blood flow is dispersed to extracranial structures around the infratemporal fossa.[citation needed]
Reflecting this fact,Terminologia Anatomica lists entries for both "accessory branch of middle meningeal artery" and "pterygomeningeal artery".[3]
