Origin
The frontal branch of the middle meningeal artery is one of two arteries that arise from the middle meningeal artery after it passes through the foramen spinosum to enter the cranial cavity. The frontal branch is much larger than the parietal branch of the middle meningeal artery.
Course
The frontal branch of the middle meningeal artery crosses over the greater wing of the sphenoid bone and enters the sphenoparietal canal, a groove in the sphenoid angle of the parietal bone. The frontal branch divides into numerous rami that extend between the dura mater and the cranium, with some rami extending as far as the vertex.
Branches
There are no named branches; however, it does anastomose with its fellow branch of the opposite side.
Supplied Structures
The frontal branch of the middle meningeal artery supplies the anterior portion of dura mater and cranium.

Artery
When the artery is occluded blood is forced through the collateral vessels, drastically increasing fluid shear stress and triggering an inflammatory response which drives vessel remodeling.
