The middle meningeal artery is the largest of the three (paired) arteries that supply the meninges, the others being the anterior meningeal artery and the posterior meningeal artery. The anterior branch of the middle meningeal artery runs beneath the pterion. It is vulnerable to injury at this point, where the skull is thin. Rupture of the ...
The foramen spinosum is a small open hole in the greater wing of the sphenoid bone that gives passage to the middle meningeal artery and vein, and the meningeal branch of the mandibular nerve (sometimes it passes through the foramen ovale instead).
The internal surface [Fig. 2] is concave; it presents depressions corresponding to the cerebral convolutions, and numerous furrows (grooves) for the ramifications of the middle meningeal artery; the latter run upward and backward from the sphenoidal angle, and from the central and posterior part of the squamous border.

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 that ascends through the foramen ovale to enter the cranial cavity and supply the dura mater of the floor of the middle cranial fossa and of the trigeminal cave, and to the trigeminal ganglion (representing the main ...
The petrosal branch of middle meningeal artery enters the hiatus for greater petrosal nerve, supplies the facial nerve and anastomoses with the stylomastoid branch of the posterior auricular artery. See also
