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 artery may give rise to an epidural hematoma. In the dry cranium, the middle meningeal, which runs within the dura mater surrounding the brain, makes a deep groove in the calvarium.
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).
Lateral to the foramen ovale is the foramen spinosum, for the passage of the middle meningeal vessels, and a recurrent branch from the mandibular nerve. Medial to the foramen ovale is the foramen lacerum ; in the fresh state the lower part of this aperture is filled up by a layer of fibrocartilage , while its upper and inner parts transmit the ...
superiorly, by the greater wing of the sphenoid below the infratemporal crest, and by the under surface of the temporal squama, containing the foramen ovale, which transmits the mandibular branch of the trigeminal nerve, and the foramen spinosum, which transmits the middle meningeal artery.
The foramen spinosum, in the posterior angle near to and in front of the spine; it is a short canal that transmits the middle meningeal vessels and a recurrent branch from the mandibular nerve. The foramen petrosum, a small occasional opening, between the foramen spinosum and foramen ovale, for transmission of the lesser petrosal nerve.
The middle meningeal nerve (meningeal or dural branch) is given off from the maxillary nerve (CN V 2) directly after its origin from the trigeminal ganglion, before CN V 2 enters the foramen rotundum. It accompanies the middle meningeal artery and vein once the artery and vein enter the cranium through the foramen spinosum and supplies the dura ...
Meningeal artery may refer to Anterior meningeal branch of anterior ethmoidal artery; Meningeal branches of vertebral artery; Middle meningeal artery;
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
