Where is the middle meningeal artery located?
Where is the middle meningeal artery located?
maxillary artery
The middle meningeal artery (Latin: arteria meningea media) is typically the third branch of the first portion of the maxillary artery. After branching off the maxillary artery in the infratemporal fossa, it runs through the foramen spinosum to supply the dura mater (the outer meningeal layer) and the calvaria.
What part of the brain does the middle meningeal artery supply?
The middle meningeal artery most often branches off the maxillary artery and courses into the middle cranial fossa via the foramen spinosum. The middle meningeal artery provides blood to the dura mater through and through its branching arteries also supplies the periosteum of the inner aspects of the cranial bones.
What artery is most likely to be injured should there be repeated blows to the Pterion?
Head injury This typically occurs when the middle meningeal artery is torn by a skull fracture in the region of the pterion, where the bone is thin and is closely related to the underlying vessel (Fig. 9.4).
Is the middle meningeal artery extracranial?
The first extracranial segment of the MMA is from its origin to its entry into the foramen spinosum. The more anterior the origin of the MMA is, the more oblique backward is the extracranial segment. At the level of the foramen spinosum, the artery bends anteriorly and laterally to follow the temporal fossa.
What is the accessory meningeal artery?
The accessory meningeal artery is a branch of the maxillary artery but can also branch from the middle meningeal artery. The artery passes upwards through the foramen ovale to supply the trigeminal ganglion and the dura mater of Meckel cave and the middle cranial fossa.
What is middle meningeal artery embolization?
Middle meningeal artery embolization is a minimally invasive angiography procedure completed with use of fluoroscopy. Access is obtained through the femoral or radial artery and a catheter is advanced to the MMA.
Where is the skull the thinnest?
Pterion
- The frontal, parietal, temporal and sphenoid bones unite at the ‘pterion’ – the thinnest part of the skull.
- The middle meningeal artery runs in a groove on the inner table of the skull in this area.
Where does middle meningeal vein drain?
DSA revealed a high flow dural arteriovenous fistula of the right middle meningeal artery branches with drainage into the sphenoidal and parietal portions of the anterior branch of the middle meningeal veins, the posterior and petrosal branches of the middle meningeal veins and retrograde drainage into the cavernous …
Where does the posterior meningeal artery originate?
The posterior meningeal artery originates from the posterosuperior surface of the superior medial loop and supplies the posterior fossa dura, posterior tentorium, and the squamous portion of the temporal bone.
What lies behind the pterion?
The pterion is the region where the frontal, parietal, temporal, and sphenoid bones join together. It is located on the side of the skull, just behind the temple….

Where is skull the thickest?
Conclusion: The thickest area of the skull is the parasagittal posterior parietal area in male skulls and the posterior parietal area midway between the sagittal and superior temporal line in female skulls.
