Question #351
Considering the pterion, which of the following statements is true?
The pterion is the junction where four bones meet: the greater wing of the sphenoid, the squamous temporal bone, the frontal and parietal bones.
Anatomically it also marks the point where the anterior division of the middle meningeal artery runs. A direct blow here may result in fracture, damage to this artery and subsequent formation of an extradural haematoma.
The pterion is located two fingers’ breadth above the zygomatic arch and a thumb’s breadth posterior to the frontal process of the zygomatic bone.
