The pterion is known as the weakest part of the skull.

It is one of the sutures that comprises the pterion.

The anterior division of the middle meningeal artery runs underneath the pterion.

The pterion receives its name from the Greek root pteron, meaning wing.

The pterion is the region where the frontal, parietal, temporal, and sphenoid join together.

The pterion region which overlies the middle meningeal artery is relatively weak and prone to injury.

It is near the pterion.

Consequently, a traumatic blow to the pterion may rupture the middle meningeal artery causing an epidural haematoma.

The pterion is located in the temporal fossa, approximately 2.6 cm behind and 1.3 cm above the posterolateral margin of the frontozygomatic suture.

The species epithet struthiopteris comes from Ancient Greek words, struthio meaning ostrich and pterion meaning wing.

In Greek mythology, Hermes, messenger of the gods, was enabled to fly by winged sandals, and wings on his head, which were attached at the pterion.

Another specific wormian bone, the pterion ossicle, sometimes exists between the sphenoidal angle of the parietal bone and the great wing of the sphenoid bone.

The pterion may also be fractured indirectly by blows to the top or back of the head that place sufficient force on the skull to fracture the pterion.

At the tip of the great wing is a triangular portion, bevelled at the expense of the internal surface, for articulation with the sphenoidal angle of the parietal bone; this region is named the pterion.

Since the pterion is so weak, this type of injury can easily occur and can be secondary due to trauma to other parts of the skull where the impact forces spreads to the pterion.

A particularly weak part of the skull that is vulnerable to damage causing extradural haematoma is the pterion, deep in which lies the middle meningeal artery, which is easily damaged in fractures of the pterion.
