The point corresponding with the posterior end of the sphenoparietal suture is named the pterion.


It is situated about 3 cm. behind, and a little above the level of the zygomatic process of the frontal bone.

It marks the junction between four bones:

Clinical significance

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

Clinically, the pterion is relevant because the middle meningeal artery runs beneath it, on the inner side of the skull, which is quite thin at this point.

A blow to the pterion (e.g. in boxing) may rupture the artery causing an extradural haematoma.


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