Sections:
The asterion is the junction on the side of the posteroinferior calvarium where three sutures meet:
It represents the site of the closed mastoid fontanelle. It is located at the posterior end of the parietotemporal suture, whereas the pterion is located at the anterior end.
It is one of the skull landmarks, craniometric points for radiological or anthropological skull measurement.
Osseous defects of the asterion are associated with neurofibromatosis type 1.
