    • n pterion In craniometry, the region where the frontal, squamosal, parietal, and sphenoid bones meet or approach one another. The squamosal is usually cut off from the frontal by a short line of sphenoparietal articulation, where the lower anterior corner of the parietal joins the tip of the alisphenoid; but in some cases this line is reduced to nothing, and then the frontal and squamosal come into contact. See cut under craniometry.
