Inferiorly this suture is con- tinued obliquely downwards between the occipital bone and the posterior border of the mastoid portion of the temporal, where it forms the sutura occipitomastoidea.

Fig. 169.—Norma Lateralis of the Skull. The occipital, sphenoid, ethmoid, and lacrimal bones and the mandible are coloured blue. The parietal, zygomatic, and nasal bones are coloured red.

These three sutures just described meet in triradiate fashion at a point called the asterion. Anteriorly the curve of the squamous suture is continued downward between the anterior edge of the squamous part of the temporal and the posterior border of the great wing of the sphenoid; inferiorly it lies in plane with the middle of the zygomatic Please note that these images are extracted from scanned pag
