occipitomastoid suture A suture between the occipital bone and the mastoid portion of the temporal bone. The occipitomastoid and lambdoid sutures meet at the asterion. Synonym: The occipitomastoid and lambdoid sutures meet at the asterion.

The squamosal suture, or squamous suture, arches backward from the pterion and connects the temporal squama with the lower border of the parietal bone: this suture is continuous behind with the short, nearly horizontal parietomastoid suture, which unites the mastoid process of the temporal with the region of the mastoid angle of the parietal bone.
