In this form it is known as a blind arcade or an arcature, and is also called wall-arcade.

5. n. In anatomy and zoology, those portions of the cranium having an arch-like structure and running from the postero-external to the orbital region. The inferior temporal arcade corresponds to the zygoma of mammals and is largely or entirely formed by the squamosal and jugal. The superior arcade, lacking in most vertebrates, is formed by the postorbital. A. S. Woodward, Vertebrate Palæontol., p. 144. See cuts under Diapsida and Synapsida.
