Superciliary arch
Arcus superciliaris
Definition
The superciliary arches, also known as supraorbital ridges, are raised bony areas found above the superior margin of each eye socket. These arched elevations are prominent medially and are connected together by a smooth raised area known as the glabella. They divide the forehead area, i.e. the squamous part of frontal bone, from the roof of the eye sockets, i.e. the orbital part of frontal bone. Above the superciliary arches, there is a shallow groove separating them from the frontal eminences on both the right and left sides.
