The cranial suture between the frontal and zygomatic bone is found here. The frontosphenoidal process is thick and serrated. The zygomatic bone itself has four processes, namely the frontosphenoidal, orbital, maxillary and temporal processes. The anterior root, continuous with the lower border, is short but broad and strong it is directed medialward and ends in a rounded eminence, the articular tubercle (eminentia articularis).The posterior root, a prolongation of the upper border, is strongly marked it runs backward above the external auditory meatus.The posterior end is connected to the squama by two roots, the anterior and posterior roots: The anterior end is deeply serrated and articulates with the zygomatic bone. The medial surface is concave, and affords attachment to the masseter. The lateral surface is convex and subcutaneous. The inferior border, short, thick, and arched, has attached to it some fibers of the masseter.

The superior border is long, thin, and sharp, and serves for the attachment of the temporal fascia. This process is at first directed lateralward, its two surfaces looking upward and downward it then appears as if twisted inward upon itself, and runs forward, its surfaces now looking medialward and lateralward. The zygomatic process of the temporal bone is a long, arched process projecting from the lower part of the squamous portion of the temporal bone. Zygomatic process of frontal bone Zygomatic process of frontal bone The zygomatic process is occasionally referred to as the zygoma, but this term usually refers to the zygomatic bone or occasionally the zygomatic arch. The term zygomatic derives from the Greek Ζυγόμα, zygoma, meaning 'yoke'. Zygomatic process of temporal bone from the temporal bone.Zygomatic process of maxilla from the maxilla.Zygomatic process of frontal bone from the frontal bone.The zygomatic processes are three processes (protrusions) from other bones of the skull which each articulate with the zygomatic bone. As a comparison, this is how the skull looks with almost all of the zygomatic process removed. The Zygomatic process forms an 'L' in this picture.
