Zygomatico- orbital foramen Zygomatico facial canal —~~ For articulation with maxilla Orbital process Temporal process Infra- temporal surface Fig. 162.—The Right Zygomatic Bone. A, Lateral Side ; B, Medial Side. (processus frontosphenoidalis), the marginal or pointed extremity of the maxillary border, and the temporal (processus temporalis). The most elevated part of the convex malar surface (facies malaris) forms the malar tuberosity. The temporal process ends posteriorly in an oblique edge, which articulates with the extremity of the zygomatic process of the temporal bone. The fronto- sphenoidal process, the most prominent of the three, is united superiorly to the zygomatic process of the frontal bone. The edge between the frontal and temporal processes is thin and sharp; it affords attachment to the temporal fascia, and near its upper end there is usually a pronounced angle (processus marginalis), formed by a sudden change in the direction of the border of the bone. It is just below this point that the zygomatico-temporal branch of the zygomatic nerve becomes cutaneous. The inferior margin of the temporal process is somewhat thicker and rounded; it extends downwards and forwards towards the inferior angle, where the bone articulates with the maxilla, and is there confluent with the ridge which separates the facial from the infra-temporal aspect of the maxilla. This edge of the bone is sometimes called the masseteric border, since it affords attachment to the fibres of origin of the masseter muscle. Sweeping downwards, in front of the fronto-sphenoidal process, is a curved edge which terminates inferiorly in a pointed process. This border forms the lateral and, in part, the inferior margin of the orbital cavity. Between the anterior extremity of the masseteric edge and the pointed anterior angle there is an irregular suture by which the bone is joined to the maxilla. The opening
