Presents one or more foramina - Zygomatico facial foramina transmitting zygomaticofacial nerves & vessels
Oblique ridge - anterior part gives attachments to zygomaticus minor & posterior part gives attachment to zygomaticus major
along the infraorbital margin near the maxilla give attachment to elevator labii superioris
Temporal surface: has anterior rough part articulating with zygomatic process of maxilla
posterior rough part is smooth forms anterior wall for temporal & infra temporal fossa
