Orbital Bones
Jump To
The orbital socket orbit comes the fusion of orbital bones, namely the frontal bone, sphenoid bone, zygomatic bone, the Palatine bones, the maxillary bone, and the lacrimal bone. Blood vessels and nerves within the orbital socket are supplied through fissures. The three main conduits are the superior orbital fissure, the inferior orbital fissure, and the optic canal. While the superior orbital fissure allows for the passage of the frontal nerve, lacrimal nerve, nasociliary nerve, the inferior orbital fissure allows for the passage of the infraorbital nerve, zygomatic nerve, infraorbital artery and vein, and parasympathetic nerve supplying the lacrimal gland.
