| greater wing of sphenoid bone | Strong squamous processes extending in a broad superolateral curve from the body of the sphenoid bone. The greater wing presents these suraces (facies): 1) cerebral surface: forms anterior third of the floor of the lateral portions of the middle cranial fossa; 2) temporal surface: forms the deepest portion of the temporal fossa; 3) infratemporal surface, forms the "roof" of the infratemporal fossa; 4) orbital surface: forms posterolateral wall of orbit. The greater wing forms the inferior border of the supraorbital fissure, and is perforated at its root by foramina rotundum ovale, and spinosum and the pterygoid canal. Synonym: ala major ossis sphenoidalis, ala temporalis. (05 Mar 2000) |

| zygomatic border of greater wing of sphenoid bone | The border of the greater wing of the sphenoid that articulates with the zygomatic bone. Synonym: margo zygomaticus alae majoris, zygomatic margin of greater wing of sphenoid bone. (05 Mar 2000) |
| zygomatic margin of greater wing of sphenoid bone | The border of the greater wing of the sphenoid that articulates with the zygomatic bone. Synonym: margo zygomaticus alae majoris, zygomatic margin of greater wing of sphenoid bone. (05 Mar 2000) |
| anterior surface of petrous part of temporal bone | The surface of the petrous part of the temporal bone contributing to the floor of the middle cranial fossa. Synonym: facies anterior partis petrosae ossis temporalis. (05 Mar 2000) |
| articular surface of temporal bone | The smooth portion of the mandibular articular fossa and eminence of the temporal bone that articulates with the disk of the temporomandibular joint. Synonym: facies articularis ossis temporalis. (05 Mar 2000) |
