| facies glutea ossis ilii | The external surface of the wing of the ilium marked by the anterior, posterior and inferior gluteal lines that separate the origins of the gluteal muscles. Synonym: facies glutea ossis ilii. (05 Mar 2000) |
|---|---|
| facies inferior partis petrosae ossis temporalis | Inferior surface of petrous part of the temporal bone; the portion of the petrous part of the temporal bone that contributes to the external base of the skull. Synonym: facies inferior partis petrosae ossis temporalis. (05 Mar 2000) |
| facies interna ossis frontalis | The surface of the frontal bone that contributes to the wall of the cranial cavity. Synonym: facies interna ossis frontalis. (05 Mar 2000) |
| facies interna ossis parietalis | The concave surface of the parietal bone forming part of the wall of the cranial cavity. Synonym: facies interna ossis parietalis. (05 Mar 2000) |
| facies lateralis ossis zygomatici | The lateral surface of the zygomatic bone. Synonym: facies lateralis ossis zygomatici. (05 Mar 2000) |
| facies maxillaris ossis palatini | The part of the anterior surface of the greater wing of the sphenoid bone that is perforated by the foramen rotundum and forms the posterior boundary of the pterygopalatine fossa. (05 Mar 2000) |
| facies nasalis ossis palatini | The nasal surface of the perpendicular lamina of the palatine bone that forms part of the lateral wall of the nasal cavity, the nasal surface of the horizontal lamina of the palatine bone that forms part of the floor of the nasal cavity. Synonym: facies nasalis ossis palatini. (05 Mar 2000) |
| facies palatina laminae horizontalis ossis palatini | The inferior surface of the horizontal plate of the palatine bone. Synonym: facies palatina laminae horizontalis ossis palatini. (05 Mar 2000) |
| facies posterior partis petrosae ossis temporalis | The surface of the petrous part of the temporal bone that contributes to the posterior cranial fossa. Synonym: facies posterior partis petrosae ossis temporalis. (05 Mar 2000) |
| facies sacropelvina ossis ilii | The medial surface of the ilium behind and below the iliac fossa; it includes the iliac tuberosity, the auricular surface and the smooth pelvic surface below and in front of the auricular surface. Synonym: facies sacropelvina ossis ilii. (05 Mar 2000) |
| lineae transversa ossi sacri | One of four ridges that cross the pelvic surface of the sacrum; these mark the positions of the intervertebral disks between the bodies of the five sacral vertebrae in the immature bone. Synonym: lineae transversa ossi sacri. (05 Mar 2000) |
| ala major ossis sphenoidalis | 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) |
| ala minor ossis sphenoidalis | One of a bilateral pair of triangular, pointed plates extending laterally from the anterolateral body of the sphenoid bone. Forming the posteriormost portion of the floor of the anterior cranial fossa, their sharp posterior edge forms the sphenoidal ridge separating anterior and middle cranial fossae. The medial end of the lesser wing attaches to the body by means of two pedicles, thus forming the optic canal. The wing itself forms the superior margin of the supraorbital fissure. Synonym: ala minor ossis sphenoidalis, ala orbitalis, Ingrassia's apophysis, Ingrassia's wing. (05 Mar 2000) |
| ala ossis ilii | The upper flaring portion of the ilium. Synonym: ala ossis ilii. (05 Mar 2000) |
| angulus frontalis ossis parietalis | The anterior superior angle of the parietal bone. Synonym: angulus frontalis ossis parietalis. (05 Mar 2000) |
