| pars nasalis ossis frontalis | Nasal portion of the frontal bone which lies between the two orbital parts anteriorly and forms part of the roof of the nasal cavity. Synonym: pars nasalis ossis frontalis. (05 Mar 2000) |
|---|---|
| pars orbitalis ossis frontalis | The portion of the frontal bone that contributes to the formation of the orbits; the most rostral of three cortical convolutions that togetther form the inferior frontal gyrus. Synonym: pars orbitalis ossis frontalis. (05 Mar 2000) |
| processus frontalis ossis zygomatici | The process of the zygomatic bone which extends upward to form the lateral margin of the orbit and articulates with the frontal bone and greater wing of the sphenoid bone. Synonym: frontosphenoidal process, processus frontalis ossis zygomatici. (05 Mar 2000) |
| processus zygomaticus ossis frontalis | The massive projection of the frontal bone that joins the zygomatic bone to form the lateral margin of the orbit. Synonym: processus zygomaticus ossis frontalis. (05 Mar 2000) |
| spina nasalis ossis frontalis | A projection from the centre of the nasal part of the frontal bone, which lies between and articulates with the nasal bones and the perpendicular plate of the ethmoid. Synonym: spina nasalis ossis frontalis. (05 Mar 2000) |
| facies externa ossis frontalis | The convex outer surface of the frontal bone. Synonym: facies externa ossis frontalis. (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) |
| foramen caecum ossis frontalis | <anatomy> Blind or caecal foramen of the frontal bone; the blind foramen formed immediately anterior to the crista galli by a notch at the lower end of the frontal crest and its articulation with the ethmoid bone. It is insignificant postnatally, but gives passage to vessels during development. Synonym: foramen caecum ossis frontalis, blind foramen of frontal bone, caecal foramen of frontal bone.

| margo occipitalis ossis temporalis | That part of the temporal bone that articulates with the occipital squama. Synonym: margo occipitalis ossis temporalis. (05 Mar 2000) |
| margo parietalis ossis temporalis | The border of the squamous part of the temporal bone that articulates with the parietal bone. Synonym: margo parietalis ossis temporalis. (05 Mar 2000) |
| margo posterior partis petrosae ossis temporalis | The margin of the petrous part of the temporal bone that extends from the apex to the jugular notch; it articulates with the basal and jugular portions of the occipital bone. Synonym: margo posterior partis petrosae ossis temporalis. (05 Mar 2000) |
| margo sagittalis ossis parietalis | The medial border of the parietal bone entering into the sagittal suture. Synonym: margo sagittalis ossis parietalis. (05 Mar 2000) |
| margo squamosus ossis parietalis | The lateral border of the parietal bone that articulates with the squamous part of the temporal bone. Synonym: margo squamosus ossis parietalis. (05 Mar 2000) |
| margo superior partis petrosae ossis temporalis | The margin that separates the anterior and posterior surfaces of the petrous part of the temporal bone and the lateral part of the middle cranial fossa from the posterior cranial fossa. Synonym: margo superior partis petrosae ossis temporalis, crest of petrous part of temporal bone. (05 Mar 2000) |
