| 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) |
| articular tubercle of temporal bone | Articular eminence of the temporal bone which bounds the mandibular fossa anteriorly; it forms the anterior root of the zygomatic process; it is enclosed by the articular capsule of the temporomandibular joint with the articular fossa; the head of the mandible (and intervening articular disc) move onto the articular tubercle to allow full depression of mandible (opening of mouth). Synonym: tuberculum articulare ossis temporalis, articular eminence of temporal bone, eminentia articularis ossis temporalis, tuber zygomaticum. (05 Mar 2000) |

| mastoid part of the temporal bone | The portion of the petrous part of the temporal bone bearing the mastoid process. Synonym: pars mastoidea ossis temporalis. (05 Mar 2000) |
| petrous part of temporal bone | The part of the temporal bone that contains the structures of the inner ear and the second part of the internal carotid artery; in antenatal life it appears as a separate ossification centre. Synonym: pars petrosa ossis temporalis, periotic bone, petrosal bone, petrous pyramid. (05 Mar 2000) |
