| eminentia articularis ossis temporalis | 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) |

| fovea articularis superior atlantis | One of two concave articular surfaces on the superior aspect of the lateral masses of the atlas that articulate with the occipital condyles. Synonym: facies articularis superior atlantis, fovea articularis superior atlantis, superior articular pit of atlas. (05 Mar 2000) |
