| 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) |
| articulation of pisiform bone | The synovial joint between the pisiform and triquetrum; it is separate from the other intercarpal joints. Synonym: articulatio ossis pisiformis, articulation of pisiform bone. (05 Mar 2000) |
| basal bone | The osseus tissue of the mandible and maxillae except the alveolar processes. (05 Mar 2000) |
| basal part of occipital bone | The part of the occipital bone that lies anterior to the foramen magnum and joins with the body of the sphenoid bone. Synonym: pars basilaris ossis occipitalis, basal part of occipital bone, basilar apophysis, basilar process of occipital bone, basilar process, basiocciput. (05 Mar 2000) |
| base of hyoid bone | The body of the hyoid bone, from which the greater and lesser horns extend. Synonym: corpus ossis hyoidei, base of hyoid bone, basihyal, basihyoid. (05 Mar 2000) |
| base of metacarpal bone | The expanded proximal extremity of each metacarpal that articulates with one or more of the distal row of carpal bones. Synonym: basis ossis metacarpalis. (05 Mar 2000) |
| base of metatarsal bone | The expanded proximal extremity of each metatarsal bone; it articulates with one or more of the distal row of tarsal bones. Synonym: basis ossis metatarsalis. (05 Mar 2000) |
| basilar bone | The developmental basilar process of the occipital bone which unites with the condylar portions in about the fourth or fifth year, becoming the basilar part of the occipital bone. Synonym: basioccipital bone, os basilare. (05 Mar 2000) |
| basilar part of the occipital bone | The part of the occipital bone that lies anterior to the foramen magnum and joins with the body of the sphenoid bone.

| basilar process of occipital bone | The part of the occipital bone that lies anterior to the foramen magnum and joins with the body of the sphenoid bone. Synonym: pars basilaris ossis occipitalis, basal part of occipital bone, basilar apophysis, basilar process of occipital bone, basilar process, basiocciput. (05 Mar 2000) |
| basioccipital bone | The developmental basilar process of the occipital bone which unites with the condylar portions in about the fourth or fifth year, becoming the basilar part of the occipital bone. Synonym: basioccipital bone, os basilare. (05 Mar 2000) |
