| lesser wing of sphenoid bone | 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) |
| lesser zygomatic muscle | <anatomy, muscle> Origin, zygomatic bone posterior to zygomaticomaxillary suture; insertion, orbicularis oris of upper lip; action, draws upper lip upward and outward; nerve supply, facial. Synonym: musculus zygomaticus minor, caput zygomaticum quadrati labii superioris, lesser zygomatic muscle. (05 Mar 2000) |
| accessory tubercle | A small apophysis at the posterior part of the base of the transverse process of each of the lumbar vertebrae. Synonym: processus accessorius, accessory tubercle. (05 Mar 2000) |
| acoustic tubercle | The slight prominence of the floor of the lateral recess of the fourth ventricle, corresponding to the underlying cochlear and vestibular nuclei. Synonym: acoustic tubercle, trigonum acustici. (05 Mar 2000) |
| adductor tubercle | The prominence above the medial epicondyle of the femur to which the tendon of the adductor magnus attaches. Synonym: tuberculum adductorium. (05 Mar 2000) |

| anterior tubercle of cervical vertebrae | The anterior projection from the transverse process. Synonym: tuberculum anterius vertebrarum cervicalium. (05 Mar 2000) |
| anterior tubercle of thalamus | anterior thalamic tubercle |
| articular surface of tubercle of rib | An oval facet on the inferomedial part of the tubercle of a rib for articulation with a facet on the transverse process of a vertebra. Synonym: facies articularis tuberculi costae. (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) |
