| lingula sphenoidalis | A slender process projecting posteriorly between the body and greater wing of the sphenoid bone, on either side, forming the lateral margin of the carotid groove. In the dry skull, it projects into the foramen laccrum. (05 Mar 2000) |

| lingula | Origin: L, a little tongue. 1. <anatomy> A tonguelike process or part. 2. <zoology> Any one of numerous species of brachiopod shells belonging to the genus Lingula, and related genera. See Brachiopoda, and Illustration in Appendix. <geology> Lingula flags, a group of strata in the lower Silurian or Cambrian system of Wales, in which some of the layers contain vast numbers of a species of Lingula.

| lingula cerebelli | Synonym: lingula of cerebellum. (05 Mar 2000) |
| lingula mandibulae | A pointed tongue of bone overlapping the mandibular foramen, giving attachment to the sphenomandibular ligament. Synonym: lingula mandibulae, mandibular tongue, Spix's spine. (05 Mar 2000) |
| lingula of cerebellum | A tongue-shaped sequence of flattened cerebellar folia forming the anterior (or superior) extreme of the cerebellar vermis, extending forward on the surface of the superior medullary velum between the two emerging superior cerebellar peduncles. Synonym: lingula cerebelli, lingua cerebelli, tongue of cerebellum. (05 Mar 2000) |
| lingula of left lung | An inferomedial projection from the anterior aspect of the upper lobe of the left lung which bounds the cardiac notch inferiorly. Synonym: lingula pulmonis sinistri. (05 Mar 2000) |
| lingula of mandible | A pointed tongue of bone overlapping the mandibular foramen, giving attachment to the sphenomandibular ligament. Synonym: lingula mandibulae, mandibular tongue, Spix's spine. (05 Mar 2000) |
| lingula pulmonis sinistri | An inferomedial projection from the anterior aspect of the upper lobe of the left lung which bounds the cardiac notch inferiorly. Synonym: lingula pulmonis sinistri. (05 Mar 2000) |
| ala major ossis sphenoidalis | Strong squamous processes extending in a broad superolateral curve from the body of the sphenoid bone. The greater wing presents these suraces (facies): 1) cerebral surface: forms anterior third of the floor of the lateral portions of the middle cranial fossa; 2) temporal surface: forms the deepest portion of the temporal fossa; 3) infratemporal surface, forms the "roof" of the infratemporal fossa; 4) orbital surface: forms posterolateral wall of orbit. The greater wing forms the inferior border of the supraorbital fissure, and is perforated at its root by foramina rotundum ovale, and spinosum and the pterygoid canal. Synonym: ala major ossis sphenoidalis, ala temporalis. (05 Mar 2000) |
| ala minor ossis sphenoidalis | 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) |
| angulus sphenoidalis ossis parietalis | The anterior inferior angle of the parietal bone. Synonym: angulus sphenoidalis ossis parietalis, sphenoid angle, sphenoidal angle, Welcker's angle. (05 Mar 2000) |
| apertura sinus sphenoidalis | One of the pair of openings in the body of the sphenoid bone through which the sphenoid sinuses communicate with the sphenoethmoidal recess of the nasal cavity. Synonym: apertura sinus sphenoidalis, sphenoidal sinus aperture. (05 Mar 2000) |
| margo frontalis ossis sphenoidalis | The margin of the greater wing of the sphenoid bon that articulates with the frontal bone. Synonym: margo frontalis ossis sphenoidalis. (05 Mar 2000) |
| margo parietalis ossis sphenoidalis | The margin of the greater wing of the sphenoid that articulates with the parietal bone. Synonym: margo parietalis ossis sphenoidalis. (05 Mar 2000) |
| margo sphenoidalis ossis temporalis | The part of the border of the squamous part of the temporal bone that articulates with the greater wing of the sphenoid. Synonym: margo sphenoidalis ossis temporalis. (05 Mar 2000) |
| margo squamosus ossis sphenoidalis | The margin of the greater wing of the sphenoid bone that articulates with the squamous part of the temporal bone. Synonym: margo squamosus ossis sphenoidalis. (05 Mar 2000) |
