| dental lamina | dental ledge |
|---|---|
| dental lamina cyst | A small keratin-filled cyst, usually multiple, on the alveolar ridge of newborn infants; derived from remnants of the dental lamina. (05 Mar 2000) |
| dentogingival lamina | dental ledge |
| quadrigeminal lamina | The roofplate of the mesencephalon formed by the quadrigeminal bodies. Synonym: lamina tecti mesencephali, tectum mesencephali, lamina quadrigemina, quadrigeminal lamina, quadrigeminal plate. (05 Mar 2000) |
| internal medullary lamina | See: medullary laminae of thalamus. (05 Mar 2000) |
| iridopupillary lamina | Embryonic precursor of the anterior stroma of the iris which forms the inner (posterior or deep) wall of the primary anterior chamber of the eye. Its central portion becomes attenuated as the pupillary membrane (membrane pupillaris ). (05 Mar 2000) |
| orbital lamina of ethmoid bone | A thin plate of ethmoid bone forming part of the medial wall of the orbit and the lateral wall for the ethmoidal labyrinth. Synonym: lamina orbitalis ossis ethmoidalis, lamina papyracea, orbital lamina of ethmoid bone, orbital layer of ethmoid bone, orbital plate, paper plate, papyraceous plate. (05 Mar 2000) |
| osseous spiral lamina | A double plate of bone winding spirally around the modiolus dividing the spiral canal of the cochlea incompletely into two, scala tympani and scala vestibuli; between the two plates of this lamina the fibres of the cochlear nerve reach the spiral organ (of Corti). Synonym: lamina spiralis ossea, spiral plate. (05 Mar 2000) |
| episcleral lamina | The delicate moveable layer of loose connective tissue between the external surface of the sclera and the fascial sheath of the eyeball. Synonym: lamina episcleralis. (05 Mar 2000) |
| epithelial lamina | The layer of modified ependymal cells that forms the inner layer of the tela choroidea, facing the ventricle. Synonym: lamina epithelialis, epithelial choroid layer, lamina choroidea epithelialis, lamina choroidea. (05 Mar 2000) |
| tympanic labium of limbus of spiral lamina | The lower, long periosteal extension of the limbus laminae spiralis osseae that rests on the basilar lamina of the spiral organ (of Corti). Synonym: labium limbi tympanicum laminae spiralis, tympanic lip of limbus of spiral lamina. Labium urethrae, one of the two lateral margins of the external urethral orifice of the female. (05 Mar 2000) |
| tympanic lip of limbus of spiral lamina | The lower, long periosteal extension of the limbus laminae spiralis osseae that rests on the basilar lamina of the spiral organ (of Corti). Synonym: labium limbi tympanicum laminae spiralis, tympanic lip of limbus of spiral lamina. Labium urethrae, one of the two lateral margins of the external urethral orifice of the female.

| fibrous lamina | Alternative name for the nuclear lamina, the region lying just inside the inner nuclear membrane. (18 Nov 1997) |
| labiogingival lamina | A band of ectodermal epithelial cells growing into the mesenchyme of the embryonic jaws between the developing lip and the growing gingival elevation; it later opens to form the labiogingival groove. (05 Mar 2000) |
| lamina | Flat sheet, as in basal lamina. (18 Nov 1997) |
