| secondary spiral lamina | A ridge on the outer wall of the first turn of the cochlea opposite the spiral lamina. Synonym: lamina spiralis secundaria, secondary spiral plate. (05 Mar 2000) |
|---|---|
| hook of spiral lamina | The upper hooklike termination of the bony spiral lamina at the apex of the cochlea. Synonym: hamulus laminae spiralis, hamulus cochleae, hook of spiral lamina. (05 Mar 2000) |
| spiral lamina | The bony plate which extends outwards from the modiolus. It is part of the structure which divides trhe cochlea into sections. (12 Dec 1998) |
| nuclear lamina | <cell biology> A fibrous protein network lining the inner surface of the nuclear envelope. The extent to which this system also provides a scaffold within the nucleus is controversial. Proteins of the lamina are lamins A, B and C, which have sequence homology to proteins of intermediate filaments. (18 Nov 1997) |
| superficial lamina | In a stratified structure, the outermost or topmost of the strata; the stratum nearest the surface. See: superficial layer of deep cervical fascia, superficial layer of the levator {palpebrae superioris muscle}, superficial layer of temporalis fascia. Synonym: lamina superficialis, superficial lamina. (05 Mar 2000) |
| deep lamina | In a stratified structure, the stratum which lies beneath all others, furthest from the surface. See: deep layer of levator palpebrae superioris muscle}, deep layer of temporalis fascia. Synonym: lamina profunda, deep lamina. (05 Mar 2000) |
| suprachoroid lamina | A layer of loose, pigmented connective tissue on the outer surface of the choroid, resembling and attached to the lamina fusca sclerae. Synonym: lamina suprachoroidea, ectochoroidea, suprachoroid layer, suprachoroidea. (05 Mar 2000) |
| 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) |
