| membranous lamina of cartilaginous auditory tube | The connective tissue membrane that, with the lateral lamina, completes the lateral and inferior walls of the cartilaginous part of the auditory tube. Synonym: lamina membranacea cartilaginis tubae auditivae, membranous layer. (05 Mar 2000) |

| periclaustral lamina | A thin lamina of white substance separating the claustrum from the putamen. It joins the internal capsule at either extremity of the putamen, forming a capsule of white matter external to the lenticular nucleus. Synonym: capsula externa, periclaustral lamina. (05 Mar 2000) |
| rostral lamina | A whitish line appearing on perfectly median sections of the brain as a thin bridge connecting the rostrum of the corpus callosum with the lamina terminalis; the rostral lamina contains no commissural fibres; instead, it corresponds to the line along which the pia mater reflects from the medial surface of one hemisphere to that of the other. Synonym: lamina rostralis, rostral layer, teniola corporis callosi. (05 Mar 2000) |
| cribrous lamina | The portion of the sclera through which pass the fibres of the optic nerve. Synonym: cribrous lamina, perforated layer of sclera. (05 Mar 2000) |
| hamulus 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) |
| primary dental lamina | dental ledge |
| 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) |
