| lamina rostralis | 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) |
| lamina septi pellucidi | One of the two thin layers of the transparent septum, which extend from the corpus callosum to the fornix; often separated from each other by a space, the cavity of septum pellucidum. Synonym: lamina septi pellucidi. (05 Mar 2000) |
| lamina superficialis | 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) |
| lamina superficialis fasciae cervicalis | The part of the cervical fascia investing the sternocleidomastoid and trapezius muscles and completely encircling the neck. Synonym: lamina superficialis fasciae cervicalis, investing fascia, superficial layer of deep cervical fascia. (05 Mar 2000) |
| lamina superficialis fasciae temporalis | The superficial part of the temporal fascia attaching to the lateral surface of the zygomatic arch. Synonym: lamina superficialis fasciae temporalis. (05 Mar 2000) |
| lamina superficialis musculi levatoris palpebrae superioris | <anatomy> The superficial fibres of the levator muscle of the superior eyelid which are inserted into the skin of the superior eyelid. Synonym: lamina superficialis musculi levatoris palpebrae superioris. (05 Mar 2000) |
| lamina suprachoroidea | 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) |
| lamina supraneuroporica | That part of the choroid membrane of the third ventricle that forms the roof of the foramen of Monro. (05 Mar 2000) |
| lamina tecti mesencephali | 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) |
| lamina terminalis cerebri | A thin plate passing upward from the optic chiasm and forming the rostral boundary of the third ventricle; membrane closing the rostral neuropore. Synonym: lamina terminalis cerebri, lamina cinerea, terminal plate, velum terminale. (05 Mar 2000) |
| lamina terminalis of cerebrum | A thin plate passing upward from the optic chiasm and forming the rostral boundary of the third ventricle; membrane closing the rostral neuropore. Synonym: lamina terminalis cerebri, lamina cinerea, terminal plate, velum terminale. (05 Mar 2000) |
| lamina tragi | A longitudinal curved plate of cartilage, the beginning of the cartilaginous portion of the external acoustic meatus. Synonym: lamina tragi. (05 Mar 2000) |
| lamina vasculosa choroideae | <anatomy> The outer portion of the choroid of the eye containing the largest blood vessels. Synonym: lamina vasculosa choroideae, Haller's vascular tissue, uvaeformis, vascular layer of choroid coat of eye, vascular layer. (05 Mar 2000) |
| lamina ventralis | The ventral division of the lateral walls of the neural tube in the embryo; it contains neuroblasts giving rise to somatic and visceral motor neurons. Synonym: lamina basalis, basal plate of neural tube, lamina ventralis, ventral plate of neural tube. (05 Mar 2000) |
