| lamina dorsalis | The dorsal division of the lateral walls of the neural tube in the embryo; it gives rise to neurons relaying afferent impulses to higher centres; in the adult such neurons compose the sensory nuclei of the spinal cord and brainstem. Synonym: lamina alaris, alar plate of neural tube, dorsolateral plate of neural tube, lamina dorsalis, wing plate. (05 Mar 2000) |

| lamina elastica anterior | A transparent homogeneous acellular layer, 6 to 9 um thick, lying between the basal lamina of the outer layer of stratified epithelium and the substantia propria of the cornea; considered to be a basement membrane. Synonym: lamina limitans anterior corneae, anterior elastic layer, Bowman's membrane, lamina elastica anterior, limiting layers of cornea. (05 Mar 2000) |
| lamina elastica posterior | Elastic laminae of arteries, 1) external: the layer of elastic connective tissue lying immediately outside the smooth muscle of the tunica media; 2) internal: a fenestrated layer of elastic tissue of the tunica intima. Synonym: elastic layers of arteries, Henle's fenestrated elastic membrane, posterior limiting layer of cornea. (05 Mar 2000) |
| lamina episcleralis | 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) |

| lamina fibroreticularis | A layer of the basement membrane in continuity with associated connective tissue; it is often discontinuous and may be lacking entirely in some cases. (05 Mar 2000) |
| lamina fusca of sclera | An exceedingly delicate layer of loose, pigmented connective tissue on the inner surface of the sclera, connecting it with the choroid. Synonym: lamina fusca sclerae, brown layer, membrana fusca. (05 Mar 2000) |
| lamina fusca sclerae | An exceedingly delicate layer of loose, pigmented connective tissue on the inner surface of the sclera, connecting it with the choroid. Synonym: lamina fusca sclerae, brown layer, membrana fusca. (05 Mar 2000) |
