| stratum lucidum | A layer of lightly staining corneocytes in the deepest level of the stratum corneum; found primarily in the thick epidermis of the palmar and plantar skin. Synonym: clear layer of epidermis. (05 Mar 2000) |

| stratum moleculare | Synonym: molecular layer. (05 Mar 2000) |
| stratum moleculare cerebelli | The outer lamina of the cortex, containing the cell bodies and dendrites of Purkinje cells, the axons of the granule cells, and the cell bodies, dendrites, and axons of basket cells. Synonym: stratum moleculare cerebelli, molecular layer of cerebellar cortex. (05 Mar 2000) |
| stratum moleculare retinae | Name applied to each of the plexiform layers of the retina. Synonym: stratum moleculare retinae. (05 Mar 2000) |
| stratum neuroepitheliale retinae | The outermost layer of the cerebral layer of retina, composed of the primary receptor cells of the retina; the stratum consists of two sublayers: 1) an external layer made up of the rods and cones, the photosensitive processes of the receptor cells, and 2) the external nuclear layer containing the cell bodies of these cells; the external limiting membrane forms a perforated supporting plate between the two sublayers; the name refers to the fact that the retinal receptor cells are a specialised form of (epithelial) ependyma cell and thus, in a sense, are comparable to the neuroepithelial cells (e.g., hair cells) of other sense organs. Synonym: external nuclear layer of retina, stratum neuroepitheliale retinae, stratum nucleare externum retinae. (05 Mar 2000) |
| stratum neuronorum piriformium | The layer of Purkinje cells between the molecular and granular layers of the cerebellar cortex. Synonym: stratum neuronorum piriformium, ganglionic layer of cerebellar cortex, layer of piriform neurons, Purkinje's layer, stratum gangliosum cerebelli. (05 Mar 2000) |
| stratum nucleare externum et internum retinae | The outer nuclear layer, layer 4, of the retina, neuroepithelial layer of retina, and the inner layer, layer 6, of the retina, ganglionic layer of retina. Synonym: granular layers of retina, stratum nucleare externum et internum retinae. (05 Mar 2000) |
| stratum nucleare externum retinae | The outermost layer of the cerebral layer of retina, composed of the primary receptor cells of the retina; the stratum consists of two sublayers: 1) an external layer made up of the rods and cones, the photosensitive processes of the receptor cells, and 2) the external nuclear layer containing the cell bodies of these cells; the external limiting membrane forms a perforated supporting plate between the two sublayers; the name refers to the fact that the retinal receptor cells are a specialised form of (epithelial) ependyma cell and thus, in a sense, are comparable to the neuroepithelial cells (e.g., hair cells) of other sense organs. Synonym: external nuclear layer of retina, stratum neuroepitheliale retinae, stratum nucleare externum retinae. (05 Mar 2000) |
| stratum nucleare internum retinae | The intermediate layer of neurons in the retina composed largely of bipolar cells. Synonym: internal nuclear layer of retina, stratum ganglionare retinae, stratum nucleare internum retinae. (05 Mar 2000) |
| stratum opticum | A layer of white matter interspersed with nerve-cell bodies, immediately below the superficial gray layer of the superior colliculus, composed of myelinated fibres originating in the retina and striate cortex, the inner layer of the retina, consisting of the fibres originating from the cells of the ganglionic layer of optic nerve; in their further course these fibres combine to form the optic nerve or optic tract. Synonym: stratum opticum. (05 Mar 2000) |
| stratum papillare corii | The more superficial layer of the corium whose papillae interdigitate with the epidermis. Synonym: corpus papillare, papillary layer. (05 Mar 2000) |
| stratum pigmenti bulbi | The outer layer of the retina, consisting of pigmented epithelium. Synonym: ectoretina, stratum pigmenti bulbi, stratum pigmenti retinae, tapetum nigrum, tapetum oculi. (05 Mar 2000) |
| stratum pigmenti corporis ciliaris | The continuation of the pigment layer of the retina onto the posterior aspect of the ciliary body. Synonym: pigmented layer of ciliary body. (05 Mar 2000) |
| stratum pigmenti iridis | The double layer of pigmented epithelium on the posterior surface of the iris. Synonym: pigmented layer of iris. (05 Mar 2000) |
| stratum pigmenti retinae | The outer layer of the retina, consisting of pigmented epithelium. Synonym: ectoretina, stratum pigmenti bulbi, stratum pigmenti retinae, tapetum nigrum, tapetum oculi. (05 Mar 2000) |
