| simple myopic astigmatism | That form of astigmatism in which one meridian is myopic and the one at right angle to it is without refractive error. Synonym: simple myopic astigmatism. (05 Mar 2000) |

| simple necrosis | A stage of coagulation necrosis; the occurrence of a coarsely granular or hyaline change in the cytoplasm, and the lack of a recognizable nucleus, with the general configuration of the dead cells being relatively unchanged. (05 Mar 2000) |
| simple partial seizure | A partial seizure that is not associated with impairment of consciousness. (05 Mar 2000) |
| simple protein | Protein that yields only alpha-amino acids or their derivatives by hydrolysis; e.g., albumins, globulins, glutelins, prolamines, albuminoids, histones, protamines. Compare: conjugated protein. (05 Mar 2000) |
| simple pulmonary eosinophilia | Pulmonary infiltrates seen as transient migratory shadows on the chest X-ray, accompanied by blood eosinophilia; often symptomless, but there may be cough, fever, and breathlessness; most cases are due to worm infestation, especially by Ascaris lumbricoides; a few cases follow administration of drugs. Synonym: Loffler's syndrome. (05 Mar 2000) |

| squamous epithelium | <pathology> An epithelium in which the cells are flattened. May be simple (e.g. Endothelium) or stratified (e.g. Epidermis). (18 Nov 1997) |
| stratified epithelium | <pathology> An epithelium composed of multiple layers of cells, only the basal layer being in contact with the basal lamina. The basal layer is of stem cells that divide to produce the cells of the upper layers, in skin, these become heavily keratinised before dying and being shed as squames. Stratified epithelia usually have a mechanical or protective role. (18 Nov 1997) |
| stratified squamous epithelium | An epithelium consisting of several layers of keratin containing cells in which the surface cells are flattened and scale-like and the deeper cells are polyhedral in form. Keratin filaments become progressively more abundant toward the surface, which on the dry surfaces of the body may consist of a layer of dead corneocytes. (05 Mar 2000) |
| sulcular epithelium | The stratified squamous epithelium lining the inner aspect of the soft tissue wall of the gingival sulcus. Synonym: sulcular epithelium. (05 Mar 2000) |
| surface epithelium | A layer of celomic epithelial cells covering the gonadal ridges as they are formed on the medial border of the mesonephroi near the root of the mesentery, the mesothelial covering of the definitive ovary. (05 Mar 2000) |
