| Schmidt-Lanterman clefts | Funnel-shaped interruptions in the regular structure of the myelin sheath of nerve fibres, formerly interpreted as actual breaks in the sheath but shown by electron microscopy to correspond each to a strand of cytoplasm locally separating the two otherwise fused oligodendroglial (or, in peripheral nerves, Schwann cell) membranes composing the myelin sheath.

| Schmidt-Thannhauser method | A method for fractionation of nucleic acid, based upon the fact that RNA but not DNA is hydrolyzed to nucleotides by alkali; RNA can be hydrolyzed in about 2 hours in 0.75 n NaOH, but 18 hours and 0.3 n NaOH usually are used. (05 Mar 2000) |
| schmorl node | <radiology> Chondrification defects where periosteal vessels penetrate cartilage plates of disc, Xray: concave defects at upper and lower vertebral endplates with sharp margins produced by herniation of disc material, MRI: similar signal intensity as disc, low signal intensity of rim, associated with narrow disc space Differential diagnosis: SHOOT, Scheuermann disease, hyperparathyroidism, osteoporosis, osteomalacia, trauma (12 Dec 1998) |

| Schmorl's ferric-ferricyanide reduction stain | <technique> A stain to test for reducing substances in tissues, including melanin, argentaffin granules, thyroid colloid, keratin, keratohyalin, and lipofuscin pigments; ferricyanide is converted into ferrocyanide which is converted to insoluble Prussian blue in the presence of ferric ions.
