WebThe development of Schmidt-Lanterman incisures was investigated in the rat sural nerve during an active phase of postnatal myelination (5-21 days post partum). Two distinct populations of incisures were recognised and the following nomenclature for their developmental stages is proposed. Myelin incisures (also known as Schmidt-Lanterman clefts, Schmidt-Lanterman incisures, clefts of Schmidt-Lanterman, segments of Lanterman, medullary segments), are small pockets of cytoplasm left behind during the Schwann cell myelination process.
