Un axone myélinisé du systeme nerveux periphérique

Les incisures de Schmidt-Lanterman sont des incisures transversales (visualisables en microscopie électronique) situées sur la myéline dite non compacte des axones situés au niveau du système nerveux périphérique. Ces incisures sont dues à la persistance du cytoplasme de la cellule de Schwann lors de l'accolement des faces cytoplasmiques de la membrane plasmique de ces cellules.
