The Schmidt-Lanterman incisures are formed in the phase of "loose" myelin at 15-17 weeks of prenatal development with the formation of nodes of Ranvier. The formation of mature Schmidt-Lanterman incisure is completed in the second foetis period. Schmidt-Lanterman incisures distribution in nerve fibres of young men depends on fibre diameter. In the nerves of elderly people the distribution of the incisures in the internode doesn't depend on a fibre diameter. In the nerves of the elderly men the number of incisures is twice as much as that in the young people. The incisural ultrastructure in human nerve is similar to its structure in other mammals.
施密特-兰特尔曼切迹在产前发育15至17周的“疏松”髓鞘阶段形成，同时形成郎飞结。成熟的施密特-兰特尔曼切迹在胎儿第二个时期完成形成。年轻男性神经纤维中施密特-兰特尔曼切迹的分布取决于纤维直径。在老年人的神经中，切迹在结间的分布不取决于纤维直径。老年男性神经中的切迹数量是年轻人的两倍。人类神经中切迹的超微结构与其在其他哺乳动物中的结构相似。
