Clinical considerations from axon-myelin relationship in human inferior alveolar nerve.
A histological study analysed the axon-myelin relationships in human inferior alveolar nerve fibres in both transverse and longitudinal sections. Observations on fibres cut in transverse section showed variation in myelin thickness upon axons having approximately the same diameter. Large diameter axons had relatively thinner myelin sheaths than small-diameter axons. A longitudinal reconstruction of a 470 micron length of fibre demonstrated the presence of 13 Schmidt-Lantermann clefts. The surgical and clinical implications of these finding are discussed.
