Myelination definition of myelination by Medical dictionary

Web15 jul. 2014 · According to one early theory, CNS myelin forms by coalescence of intracytoplasmic membranes ( De Robertis et al., 1958 ), whereas others have suggested that myelin is formed by the fusion of many different glial processes from one or different oligodendrocytes ( Luse, 1956 ). Web9 aug. 2024 · Myelination, the insulating ensheathment of axons by oligodendrocytes, is thought to both optimize signal propagation and provide metabolic support.
