Myelination continues through the adolescent stage of life. Schwann cells supply the myelin for the peripheral nervous system, whereas oligodendrocytes, specifically of the interfascicular type, myelinate the axons of the central nervous system.t is an outgrowth of a type of glial cell. The production of the myelin sheath is called myelination. In humans, myelination begins in the 14th week of fetal development, although little myelin exists in the brain at the time of birth.
All CNS (central nervous system, i.e. brain and spinal cord) fibres are myelinated. The only difference between myelination in the CNS and the PNS (peripheral nervous system) is the type of cell responsible for myelination.In the PNS these are Schwann cells. Each of these wraps around and insulates a short length (about 1mm) of a single axon. In the CNS, oligodendrocytes provide myelination.These cells project to and wrap a portion of several axons so they also provide a kind of '3D scaffolding' as well as myelination.n the PNS these are Schwann cells.
