A bundle of axons (nerve fibers) in the CNS is called a tract. In the PNS this bundle is called a nerve. Besides from neurons, there are other nervous system cells, for … NettetMyelin. The insulation for axons in the nervous system is provided by glial cells, oligodendrocytes in the CNS, and Schwann cells in the PNS. Whereas the manner in which either cell is associated with the axon segment(s) that it insulates is different, the means of myelinating an axon segment is mostly the same in the two situations. cydia impactor erkennt iphone nicht

"NettetOligodendrocytes, shown in Figure 16.8 b form myelin sheaths around axons in the CNS. One axon can be myelinated by several oligodendrocytes, and one oligodendrocyte can provide myelin for multiple neurons. This is distinctive from the PNS where a single Schwann cell provides myelin for only one axon as the entire Schwann cell surrounds … " - Insulates axons in the pns
