Web7 feb. 2024 · Whilst neurones have many dendrites, most cells only have one axon. Each axon is coated in myelin – a layer of insulating lipid. Myelin is formed by cells wrapping themselves around the nerve axon. In the CNS, this is performed by oligodendrocyte cells. In the PNS, Schwann cells are responsible for this action. Web11 okt. 2024 · When the myelinatiion process is complete, the Schwann cell covers the axon with many layers of plasma membranes, consisting mostly of lipids. 1 2 This covering is called a myelin sheath, and the axon is said to be myelinated.
