The myelin sheath is a layer of fat and protein that covers the axon of a neuron, or nerve cell.The axon, which is a long, thin projection, is designed to carry electrical signals from a neuron to other cells.he myelin sheath is a layer of fat and protein that covers the axon of a neuron, or nerve cell.
Myelin Production. Myelin is produced in your nerve tissues by helper cells called glial cells, which are located adjacent to the nerve cells. Glial cells secrete myelin as an extension of their own cell membranes, and the secreted myelin spirals around your nerve cell axons to form segments of the myelin sheath.n your brain and nerve tissue, cholesterol is required for the formation of the myelin sheath, a fatty material that surrounds long portions of nerve fibers. Myelin insulates nerve cells and enhances the passing of electrical signals throughout your nervous systemâs circuitry.
