It helps electrical signals move fast and smoothly from one nerve cell to another. It preserves the strength of the electrical message as it travels If you have a disease that damages your myelin sheath, your nerves won't be able to send and receive messages as they should. The most common...

For example, the myelin sheath helps to support the metabolic activity of nerve cells, and it is important for regulating salt and water levels in the cell.How is the myelin sheath linked to MS?In MS, the immune system launches an inflammatory attack in the central nervous system. This ...
This occurs because the myelin sheath inhibits ion movement along the insulated area of the axon, encouraging the diffusion of ions along the axon to reach the next node. At the node, the high concentration of ion channels enables rapiddepolarisationand action potential generation. ...
Answer to: Schwann cells form the myelin sheath around multiple axons at once and the neurilemma which aids in axon regeneration after injury. a...

Computer-assisted measurements of relative myelin sheath thickness (the g ratio) were made in 11 peripheral nerves of the rat. The scatter diagrams showed nerve-specific variations in the distribution of relative myelin sheath thickness. Myelinated fibers of less than 3.5 μm axon diameter had rel...
