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.
In between the myelin sheaths are what is called Nodes of Ranvier. So if you follow propagation of an action potential you will see that it starts with the addition of charges through the dendrites into the soma (cell body) and into the axonal hillock.he main purpose of myelin is to cover neuron â¦ cells so that it can conduct action potential more quickly. If you examine a myelinated neural axon within peripheral nervous system, you will see Schwann cells that cover the cell's axon with myelin sheaths.
