Myelin Sheath In a neuron‚ the myelin sheath consists of fat-containing cells that insulate the axon from electrical activity. This can be compared such as the insulation of a house. The main purpose of the insulation is to increase the rate of transmission of signals in the neuron. There is a small gap between each myelin sheath cell along the axon. Since fat inhibits the proper agitation of electricity‚ the signals jump from one gap to another. The destruction or loss of the myelin sheath in

Composition and Formation of Myelin Sheath Molecular Neurobiology Myelin may be made by different cell types‚ varies in chemical composition and configuration‚ but performs the same insulating function. Myelin is about 40% water; the dry mass of myelin is about 70 - 85% lipids and about 15 - 30% proteins. Some of the proteins that make up myelin are myelin basic protein (MBP)‚ myelin oligodendrocyte glycoprotein (MOG)‚ and proteolipid protein (PLP). The primary lipid of myelin is a glycolipid called
