DisplayPort connector. DisplayPort is a digital display interface developed by the Video Electronics Standards Association (VESA). The interface is primarily used to connect a video source to a display device such as a computer monitor, though it can also be used to carry audio, USB, and other forms of data.
myelin sheath. n. The insulating envelope of myelin that surrounds the core of a nerve fiber or axon and that facilitates the transmission of nerve impulses, formed from the cell membrane of the Schwann cell in the peripheral nervous system and from oligodendroglia cells.Also called medullary sheath..

Also called medullary sheath.
Many glial cells lined up along an axon are required to fully myelinate and insulate a long nerve cell. The composition of myelin is approximately 30 percent protein, 27 percent cholesterol and 43 percent phospholipid.Myelin production is absolutely dependent on cholesterol synthesis in the glial cells.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.
