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.. 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.
The myelin sheath is a covering of the neuron (nerve cell) made by schwann cells wrapping themselves around the neuron down the length of the axon.he main purpose of the myelin sheath is to speed up the conduction velocity of nerve impulses. While there is an electrical charge involved in signals along nerves, it's not the same as a current along a wire. Instead, small channels in the membrane of the neruon open up, and ions flood through.
