The statement, "The lipoprotein sheath which surrounds many neurons is defined as the myelin sheath" is a true statement.
The myelin sheath is defined as a greatly extended and modified plasma membrane wrapped around the nerve axon in a spiral fashion. The myelin membranes are originated from Schwann cells and are also a part of the Schwann cells present in the peripheral nervous system (PNS) and the oligoden-droglial cells in the central nervous system (CNS).
Myelin is basically an insulating layer, or sheath that forms around nerves, including those in the brain and spinal cord. Myelin is made up of protein and fatty substances. This myelin sheath helps by allowing electrical impulses to transmit quickly and efficiently along the nerve cells.
