Discuss the function of the myelin sheath
WebThe myelin accelerates the speed at which a nerve signal travels along a cell. Unfortunately, there is a limit to how much myelin you can develop on any given nerve axon, but a nerve that is fully loaded with myelin can transmit its signal 100 times faster than a minimally myelinated nerve cell. WebThe myelin sheath formed by Schwann cells produces saltatory conduction, and these rapid electrical signals control motor and sensory functioning in the service of survival in mammals. Schwann cells play roles not only in myelin sheath formation but also as modulators of nerve degeneration and regeneration.

WebOct 24, 2016 · Myelin is a key evolutionary acquisition that underlay the development of the large, complex nervous systems of all hinged-jaw vertebrates. By promoting rapid, efficient nerve conduction, myelination also made possible the development of the large body size of these vertebrates.
The myelin sheath has three functions: 1. Its fatty-protein coating provides protective insulation for your nerve cell, like the plastic insulation covering that encases the wires of an electrical cord. 2.
