Function of the myelin
WebMyelin is an important part of neuron cells and provides insulation allowing the neuron's action potential to travel faster and more consistently. In order to provide insulation, multiple layers of closely opposing membrane are wrapped around the axon. 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 …

Webmyelin. Schwann cell, also called neurilemma cell, any of the cells in the peripheral nervous system that produce the myelin sheath around neuronal axons. Schwann cells are named after German physiologist Theodor Schwann, who discovered them in the 19th century. These cells are equivalent to a type of neuroglia called oligodendrocytes, which ... WebApr 12, 2024 · Myelin protein zero (MPZ or P0) is a major transmembrane protein expressed in peripheral compact myelin and functions to glue membranes to form multiple layered membranes characteristic of myelin.
