Myelin sheaths protect nerve axons from damage. These sheaths are a lipid-rich stretch of the plasma membrane formed in the peripheral nervous system (PNS) by Cell bodies and in the central nervous system by oligodendrocytes (CNS). The myelin sheath is periodically broken all along length of the axon by specific areas known as nodes of Ranvier, which are needed for action potential propagation along the axon. The Ranvier nodes are critical in the speed and timing of impulse transport from one neuron to another, and variations in size or activity have the potential to compromise a neuron's efficacy, resulting in the emergence of neurological diseases.
