The myelin sheath is a layer that forms an insulating and protective coating around nerves. This sheath is fundamental for the functioning of the nervous system.
During neuronal firing, the part of the neuron that acts as an insulator and conductor to speed the electrical impulse as it travels down the axon is the MYELIN SHEATH.
This myelin layer is fundamental for the efficiency and velocity of the transmission of electrical impulses along nerves.
The damage of the myelin sheath is associated with different neuronal disorders (e.g., multiple sclerosis).
