Does myelin sheath transmits impulses from one nuron to another?

No. The myelin sheath does not transmit impulses from one neuron to another. Instead, it acts as an insulator, increasing the speed at which electrical impulses (action potentials) are conducted along the axon of a neuron. By reducing the leakage of ions and increasing the resistance of the membrane, the myelin sheath allows for saltatory conduction of action potentials, where the electrical impulse "jumps" from one node of Ranvier (unmyelinated region) to the next, effectively speeding up the transmission of signals over long distances.
