What is the function of the myelin sheath?Select the correct definitionSpeeds up conduction of an action potentialLocation of protein synthesis and cellular machineryReceives incoming signals from other neuronsRegulates chemical environment for signalingRegeneration of action potential

The myelin sheath enables faster nerve signal transmissionQuestion 7Select one:TrueFalse

Which part of a motor neurone is surrounded by the myelin sheath

Myelin is critical to nervous system function because multiple choice 1it provides insulation around axons so as to greatly speed up neural impulses.it is used by neurons as an emergency energy source during times of low blood glucose.it is the source of acetylcholine and thus critical to neuronal signal propagation. 2. The cells of the nervous system that produce myelin are the multiple choice 2unipolar neurons.oligodendrocytes.astrocytes.microglia.
