Multiple sclerosis is a disease in which demyelination occurs in neurones involved in coordinating muscle movement. Using your knowledge of nerve impulse generation and propagation, explain how nerve impulse generation and propagation would be affected in people who have multiple sclerosis. The explanation needs to be in the form of a step by step sequence of annotated drawings. This could be in the form of an annotated cartoon/picture strip. Compare this to nerve impulse generation and propagation in an individual who does not have multiple sclerosis.arrow_forward
