124 Describe two ways a cell can become hyperpolarized.
125 I.K+ efflux when K+ becomes more permeable, making the cell more negative II.Influx of Cl- making inside of cell more negative
126 Explain why multiple sclerosis negatively affects motor control.
127 I.This is a demyelinating disease. Conduction in Myelinated Axons are faster. Damage to Myelin means ion flow out of the cytoplasm and slower conduction because the amount of membrane in contact with ECF is increased.
