12. 10. What type of cell is myelin? A) neuron B) glial

13. 11. What is the function of myelin in nerve cells
11. What is the function of myelin in nerve cells? A) decrease the speed of nerve transmission B) increase the speed of nerve transmission C) generate action potentials D) pass electrical signal from cell to another cell E) increase the magnitude of the action potential

14. 12. In myelinated axons, where are action potentials generated
12. In myelinated axons, where are action potentials generated? A) Node of Ranvier B) cell body C) dendrites D) underneath the myelin
13. Where, then, are voltage gated sodium channels concentrated in myelinated axons?
A) Node of Ranvier B) cell body C) dendrites D) underneath the myelin

16. 14. What happens to myelin in people who suffer from multiple sclerosis? A) breaks down B) builds up too much C) seals up Node of Ranvier
15. Why is there an elevated level of myelin basic protein in the cerebrospinal fluid?

17. 16. What would be the effect on action potential conduction at a region of axon where the disease had its effect? A) increase action potential conduction B) decrease action potential conduction C) no change to action potential conduction
17. What effect would this have on the coordination of movements if this took place in areas involved in motor control of finger movements?
