5 True/False questions
Sodium Potassium Pumps → How does the membrane maintain the difference in electrical charge established by diffusion of ions?
Myelin Sheath → insulates the nerve fibers
Synapse → junction or point of close contact between neurons
Oligodendrocytes → Form the myelin in the brain and spinal cord
Relative Refractory period → What period is it during repolarization, the membrane may be stimulated if a very strong stimulus is used?
