Identify TRUE or FALSE 1. The cells that conduct messages towards the brain are the interneurons.2. Nerves impulses always travel to the brain through nerve fibers.3. The presence of myelin gives a nerve fiber its white color and increased rate of impulse transmission.4. Saltatory conduction involves Schwann cells and occurs at greater speed than onunmyelinated fibers.5. The neuron cannot be stimulated during the absolute refractory period.6. The speed of a nerve impulse is independent of the presence of myelin.7. The tightly packed coil of neurolemmocyte membrane that encircles certain kinds ofaxons is called a node.8. Depolarization of the membrane of a nerve cell occurs by the rapid influx of organic ions.9. In a resting neuron the outside is negatively charged.10. The interior surface of a membrane of a nonconducting neuron differs from the exteriorsurface in that the former is negatively charged and contains more sodium.
