    True
  2. Ependymal cells engulf and destroy microbes and cellular debris in inflamed or degenerating brain tissue
    False
  3. The afferent nervous system consist of all outgoing motor pathways

  4. Oligodendrocytes form myelin sheath around nerve fibers in the CNS
    True
  5. In a myelinated fiber, the action potential jump from one node of Ranvier to the next
    True
  6. Meningitits refers to inflammation of the brain
    False
