Mr. Harrison is an 82-year-old bedridden gentleman who has discovered a new interest in learning about his body. While being tended by the visiting nurse, he remarks that the supporting cells in nervous tissue (such as Schwann cells and oligodendrocytes) act like the rubber coating around household wiring. What does he mean by this analogy?

Match the neuroglia with the correct function: A. Satellite cells B. Schwann Cells C. Oligodendrocytes D. Ependymal E. Microglia F. Astrocytes 1. Cells that produce the myelin in the PNS. 2. Cells that produce myelin in the CNS 3. Phagocytes that dispose debris like dead brain cells and bacteria 4. Anchors and braces neurons with cellular projections 5. Cells have cilia that help circulate the cerebrospinal fluid 6. Cells help cushion and protect neurons in the PNS 7. Cells serve as a medium for diffusion between capillaries and neurons 8. Cells line cavities of the brain and spinal cord

Match the types of neuroglia to their functions. (1) ependymal cells (2) oligodendrocytes (3) astrocytes (4) Schwann cells (5) microglial cells A. form a myelin sheath around peripheral nerves B. phagocytize cellular debris and bacteria C. line inner parts of ventricles and spinal cord D. form scar tissue and regulate ion and nutrient concentrations in the CNS E. form a myelin sheath around neurons in the CNS
