Across
  1. 3. Axons with myelin sheaths
  2. 6. Scattered throughout CNS they help forms scars in areas of damage
  3. 10. Provide inner linings that enclose spaces in the brain and spinal cord.
  4. 13. Surrounds the myelin sheath
  5. 14. Narrow gaps between schwann cells
  6. 16. The small space between a neuron and the cell with which it communicates.
  7. 17. Part of a neuron that sends information away from the cell in the form of impulses.
  8. 18. Axons that lack myelin sheaths
  9. 19. Part of the peripheral nervous system under voluntary control.
  10. 21. Part of the peripheral nervous system that is under involuntary control.
Down
  1. 1. Found along axons they provide insulating layers called myelin sheaths.
  2. 2. Rounded area of a typical neuron.
  3. 4. Chemicals released by the conduction of electrical signals
  4. 5. The main functional unit of the nervous system.
  5. 7. Information in the form of electrical changes that is passed from one neuron to another along neural pathways.
  6. 8. Part of the nervous system consisting of the brain and spinal cord.
  7. 9. Nervous tissue that provides physical support, insulation, and nutrients to neurons.
  8. 11. Produce the myelin sheaths around axons of myelinated neurons in the PNS.
  9. 12. Part of the nervous system that consists of nerves.
  10. 15. Part of neuron that receives input.
  11. 20. Found between neurons and blood vessels they provide structural support.
