Across
  1. 2. Pseudounipolar neuron process extending to PNS.
  2. 3. Rapid vesicle/organelle movement (200-400 mm/day).
  3. 5. Cone-shaped region where AP initiates.
  4. 6. Long process transmitting action potentials.
  5. 8. Electrically excitable nerve cells.
  6. 9. Receive signals; form receptive region.
  7. 12. Cytoplasm of axon.
  8. 13. Intermediate filaments maintaining cell shape.
  9. 15. Two processes (e.g., retinal cells).
  10. 16. Pseudounipolar neuron process entering CNS.
Down
  1. 1. Plasma membrane of axon.
  2. 4. Moves cytoskeletal elements (0.5-10 mm/day).
  3. 6. Side branches of main axon.
  4. 7. Single process splitting into peripheral/central axons.
  5. 10. Fine terminal axon branches (synonym: terminal arborization).
  6. 11. Endings releasing neurotransmitters (synonym: synaptic-knobs).
  7. 14. Multiple processes (most CNS neurons).
  8. 16. Neuron's biosynthetic center containing nucleus (synonym: soma).
