Nervous System
Across
- 3. the sensory division
- 4. the sensory fibers that carry information from the internal organs
- 7. matter collections of myelinated fibers
- 10. nucleus and metabolic center of the cell
- 12. intermediate filaments that maintain cell shape
- 14. collections of cell bodies outside the CNS in the PNS
- 15. the motor division
- 17. the structural classification that includes the cranial and spinal nerves
- 18. the sensory fibers that carry information from the skin, skeletal muscles, and joints
- 19. protect and cushion neuron cell bodies of PNS
- 20. bundles of nerve fibers in the PNS
- 23. matter mostly unmyelinated fibers and cell bodies
- 25. spider-like phagocytes of the CNS
- 26. excitation stimulation of autonomic nervous system
Down
- 1. gap between axon terminals and the next neuron
- 2. produce myelin sheaths for CNS
- 3. most abundant star-shaped CNS glial cells
- 5. "nerve glue"
- 6. the structural classification that includes the brain and the spinal cord
- 8. part of the schwann cell external to the myelin sheath
- 9. conduct impulses away from the cell body
- 11. clusters of cell bodies in the CNS
- 13. conduct impulses toward the cell body
- 16. bundles of nerve fibers in the CNS
- 21. assist with circulation of cerebrospinal fluid
- 22. the involuntary motor division
- 24. form myelin around nerve fibers of PNS
