Across
- 2. - if only the individual's legs are paralyzed
- 4. - the branching extension of neurons that carry electrical signals to the cell body
- 6. - a group of nerve cell bodies located in the peripheral nervous system
- 9. - cells of the nervous system specialized to transmit messages throughout the body
- 11. - chemical released by neurons that may stimulate or inhibit them
- 13. - phagocytes that ingest debris such as bacteria or dead cells
- 15. - the largest part of the brain that consists of right and left cerebral hemispheres
- 17. - type of CNS supporting cell that forms a myelin sheath
- 19. - brain injury with reversible damage, in which the individual might be dizzy
- 20. - a receptor located in a muscle or tendon (locomotion, posture, and muscle tone)
Down
- 1. - network of nerves formed by joining ventral rami of spinal nerves, which contains both sensory and motor fibers
- 3. - star-shaped cell that form a barrier between capillaries and neurons while protecting them from harmful substances in the blood
- 5. - restoration of the membrane potential to the initial resting (polarized) state
- 7. - brain injury in which the damage is irreversible because of marked tissue destruction
- 8. - completes the pathway between afferent and efferent neurons (also known as an association neuron)
- 10. - automatic reaction to a stimulus
- 12. - the nonneural tissue of the central nervous system that performs supportive and other functions (also known as glial cells/glia)
- 13. - a white, fatty lipid substance
- 14. - a bundle of nerve or muscle fibers bound together by connective tissue
- 16. - the membranes that cover the brain and spinal cord
- 18. - the loss of a state of polarity/the loss of a negative charge inside the plasma membrane
- 20. - the brain area connecting the medulla with the midbrain, which links upper and lower levels of the CNS
