Across
- 4. passes messages away from the cell body to other neurones, muscles or glands
- 6. covers axon of some neurones and helps speed neural impulses
- 8. a major excitatory neurotransmitter; involved in memory
- 9. the brain and the spinal cord
- 11. nerve cell-consists of many different parts
- 14. sends information from the body's tissues and sensory organs
- 15. cns internal communication
- 17. branches of axon
- 19. composed of sympathetic and parasympathetic nervous system
Down
- 1. influences movement, learning, attention and emotion
- 2. affects mood, hunger, sleep and arousal
- 3. nervous system that arouses the body, mobilizing its energy in a stressful situation
- 4. enables muscle action, learning and memory
- 5. nervous system that controls the body's skeletal muscles
- 7. a major inhibitory neurotransmitter
- 10. helps control arousal and alertness
- 12. takes information from the CNS out to the body's tissues
- 13. receive messages from outer cells
- 16. impulse/Electrical signal traveling down the axon
- 18. the sensory and motor neurones that connect the rest of the central nervous system to the rest of the body
