The Nervous System
Across
- 3. a molecule that binds to adenosine receptors
- 8. the division of the nervous system that does not include the brain
- 11. pathway that sends information from the CNS
- 12. a neurotransmitter that causes an action potential to occur
- 13. response to an integrated stimuli
- 16. rest and digest
- 17. terminal part of a neuron that send chemical or electrical messages
- 18. part of a neuron that contains the nucleus
- 19. the process of interpreting sensory information
- 22. oligodendrocytes wrap around neurons in the CNS to form this
- 23. pathway that sends information to the CNS
- 25. the neurotransmitter most responsible for happy feelings
- 26. space between an axon terminal of one cell and dendrite of another
Down
- 1. simple, rapid response to a stimuli
- 2. part of a neuron that recieves info
- 4. fight or flight
- 5. involuntary division of the PNS
- 6. a neurotransmitter that can cause hyperpolarization
- 7. period the time it takes for a nerve cell to repolarize after an AP
- 9. transmission of a nerve impulse
- 10. a chemical messenger
- 14. the division of the nervous system that includes the brain
- 15. first step in an action potential
- 20. cell that transmits electrical signals
- 21. cells that support and insulate neurons
- 24. motor division that sends signals to skeletal muscle
