Across
- 2. the term used to describe synapses that release NE
- 3. surrounding cytoplasm
- 5. bundles of nerve fibers, carry information in the PNS
- 9. sensory structures that detect a direct change in the internal environment/respond to a specific stimuli
- 11. is about .2-.5 msec long and is between the arrival of Action Potential at the Synaptic Knob and effect of postsynaptic membrane
- 12. causes depolarization and promote action potential generation
- 13. nervous system(CNS) consists brain and spinal cord made of neural tissue, blood vessels as well as connective tissue
- 14. the cell body
- 16. regulates body’s vital functions
- 17. person going into action
- 18. controls the contractions of the skeletal muscle, which can either be voluntary or involuntary
- 20. nerve impulses conducted outward away from the central nervous system
- 22. nerves connect to the brain
- 25. action potentials along axons is what moves messages from one area to another in the nervous system
- 28. are supporting cells
- 29. causes the opposite, hyperpolarization and lessen action potential generation
- 30. nervous system(PNS) consists of all neural tissue out of CNS
Down
- 1. bundles of neurofilaments extend into the dendrites and axon, providing internal support for these relatively slender process
- 4. a neurotransmitter that is vital in the brain as well as parts of the ANS
- 6. restores body’s energy
- 7. important organelles involved in the organization of the cytoskeleton and the movement of the chromosomes during mitosis
- 8. has an inhibitory effect
- 10. sensitive processes
- 15. a CNS neurotransmitter released in different areas of the brain
- 19. nerves connect to the spine
- 21. (stained darkly) areas of the perikaryon contain clusters of RER and free ribosome
- 23. basic individual functional units of Nervous System
- 24. organs that respond to doing something
- 26. nerve impulses conducted inward to the central nervous system
- 27. transmits sensory messages to central nervous system
