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