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