Nervous System

4. the term used to describe synapses that release NE
6. person going into action
12. nerves connect to the brain
13. transmits sensory messages to central nervous system
14. nerves connect to the spine
15. controls the contractions of the skeletal muscle, which can either be voluntary or involuntary
17. nervous system(CNS) consists brain and spinal cord made of neural tissue, blood vessels as well as connective tissue
18. sensitive processes
19. important organelles involved in the organization of the cytoskeleton and the movement of the chromosomes during mitosis
22. organs that respond to doing something
25. are supporting cells
27. bundles of nerve fibers, carry information in the PNS
28. (stained darkly) areas of the perikaryon contain clusters of RER and free ribosome
30. sensory structures that detect a direct change in the internal environment/respond to a specific stimuli

1. regulates body’s vital functions
2. surrounding cytoplasm
3. a CNS neurotransmitter released in different areas of the brain
5. bundles of neurofilaments extend into the dendrites and axon, providing internal support for these relatively slender process
7. a neurotransmitter that is vital in the brain as well as parts of the ANS
8. action potentials along axons is what moves messages from one area to another in the nervous system
9. has an inhibitory effect
10. is about .2-.5 msec long and is between the arrival of Action Potential at the Synaptic Knob and effect of postsynaptic membrane
11. restores body’s energy
16. causes the opposite, hyperpolarization and lessen action potential generation
20. nerve impulses conducted inward to the central nervous system
21. basic individual functional units of Nervous System
23. nervous system(PNS) consists of all neural tissue out of CNS
24. the cell body
26. causes depolarization and promote action potential generation
29. nerve impulses conducted outward away from the central nervous system
