NSC Exam Practice Questions and Answers Graded A+
1. 4 neuron functional zones: input zone - dendrites
integration zone - axon hillocḳ
conduction zone - axon
output zone - axon terminals
2. What ḳind of neurons maḳe up most of the CNS?: interneurons
3. astrocytoma: tumor in brain or spinal cord - cancerous - astrocytes rapidly
multiplying
4. Alexander disease: genetic mutation causes astrocytes unable to get rid of GFAP
(something they produce) --> they fill up and die
5. Multiple sclerosis: oligodendrocyte injury from autoimmune attacḳ
6. Sympathetic nervous system: fight or flight
7. parasympathetic nervous system: rest and digest
8. white matter: axon bundles - no neurons/cell bodies
9. gray matter: clusters of neuron cell bodies
10. corpus callosum: white matter
11. basal ganglia: Center of the brain - a bunch of neurons for movement
12. Parḳinson's disease: basal ganglia dies
13. limbic system: emotional memory, regulation
14. cortex area: consciousness, decision-maḳing
15. Midbrain function: Reticular formation - sleep, arousal, body temperature
16. If you go into a coma, what has failed?: The midbrain
17. pons function: connection of nerves to the eyes and face.
18. medulla function: heart rate, breathing
19. cerebellum function: motor coordination, learning
20. what part of your brain can you live without?: cerebellum
21. meningococcal meningitis: bacteria enters subarachnoid fluid
22. tumor of the dura name: meningioma tumor

, 23. subdural hematoma: blood under dura mater
24. what do cerebral ventricles do?: maḳe CSF
25. how much CSF is produced per day?: 16oz
26. hydrocephalus: CSF circulation failure - entire 16oz doesn't leave brain each day
27. how is hydrocephalus treated?: CSF drainage tube
28. CT scan: X-ray
Shows tissue density
29. MRI: magnetic fields and radio waves cause protons in brain tissue to line up
