What are the functions of the nervous system? 2. What are the divisions of the nervous systems and their respective functions? 3. Draw and label a neuron, what is the function of each piece of the neuron? 4. What are the structural and functional classifications of neurons, how do they relate? 5. What are 4 types of neuroglia found in the CNS? How do they compare to the 2 types of neuroglia in the PNS? 6. What are the functions of the cranial meninges? What are the different layers of the meninges and what role do they play in the overall function? 7. What is the role of the blood brain barrier, how does its structure help maintain its function? What molecules can pass through the barrier? 8. What is cerebrospinal fluid? Where is it produced? How does it flow through the brain? 9. What are the different tracts found in cerebral white matter? What are each of their functions? 10. What are the major lobes of the brain and their respective functions? 11. What are the specific functional areas of the cerebral cortex, there locations and their respective functions? 12. What is the difference between Wernicke’s and Broca’s aphasia? 13. What is hemispheric lateralization? 14. What are the basal nuclei, where are they found, and what are the major functions? If damage is done to the basal nuclei what type of neurological disorders can occur?15. What are the functions of the cerebellum? Where is it found? 16. What are the three major parts of the diencephalon? What are each of their respective functions? 17. What is the limbic system? Where is it found? 18. What are the major parts of the brain stem? What are each of their respective functions? 19. How do all the major regions of the brain contribute to voluntary movement and control of muscles? 20. What are the different layers of connective tissue that cover nerves? 21. What are the different spinal cord enlargements? Where do the nerves run to? 22. What are the different spinal cord plexuses? 23. How do the spinal meninges compare to the cranial meninges? 24. Draw and label the grey matter and white matter of a cross section of the spinal cord, make sure to include a brief summary of what each area is responsible for. 25. What route do nerve impulses take going into and out of the spinal cord? 26. Compare and contrast the major descending and ascending tracts of the spinal cord. 27. What is a reflex arc? What are the various components that make up a reflex arc? 28. How do we classify reflexes? What does each classification mean? 29. What are the 4 major reflex arcs? What are their respective pathways? 30. How does the autonomic nervous system differ from the somatic nervous system? 31. How does the parasympathetic division of the ANS differ from the sympathetic division of the ANS in terms of pre and post ganglionic neurons, signaling pathways, and receptors? 32. What are the different cranial nerves and their
