This assignment is designed to get you thinking about the functions of some of the structures in the central and peripheral nervous system. Listed below are different symptoms or complications that can be attributed to something from the nervous system. List the specific structure that is most likely the root cause of the pathology. In addition, label which branch of the nervous system that structure is a part of (CNS or PNS). I suggest making a table with the pathology in one column, the affected structure in the next column, and the nervous system section in the final column. Two examples are below. It is possible that more than one answer could be correct.
Pathology/Patient
Specific Structure
CNS or PNS?

Identify a neurotransmitter and describe the physiologic consequences associated either with an acute or chronic deficit or excess of the neurotransmitter in the nervous system. Demonstrate your understanding of the material presented in Chapters 12-16 by correctly defining and using at least 4 physiological terms related to the functional organization of the nervous system of humans. Do not present material that you have already presented in the discussion board.
Written Assignment must be 3-4 pages, not including title or reference pages. The paper should include 1-2 strong arguments supported by at least 2 sources. Please make sure your assignment is double-spaced using Times New Roman, 12-point font, and 1” margins. Be sure to cite any references in APA Format
True/False: The autonomic nervous system is “involuntary” therefore the cerebral cortex has no control over this branch of the nervous system.
