Write a thesis for a Human Physiology Essay

Create a thesis focused on some topic related to physiological plasticity or a pathology. This thesis will then form the core of a 5-7 page paper on that subject.
Keep in mind that the paper will focus on:
1. A description of the characteristics and function of a physiological system as it operates under “normal” or basal conditions
2. A description of how plasticity augments or how pathology disrupts this normal physiological operation/regulation, and
3. A description of how other body systems are affected by the changes in the system(s) you have described in 1 and 2, above. This serves to emphasize the integrative nature of physiology.
In the discussion section of the paper I will have to make an argument about the impact of the pathology/plasticity chosen on human function as described by the thesis.
